        This section will discuss what the function or control is
        and how to use it. The subsections are broken down into
        smaller sections for easy access.

 3.1    FRONT PANEL CONTROLS/FUNCTIONS

        The following descriptions are those functions necessary to
        utilize full functionality of the DJ/580T/E.

        (1)  LCD DISPLAY PANEL

             Refer to Section 3.5 for further details on the LCD display
             panel.

        (2)  CONTROL KEYPAD

             The control pad includes 16 multi-functional command keys
             that control and execute various operations for the
             DJ-580T/E. It also serves as a DTMF keypad.

        (3)  MICROPHONE

             An electret condenser microphone is built into the front
             panel. When transmitting, speak directly into the
             microphone from a distance of approximately 5 inches. The
             speaker/microphone connectors are labeled as follows:

             Smaller Jack 
             (MIC JACK):          Tip: PTT Line/Transmit Audio
                                  Ring: 5VDC (for EME-10K option)
                                  Sleeve: Signal Ground

             Larger Jack 
             (SPEAKER JACK):      Tip: Receive Audio
                                  Ring: Remote Control (for EMS-8 option) 
                                  Sleeve: Signal Ground

             If you decide to use the V.U.SP jack while using the
             SPeaker jack, the VHF audio will not be heard. The VHF
             audio is routed through the V.U.SP jack.

        (4)  SPEAKER

             The speaker is located below the key pad on the front
             panel. It's rated at 8 ohms and not in operation when an
             external speaker is used.

        (5)  VHF BAND KEY

             Pressing this key allows for operation on the 2 meter VHF
             band.

        (6)  UHF BAND KEY

             Pressing this key allows for operation on the 70 cm UHF
             band.

        (7)  SHIFT KEY

             The SHIFT KEY is used to change frequency offset and shift.

             The symbols - , + and star symbol are used to indicate
             shifts.

             1. Press and hold the FUNC key, then press the SHIFT key
                repeatedly until the desired shift appears on the LCD
                display.

                The - symbol indicates that the transmitter will
                subtract the offset with the transmitted frequency.

                The + symbol indicates that the transmitter will add the
                offset with the transmitted frequency.

                The star symbol indicates a split offset.




                Simplex operation is active when neither the - or + or
                star symbol is displayed on the LCD display. If OFF
                appears in place of the frequency during transmit, the
                selected frequency is out-of-band.

             2. Select the Main Band by pressing the VHF or UHF key. The
                LCD display returns to frequency.

                                   *** NOTE ***

             For larger incremental frequency changes press and hold the
             FUNC key then rotate the Main Tuning dial. This increments
             the 1MHZ digit. 

             Amateur radio repeaters utilize separate transmitter and
             receiver sections. The transmitter frequency may be offset
             either above or below the receive frequency according to
             repeater coordination conventions. The standard offset for
             the 2 meter band is 600 Khz. Offset for the 70cm band is 5
             Mhz. Offset direction varies according to established band
             plans.

             EXAMPLE: SHIFT

             1. Select the Main Band by pressing the VHF or UHF key.

             change will take place. The beep won't be heard through the
             speaker if it has been turned off.

       (10)  TONE KEY

             The Tone Encoder and Tone (Decoder) Squelch function is
             standard on the DJ-580T/E. Tone Encode and Decode work on
             the Main Band only. The DJ-580T/E has 38 settings from 67.0
             hz to 250.3 hz (TABLE 2). Utilize the TONE key to access
             these settings. Access to an increasing number of repeaters
             is restricted by requiring that a sub-audible tone be
             transmitted with the input signal to open the repeater. To
             select the needed tone, perform the following:

             1. Press and hold the FUNC key, then press the TONE key. A
                tone frequency will appear in the LCD display.

             means that the output power is at mid range for battery
             rating. When L is displayed it means that the output power
             is at the lowest range for battery rating. Refer to the
             battery specifications for more on output levels. 

                              *** WARNING ***

             It is possible to cause UHF receive interference while
             transmitting on VHF. To avoid this from happening, make
             sure that the VHF frequency x 3 does not equal the
             frequency on UHF. For example, if VHF transmit frequency is
             146.190 the UHF frequency should not be set at 438.570.

       (12)  T.SQL KEY

             The Tone Encoder and Tone (Decoder) Squelch function is
             standard on the DJ-580T/E. Tone Encode and Decode works on
             the Main Band only. In other words, it is expected that you
             can only speak on one band at a time. When changing over to
             the other band, another tone may be used. Further
             clarification is made in the cross band repeat section. The
             DJ-580T/E has 38 settings from 67.0 hz to 250.3 hz (TABLE
             3). Utilize the TONE key to access these settings. Access
             to an increasing number of repeaters is restricted by
             requiring that a sub-audible tone be transmitted with the
             input signal to open the repeater. To select the needed
             tone, perform the following:

             1. Press and hold the FUNC key, then press the TONE key. A
                tone frequency will appear in the LCD display.

             2. Rotate the Main Tuning dial or either the UP ARROW or
                DOWN ARROW key to the desired tone frequency.

             3. Select the Main Band by pressing the VHF or UHF key.

             4. Press and hold the FUNC key, then press the T.SQL key to
                display T and enable subaudible tone encoding. If T and
                SQL display, then tone squelch or tone decoding is
                enabled.

             The tone frequency is now stored and will be transmitted
             with the repeater input frequency.

                Tuning Dial. The time is adjustable from 5 to 60
                minutes. 

             3. Press and hold the FUNC key, then press the APO key. APO
                is displayed on the LCD.

                If no activity, a beep is emitted after this time and 30
                seconds later the LCD display becomes blank. Battery
                power has now been removed from the radio. To re-
                initialize APO, turn the radio off and back on again. 

             4. Exit the APO function, select the Main Band by pressing
                the VHF or UHF key. The APO indicator should still be
                displayed on the LCD.
 
             5. To cancel APO, press and hold the FUNC key, then press
                the APO key 2 times. The APO indication should now
                disappear from the display. Exit the APO function,
                select the Main Band by pressing the VHF or UHF key.

             Any signal received during the APO time period, APO resets
             back to the beginning.

       (16)  DOWN ARROW AND FL/PL KEY

             The DOWN ARROW toggles different values depending on
             what task you are utilizing. It is often used to
             decrease VFO frequency value. If this key is held
             down, the value will decrease continuously.

             FL stands for Frequency Lock. In this mode the main keypad,
             SCN/PS and CALL/W keys are locked and don't function. 

             PL stands for Push To Talk Lock. In this mode both bands
             are locked from the Push to Talk switch. Frequencies can
             still be entered and stored.

             These are useful features to prevent unauthorized
             functioning while the radio is in unattended monitoring
             mode. Here's how to use these features.

             1. Press and hold the FUNC key, then press the FL/PL key.
                Each time you press the key, you will toggle the field
                which will be displayed as follows: FL, PL then FL and
                PL and finally both functions disabled.

       (17)  DUAL KEY

             This function is used to monitor two particular channels.
             The possibilities are:

                o VFO and MEMORY channels
                o VFO and CALL channels
                o VFO and VFO channels
                o CALL and MEMORY channels

             In other words, dual channel monitoring will listen to two
             channels. Here's how to make it happen for VFO and MEMORY.
             You can incorporate the same procedure with the other
             possibilities of DUAL WATCH.

             1. Select the Main Band by pressing the VHF or UHF key.

             2. Press the MR key. Select the desired memory channel by
                using the Main Tuning Dial. 

                The 2 digit memory channel number will blink if it
                hasn't been programmed. More on memory channel
                programming can be found in section 6.2. 

             3. Return to VFO Mode and enter a VFO frequency.

             4. Press and hold the FUNC key, then press the DUAL key.
                The PRI indicator will now blink on and off on the
                display. The radio will cycle alternately between VFO
                frequency and Memory frequency for 1/2 second.

             5. When a signal is received, the signal is held for 5
                seconds. 

             6. To release the DUAL/WATCH function, press the PRI or
                chosen VFO key.

       (18)  UP ARROW AND MESS KEY

             The UP ARROW toggles different values depending on what
             task you are utilizing. It is often used to increase VFO
             frequency value. If this key is held down, the value will
             increase continuously.

             This MESS key is used for Digital Signal messages. Refer to
             section 11.7. 

       (19)  PRI/DIAL M KEY

             PRI stands for Priority. When the PRI key is pressed the
             priority function is active. 

             The DIAL M key is used for storing and automatically
             transmit a sequence of numbers/codes. This would be
             commonly used for autopatch use. Refer to section 10 for
             more information.

       (20)  GP DSQ/DSQS KEY

             7. Press and hold the FUNC key, then press the MW key. A
                beep will sound from the speaker and memory channel P2
                will stop blinking. P2 has been successfully
                programmed with the upper frequency.

             8. Select the Main VFO band as you did in step 1.

             9. Press and hold the FUNC key, then press the PS key.
                The display will show scanning of ranges programmed
                between P1 and P2. The P indicator should begin to
                blink on the LCD display.

            10. Exit programmable scan, select the Main
                Band by pressing the VHF or UHF key or SCN
                key.

          MR KEY

             1. Press the MR key to put the Main Band into Memory
                Channel mode. The memory channel number (0-19) will
                appear. A flashing channel number indicates that no
                information has been programmed into this memory
                channel. Turn the Main Tuning dial to increment and
                decrement the memory channel or use the UP ARROW/DOWN
                ARROW keys.

             2. Press the MR key to exit MEMORY MODE and return to VFO
                MODE. The two digit memory channel will disappear from
                the LCD display showing that you have returned to VFO
                MODE. 

             You can scan the memory channels with the SCN key, elect to
             skip any memory channel with the SKIP key, or select the
             scan type with the TMS key. Refer to the section SCANNING
             FUNCTIONS (Section 8) for more information.

             The DJ-580T/E has two (02) banks of memory channels:

             First, the VHF bank has 20 memory channels that are
             accessed with the MR key.

             Secondly, the UHF bank has 20 memory channels that are
             accessed with the MR key.

 6.2.3  CANCELING A MEMORY CHANNEL

             1. Select the Main Band by pressing the VHF or UHF key.

             2. Press the MR key. 

             3. Rotate the Main Tuning Dial to choose the desired memory
                channel number (clockwise to increase, counter clockwise
                to decrease).  Select a non-flashing memory channel
                number (0 to 19).

             4. Press and hold the FUNC key, then press the MW key to
                cancel this memory channel. The two digit memory channel
                number will now begin to flash indicating that the
                content of this memory channel has been cleared.

 6.2.4  ALLOCATION OF MEMORY CHANNELS

        Using this feature will allow you to free up memory
        channels from either band and allocate to the other band
        for frequency storage. 

        EXAMPLE: FREE MEMORY CHANNELS

        Lets say you wish that you had 25 programmable VHF memory
        channels but the radio comes defaulted to 20. No problem,
        that's why this feature has been included. Since the radio
        has 40 channels in total, 20 for each VFO, it is possible
        to allocate all 40 channels to one band for memory
        programming. This scenario would leave the other band with
        no programmable memory channels. Here is how to make it all
        happen.


             1. Press and hold the FUNC key, then press the * key. The
                symbol FL will appear on the LCD display.

             2. Press and hold the FUNC key, then press the 1 key. The
                number of allocated memory channels for each VFO will
                appear on each band display.

                When the Main Tuning Dial is rotated clockwise, the
                number of possible VHF memory channels will increase.
                This number will increase while the allocated memory
                channels from the UHF side will decrease. 

                When the Main Tuning Dial is rotated counter clockwise,
                the number of possible UHF memory channels will
                increase. This number will increase while the allocated
                memory channels from the VHF side will decrease.

             3. Press and hold the FUNC key, then press the * key four
                (4) times to clear FL/PL from the display and exit beep
                tone level mode.

             5. Press the PRI key to begin priority function. The LCD
                will display PRI.

             6. Press the PRI key to stop the priority function. The LCD
                will remove PRI from the display.

                               *** NOTE ***

          When a signal is received on the VFO frequency a BEEP will be
          emitted once from the speaker.

          In memory priority, the transmitter may be activated on either
          frequency. Press the PTT switch when the desired frequency is
          displayed on the LCD.

 7.3    CALL PRIORITY

        The VFO frequency or Memory channel is scanned for
        approximately 1/2 second and the programmed CALL frequency
        is scanned for approximately 4 seconds.

             1. Select the Main Band by pressing the VHF or UHF key.

             2. If the CALL channel hasn't been programmed yet, refer to
                section 6.3.1 for more information.

             3. Enter a frequency into the VFO or select a Memory
                channel in memory channel mode.

             4. Press the CALL key for approximately 1/2 second. Call
                priority will begin to cycle between the CALL channel
                and the selected VFO or memory channel. 

             5. Press the PRI key to begin priority function. The LCD
                will display PRI.

                               *** NOTE ***

          When a signal is received on the VFO frequency a BEEP will be
          emitted once from the speaker.

          In CALL priority, the transmitter may be activated on either
          frequency. Press the PTT switch when the desired frequency is
          displayed on the LCD.

 7.4    DUAL WATCH FUNCTION

        Unlike priority, there is no period for listening between
        two modes. Dual Watch is a constant monitoring of two
        modes. 

 7.4.1  VFO/MEMORY DUAL WATCH

        Perform the following for VFO/MEMORY DUAL WATCH.

             frequencies is approximately .5 second.

          4. Press the VFO button as selected in step #1 to stop DUAL
             WATCH.

 8      SCANNING FUNCTIONS

        The DJ-580T/E offers various scanning options and 3
        scanning modes described a little later on in this section.
        First lets look at the scanning options, they are:

        VFO Scan                      - Scans either band           
                                        independently.

        Program Band Scan (VFO Mode)  - Scans programmed lower to
                                        upper frequencies. You may scan a   
                                        range of frequencies.


        Memory Scan                   - Each band may scan memory
                                        channels independently.







 8.1    VFO SCAN

        Each band may scan VFO channels independently. When in Band
        Scan mode the DJ-580T/E scans by Channel step, by 100 kHz
        or by 1 MHz steps. As the scan passes through any 500 kHz
        or 1 MHz point a tone will sound if the BEEP function is
        active.

             1. Select the Main Band by pressing the VHF or UHF key
                twice. The purpose for pressing the band key twice is in
                the event you are in memory mode by mistake.

             2. Press the SCN key for approximately 1 second and release
                the SCN key. Use the Main Tuning dial or UP ARROW or
                DOWN ARROW keys to scan in a particular direction.

             3. Whether you are cycling upward or downward, during scan
                the decimal point will flash indicating that scanning
                has begun.

             4. When a signal is received, scanning will stop and remain
                on that frequency. When channel goes quiet or Main
                Tuning Dial is rotated clockwise or counter clockwise,
                scanning will continue.

             5. To cancel scanning press the SCN key. 

             All 3 scan types can be applied to Band Scan.

 8.1.1  PROGRAM BAND SCAN MODE (VFO MODE)

        This scan option allows the scanning of a range of VFO
        frequencies. Each band may have independent scan ranges.
|       The lower band limit is programmed into Memory Channel P1. The
|       upper band limit is programmed into Memory Channel P2. You may
        initiate Program Band Scan from either VFO or Memory mode.

        EXAMPLE: STORING LOWER/UPPER RANGES

             1. Select the Main Band by pressing the VHF or UHF key, for
                example VHF.

             2. Enter a desired Lower Frequency via the key pad, for
                example "146.000".

             3. Press the MR key.

             4. Rotate the Main Tuning Dial until P1 is displayed.

             5. Press and hold the FUNC key, then press the MW key to
                store the selected Lower Frequency into memory.

             6. Enter a desired Upper Frequency via the key pad like
                146.100.

             7. Press the MR key. 

             8. Rotate the Main Tuning Dial until P2 is displayed.

             9. Press and hold the FUNC key, then press the MW key to
                store the selected Upper Frequency into memory.

            10. Press and hold the FUNC key, then press the SCN key.
                The letter P will begin to blink on the display.
                Scanning from 146.000 to 146.100 has begun. 

            11. Press the Main Band key as performed in step 1 to
                stop this function. Pressing the SCN key will also
                cease this function.

                               *** NOTE ***

             The upper limit frequency and Lower limit frequency may be
             stored into either P1 or P2.

 8.2    MEMORY SCAN MODE

        This scan option allows the user to scan frequencies that
        have been programmed in any (or all) of the memory
        channels. Bands may be scanned individually or both bands
        may be scanned simultaneously.

             1. Select the Main Band by pressing the VHF or UHF key
                twice. The purpose for pressing the band key twice is in
                the event you are in memory mode by mistake.

             2. Press the MR key.

             3. Press the SCN key. Use the Main Tuning dial to scan in a
                particular direction. You can also use the UP or DOWN
                ARROW keys to scan in a particular direction.

             4. Whether you are cycling upward or downward, during scan
                the decimal point will flash indicating that scanning
                has begun.

             5. When a signal is received, scanning will stop and remain
                on that frequency. When channel goes quiet or Main
                Tuning dial is rotated clockwise or counter clockwise,
                scanning will continue.

             6. Press the Main Band key as performed in step 1 to stop
                this function. Pressing the SCN key will also cease this
                function.
             
 8.2.1  MEMORY CHANNEL SKIP MODE

        Memory Channel Skip permits unwanted memory channels to be
        skipped during memory scan. This step presumes that you
        have already programmed some/all memory channels.

             1. Press the MR key.

             2. Rotate the Main Tuning Dial until the memory channel
                that you want to skip is displayed.

             3. Press the SKIP key. The decimal point will disappear
                from the frequency displayed, indicating this frequency
                will be skipped. Perform step 2 and 3 for each memory
                channel that you wish to skip.

             4. To cancel Memory Channel Skip, press the SKIP key again.
                The decimal point will re-appear, and that memory
                channel will now be restored to scan status.

 8.3    SCANNING TYPES

        The DJ-580T/E offers 3 different scanning modes as shown
        below. The initial factory setting is the Busy Channel
        Scan.

        Busy Scan  - Stops at a busy channel or frequency until
                     clear. Two seconds after the signal ceases, scanning   
                     resumes.

        Timed Scan - Stops at busy channel or frequency, then
                     resumes scan 5 seconds later even if the
                     channel remains busy. Scanning will also
                     resume when a signal received ceases.

        Selecting a Scan Type:

             1. Select the Main Band by pressing the VHF or UHF key.

             2. Press and hold the FUNC key, then press the TMS key. A
                black block with a white lettered T will appear,
                indicating to you that "Timed Scan" has been selected.

             3. Press and hold the FUNC key, then press the TMS key
                again to leave "Timed Scan". The black block with a
                white lettered T will disappear from the LCD display.

             The DJ-580 will be in "Busy Scan" when not in "Timed Scan".



 8.4    OTHER SCANNING INFORMATION

        This subsection talks about all other information pertinent
        to radio scan.

 8.4.1  DUAL BAND SCAN

          You may want to scan both bands at the same time. You can
          perform that function by following this example.

          EXAMPLE: DUAL BAND SCAN

             1. Press the VHF key.

             2. Press the UP ARROW key for approx. 1 second.

             3. Press the UHF key.

             4. Press the UP ARROW key for approx. 1 second.

 8.4.2  DUAL BAND SCANNING WITH MEMORY PRIORITY

          If you want to activate PRIORITY on both bands while SCANNING,
          no problem, follow this example.

          EXAMPLE: DUAL BAND SCAN WITH DUAL BAND PRIORITY

             1. Press the VHF key.

             2. Press the MR key and rotate Main Tuning dial for a

             7. Press the MR key and rotate Main Tuning dial for a
                desired memory channel.

             8. Press the UHF key.

             9. Press the SCN key for approx. 1 second.

            10. Press the PRI key.




 9      REPEATER OPERATIONS

        Amateur radio repeaters utilize separate transmitter and
        receiver sections. The transmitter frequency may be offset
        either above or below the receive frequency according to
        repeater coordination conventions. 

 9.1    SPLIT FREQUENCY FUNCTION

        When standard offsets will not satisfy an input or output
        frequency, a split is utilized for this purpose. Split can
        be configured on the DJ-580 for VFO and MEMORY modes. The
        split frequency function will not operate in CALL mode.

 9.1.1  VFO MODE SPLIT

        Perform the following for VFO MODE SPLIT.

             1. Select the Main Band (VFO) by pressing the VHF or UHF
                key. Enter a frequency into the VFO for your output
                (receive) frequency.

             2. Press the MR key. Program or select a frequency in any
                MEMORY channel for your input (transmit) frequency.

|            3. Enter VFO as selcted in step 1. VFO frequency is used
|               for receive and the MEMORY channel is used for transmit.
                
             4. Press and hold the FUNC key, then press the SHIFT key
|               repeatedly until the star symbol appears on the display.
                The split setup is now complete.

 9.1.2  MEMORY MODE SPLIT

        Perform the following for MEMORY MODE SPLIT.

             1. Press the MR key. Program or select a frequency in any
                MEMORY channel for your input (transmit) frequency.

             2. Select the Main Band (VFO) by pressing the VHF or UHF
                key. Enter a frequency into a VFO for your output
                (receive) frequency.

|            3. Press the MR key again. MR frequency is used for receive
|               and the VFO frequency is used for transmit. 

             4. Press and hold the FUNC key, then press the SHIFT key
|               repeatedly until the star symbol appears on the display.
                The split setup is now complete.



 9.2    REV KEY

        In some areas there may be repeaters operating on repeater
        frequency pairs, the exact reverse of another repeater in
        the area. That is, the input of one repeater is the output
        frequency of the other and vice versa. To avoid the
        inconvenience of reprogramming every time both repeaters
        are in range, the REV key allows instant reversal of the
        input and output frequencies and the offset direction. The
        REV function is also useful to check the repeater input to
        determine if another station is heard directly so you can
        go simplex. To activate the REV function:

             1. Press and hold the FUNC key, then press the REV key. The
                repeater input frequency and opposite SHIFT indicator
                will appear on the LCD display panel.

             2. Press and hold the FUNC key, then press the REV key
                again to cancel the REV function.

 9.3    RESETTING RADIO

*** NOTE ***

             Resetting the radio will erase all user programmed
             information (frequencies,shifts,offsets etc.) Make sure
             that this information has been written down before
             proceeding.

             1. Make sure radio is powered off.

             2. Press and hold the FUNC key in while turning on the
                radio via the power knob. The LCD will display 145.00
                (VHF) and 445.00 (UHF).

                               *** NOTE ***

             If you were to hold the FUNC key in and not let it go while
             powering up the radio, all display segments will be shown.

 9.4    CTCSS ENCODE/DECODE

        CTCSS encoding allows you to select the proper tone
        frequency to open another operators radio receiver or
        repeater. CTCSS decoding enables another operator to select
        the tone your receiver requires enabling you to hear them.
        Unlike Code Squelch operation (Refer to section 11 for
        details), a specific tone frequency is used. Here's how to
        use CTCSS Encoding/Decoding.

             1. Select the Main Band by pressing the VHF or UHF key.

             2. Press and hold the FUNC key, then press the TONE key. 

             3. Rotate the Main Tuning dial to the desired tone.

             4. When the tone has been selected enter the Main Band by
                pressing either the VHF or UHF key.

             5. Press and hold the FUNC key, press the T.SQL key
                repeatedly. Tone settings will cycle each time the T.SQL
                key is pressed. It cycles as follows on the LCD display:

                o The Tone Encoder is Enabled when the letter T is
                  displayed on LCD.

                o The Tone Decoder Squelch function is enabled when the
                  letter T and SQL is displayed on the LCD. When this
                  function is active, you would expect a particular tone
                  to open your radio receiver.

                o When the T and SQL is not displayed, the
                  encoder/decoder is disabled.

             EXAMPLE: TONE ENCODER/DECODER 

                Radio for Joe              Radio for Linda
                -------------              ---------------
                Tone set: 100.0            Tone set: 100.0              
                T displayed (ENCODE)       T and SQL displayed (DECODE)

             A) Radio operator "Joe" is calling "Linda". The interesting
                point here is that when the radio that Linda is using
                displays T and SQL, nothing will be heard through her
                radio speaker when squelch is opened up (fully counter
                clockwise). You will notice however that the S/RF
                indicator will be shown on the LCD when squelch is
                opened.

             B) The only way that Linda will hear Joe is for Joe to send
                the proper tone to open Linda's radio receiver. If Joe
                doesn't send the right tone, Linda's radio will remain
                silent.

tt      AUTOPATCH OPERATION (AUTOMATIC DIALER)

        The DJ-580T/E offers three automatic dialer memories. A
        telephone number may be entered in either the VHF or the
        UHF frequency mode. The stored telephone number is
        transmitted on whichever band is selected as the Main Band.



        
10.1    PROGRAM AUTODIAL NUMBER

         To enter a telephone number, perform the following:

             1. Press and hold the FUNC key, then press the A key. The
                selected VFO frequency display will clear and display C1
                or C2 or C3. Rotate the Main Tuning dial clockwise or
                counter-clockwise to obtain a desired dialer memory. The
                telephone symbol will display on the LCD and flash,
                indicating that the dialer memory is ready to accept the
                number to be stored. You may enter up to 16 numbers,
                letters and symbols, four at a time in four groups.

             2. The telephone number or codes should be entered in order
                from the beginning. The following characters can be
                used:
                              0-9, A-D, *, #

             3. Press and hold the FUNC key, then press the A key to
                store the entered telephone number or codes. The
                telephone symbol stops flashing and is on steady to show
                that this function is active.

                Proceed to Section 10, 10.4 to transmit the dial
                sequence. Clear out dialer memory to enter a new
                sequence. 

10.2    CLEAR DIALER MEMORY

             1. Press and hold the FUNC key, then press the A key.

             2. Rotate the Main Tuning dial to the dialer memory you
                wish to clear.

             3. Press and hold the FUNC key, then press the C key
                followed by the A once again.

10.3    CORRECTING CODES IN DIALER MEMORY

             1. Press and hold the FUNC key, then press the A key.

             2. Rotate the Main Tuning dial to the dialer memory you
                wish to make a correction in.

             3. Press and hold the FUNC key, then rotate the Main Tuning
                dial until the sequence of digits you wish to correct
                have just exited the display. 

             EXAMPLE: CORRECTING DIALER CODES

                Programmed number is 123567890, but you forgot 4!

             1. Press and hold the FUNC key, then press the A key.

             2. Rotate the Main Tuning dial to the dialer memory you
                wish to make a correction in.

             3. Press and hold the FUNC key, then rotate the Main Tuning
                until the numeral 3 is displayed.

                This represents the last digit displayed on the LCD.   
                | These digits are hidden just right of last digit shown.
                v vvvvvv 
              123 567890

             4. Now enter 4567890. After you play with this for awhile
                you will see how it works. 

10.4    TRANSMIT/CHANGE AUTODIAL NUMBER

        After performing the steps in section 10.1, perform the
        following steps to transmit the programmed number.

             1. Press and hold the FUNC key, then press the "A" key.

             2. The telephone symbol could be blinking which represents
                an unprogrammed dialer memory channel. Refer to Section
                10. Otherwise, rotate the main tuning knob to the
                desired dialer memory channel.

        Verify that the blinking telephone symbol appears on the
        LCD display.

             3. Press the PTT switch for an instant. This will return
                you to VFO mode.

             4. To transmit dialer memory channel, Press and hold the
                PTT key. 

                        ** LOOK AT LCD DISPLAY ** 
  
                You are now transmitting. The ON AIR symbol should
                display on the LCD display.  

             5. While transmitting press the FUNC key to send/transmit
                the autodial sequence.

                               ** LISTEN ** 
  
                The dialer sequence that you programmed earlier will be
                transmitted. You can hear the tones that are being sent
                through the DJ-580 speaker.


                          HIDDEN FUNCTIONALITY

        This is where you will have to experiment a bit. You can
        change the dialer sequence timing. Refer to Section 10.7
        for all of these new details.

10.5    MANUAL DIAL

        In some instances you may want to dial a number manually.
        perform the following steps.

             1. The telephone symbol should not appear on your display.
                If it does, press and hold the FUNC key, then press the
                A key, the C key and finally the A key again.

             2. Press and hold the PTT key.

             3. Now dial the number on your keypad as you would a
                telephone.

10.6    DISABLE AUTODIAL

             Performing the following step will erase a stored
             number in the autodialer.

             1. Press and hold the FUNC key, then press the A key, the C
                key and finally the A key again. 

             You can either clear the dialer channel or not press the
             FUNC key during a transmission. 

10.7    DIALER RATE ADJUST

             The following steps are used for changing the
             dialer and dsq tone rates. This function may not
             appear/be available on earlier DJ-580 units.

             1. Press the * key. The symbol FL will appear on the LCD
                display.

             2. Press the following keys in sequence: #, 1, 2, 3. The
                LCD will display the letter C. If you repeat this step
                continiously the letters will change as follows:
                C,D,upside down A,H,0,1,2,3,4,5,6,7,8,9,A,B

|            Each of these indicators are associated with a different
|            rate during transmission. The fastest begins at 1 and the
|            slowest is zero. The letters are variations of slow rates.





11      DIGITAL SQUELCH (DSQ) 

        DSQ stands for DTMF Squelch Control. DSQ is very versatile
        and will allow you to:

          o  Make a transmission that will specifically be heard by a
             particular group (of your choosing, by a code sequence).
          o  Place a private call to a selected person in a group.
          o  Call a single operator.
          o  Straight DSQ transmission

        This feature is achieved by use of DTMF Tones that will either open
        (or keep closed) the DJ-580T/E. In this section you will learn how
        to transmit and receive the DSQ SCHEME! A radio must be DSQ
        compatible to take advantage of these features.

11.1    DSQ SCHEME

        Before we get started let's look at the DSQ tone structure.
        Depending on the transmission type (Group, Private etc.), a
        particular tone sequence will be sent. The tone structure
        is broken down into the following areas:

             o  GROUP Code - 3 digit sequence
             o  OTHER'S Code - 3 digit sequence
             o  OWN Code - 3 digit sequence
             o  MISC Codes

        The following explanation of each area will help you to
        fully understand how each is utilized.

        3 DIGIT "GROUP" CODE 
 
        By programming a 3 digit group code your members of a group
        would receive a common transmission. Perhaps this group
        wouldn't want to hear a transmission meant for another
        group that has another 3 digit code sequence. 
 
        EXAMPLE: GROUP CODE 
 
        Lets say that you are helping the local police department
        find a missing child. They have split 10 radio operators
        into 2-five person teams. Let's call them team 1 and team
        2. 

        Each member of team 1 has a radio with a group code of 111. 
        Each member of team 2 has a radio with a group code of 222. 
 
        The police have just found evidence that the child is
        definitely located in team 2 territory. The central
        transmission point now needs to contact the members of team
        1 and notify them that their search area must be changed.
        They will send out a 111 group code (tone sequence) to team
        1. By virtue of the group code 111, all members of team 1
        will hear the message and team 2 will hear nothing on their
        radios. A separate transmission to group 2 could be placed
        with specific updated information!

        3 DIGIT "OTHER'S" CODE 
 
        This code is used as an identifier of another station. In
        other words, it is the other persons "own" code.  

        EXAMPLE: OTHERS CODE 

        Lets say that an individual in team 1 needs to be given
        some specific information. The receiving stations
        identifier is referred to as the other's code. We will send
        that person the information by virtue of their 3 digit
        "own" code. You must enter their "own" code into your
        "others" code field.  

        3 DIGIT "OWN" CODE 
 
        A transmitting station uses 3 digits as a personal
        identification number. A receiving station uses this code
        to identify who called them.  

        EXAMPLE: OWN CODE

        Lets say that you will receive some specific information.
        The other person will need to know your "own" code before
        your radio will receive a private call. Your "own" code is
        also  necessary, because the other person receiving your
        message will see your "own" code displayed on their radio
        LCD.

        MISC CODES

        16 numbers, letters and symbols can be used for coding.
        Here's what you can use; 0-9, A-D, * and #. An "H" will
        appear on the LCD when the * is entered and upside down A
        will appear when the # is entered. The # sign is used as a
        wild card. Refer to WILDCARD for more information. 

11.2    PROGRAMMING ALL DSQ CODES

        Place your radio in front of you. The following steps get
        your radio set for DSQ operation.

             1. Select the Main Band by pressing the VHF or UHF key.

             2. Press and hold the FUNC key, then press the B key. The
                LCD display will indicate A-000.

             3. Enter 3 digits for the group that YOU want to call. In
                other words, a unique calling code for a specific group.

                EXAMPLE: PROGRAM 1ST GROUP CODE

                                   A-123

             4. Rotate the Main Tuning dial clockwise until B-000 is
                displayed on the LCD.

             5. Enter 3 digits for another group that YOU might call.
                This is an additional group calling code.

                EXAMPLE: PROGRAM 2ND GROUP CODE

                                   B-456

             6. Rotate the Main Tuning dial clockwise until P-000 is
                displayed on the LCD.

             7. Enter 3 digits for your "own" Personal code. This is
                your unique identification code.

                EXAMPLE: PROGRAM YOUR OWN CODE

                                   P-100

             8. Rotate the Main Tuning dial clockwise until y-000 is
                displayed on the LCD.

             9. And now you must select the "others" 3 digit code. This
                is the operator you're calling. Lets say you're calling
                operator 200, enter "200" on the keypad. 

                EXAMPLE: PROGRAM THE OTHERS CODE

                                   y-200

            10. Rotate the Main Tuning dial clockwise until nn-00 is
                displayed on the LCD.


            11. Enter a two digit code that will become the Digital
                Signal Message.

                EXAMPLE: DIGITAL SIGNAL MESSAGE

                                   nn-07

            12. Press the VHF or UHF key to end setup.


          Only radios with DSQ functionality are capable of receiving
          and/or transmitting DSQ tasks. These tasks are described in the
          following sub-sections, have fun!

11.3    DSQ MODES

        This section will address all functions of DSQ and describe
        how they should be used. Only through experimentation of
        DSQ will you get the hang of it. DSQ functionality comes in
        various flavors, and they are shown in the following table.

                     DSQ FUNCTION               LCD DISPLAY
             -----------------------------   -----------------
                     Straight DSQ                    D.SQ  
                     Group Calling               G   D.SQ
               Private Calling In A Group        G P D.SQ
                     Private Call                  P D.SQ

11.3.1  TRANSMITTING (CODE SQUELCH)

        Coded Squelch is a unique 3 digit sequence, when sent to
        another unit configured only for D.SQ, will open the
        receiver for reception. It's always a good idea to have a
        cheat card that lists each units identifier (own code) and
        group codes.

             1. Select the Main Band by pressing the VHF or UHF key.

             2. Press and hold the FUNC key, then press the B key.

             3. Rotate the Main Tuning dial and select either A- for
                GROUP A or B- for GROUP B. Each group should have a
                unique identifier code. If either GROUP A or B doesn't
                contain the desired 3 digit code, enter it in at this
                time via the keypad.

             4. Return to the Main Band as selected in step 1.

             5. Press the B key several times until "D.SQ" displays on
                the upper right-hand corner of the LCD. 

             6. When you press the PTT key, the Code Squelch is
                transmitted automatically. At the conclusion of the 3
                digits being transmitted, the operators radio (who you
                are calling) receiver will accept your transmission.

11.3.2  RECEIVING (CODE SQUELCH)

        If the received Code Squelch signal matches the set Code
        Squelch code, D.SQ will begin to flash on the LCD display.
        In addition, an audible alert will be heard through the
        speaker.

          If the receiver is on receive mode by code squelch, it is
          possible to communicate within 1.5 seconds after a received
          signal is clipped.

11.3.3  TRANSMITTING (GROUP CALLING)

        When you select this option, you will be able to contact
        many operators that collectively make up a group. If
        operators with compatible DSQ functionality are configured
        correctly, and all have the same group code programmed,
        their radios should open and receive your call. It's always
        a good idea to have a cheat card that lists each units
        identifier (own code) and group codes. Here's what you have
        to do.

             1. Press the B key. 

             2. Rotate the Main Tuning dial and select either A- for
                GROUP A or B- for GROUP B. Each group should have a
                unique identifier code.

             3. Press the B key several times until G D.SQ displays on
                the upper right-hand corner of the LCD. 

             4. When you press the PTT switch, the GROUP code selected
                will be transmitted to all units in the GROUP.

             If you are using GROUP A in step 2 and wish to change to
             GROUP B, follow steps 1-4 again.

          The following DSQ code is transmitted as shown:

                 (3 DIGIT GROUP CODE) * (3 DIGIT OWN CODE)

11.3.4  RECEIVING (GROUP CALLING)

        To receive DSQ coded calls in GROUP CALLING, setup your
        radio for G DSQ as follows:

             1. Press and hold the FUNC key, then press the B key until
                G DSQ appears on the LCD display.

        When the received DSQ code matches the first 3 digits of
        your display (group code), the G DSQ indicator will begin
        to flash. If the BEEP is off, the squelch will open for as
        long as the calling operator is transmitting. If the BEEP
        is on, an audible beep will be emitted from the radio and
        the indicator will display which group is calling. Reset
        the display by pressing the Main Band key or PTT.



11.3.5  TRANSMITTING (PRIVATE CALLING IN A GROUP)

        It's always a good idea to have a cheat card that lists
        each units identifier (own code) and group codes.

             1. Press the B key. 

             2. Rotate the Main Tuning dial and select either A- for
                GROUP A or B- for GROUP B. Each group should have a
                unique identifier code.

             3. Press the B key several times until GPDSQ displays on
                the upper right-hand corner of the LCD. 

             4. Press the PTT switch to transmit the DSQ code or press
                the VFO key for the band you are working.

          The following DSQ code is transmitted as shown:

      (3 DIGIT GROUP CODE) (1 DIGIT OTHERS CODE) * (1 DIGIT OWN CODE)

11.3.6  RECEIVING (PRIVATE CALLING IN A GROUP)

        To receive DSQ coded calls in PRIVATE CALL IN A GROUP,
        setup your radio for GPDSQ as follows:

             1. Press and hold the FUNC key, then press the B key until
                GPD.SQ appears on the LCD display.

        When the received DSQ code matches the first 3 digits of
        your group and your own code, the DSQ GP indicator will
        begin to flash. If the BEEP is off, the squelch will open
        for as long as the calling operator is transmitting. If the
        BEEP is on, an audible beep will be emitted from the radio
        and the indicator will display which group is calling.
        Reset the display by pressing the Main Band key or PTT.

11.3.7  TRANSMITTING (PRIVATE CALL)

        This option would be used when someone is calling only you.
        This is different from encode/decode because you determine
        your own identification code and not a subaudible tone.
        It's always a good idea to have a cheat card that lists
        each units identifier (own code) and group codes.

             1. Press the B key. 

             2. Press the B key several times until P D.SQ displays on
                the upper right-hand corner of the LCD. 



             4. Press the PTT key to transmit the DSQ code or press the
                VFO key for the band you are working.

          The following DSQ code is transmitted as shown:

                (3 DIGIT OTHERS CODE) * (3 DIGIT OWN CODE)

11.3.8  RECEIVING (PRIVATE CALL)

        To receive DSQ coded calls in PRIVATE CALL, setup your
        radio for P D.SQ as follows:

             1. Press and hold the FUNC key, then press the B key until
                P D.SQ appears on the LCD display.

11.4    ERROR CODE

        When the "Other's" private code is not confirmed the LCD
        display will indicate "Er".

11.5    TIMING CONSIDERATIONS

        On occasions you may find that the operation of DSQ through
        some older repeaters may be unpredictable. This occurs on
        initial transmit with your DJ-580. When you transmit, a
        time delay occurs before the repeater is fully
        transmitting. The DJ-580 will begin to transmit the DSQ
        tone sequence during the repeater transmit delay. The
        DJ-580 can delay 450 ms or 750 ms. In addition, the 
        timing period for the tone burst sequence can be adjusted.
        Please refer to section 10.7 for more information.
 
        It is possible to delay the time to transmit codes to about
        750ms after the PTT key is pressed.

             1. Press and hold the FUNC key, then press the * key. The
                LCD display will display FL.

             2. Press and hold the FUNC key, then press the 4 key. The
                LCD display will display d-750 or d-450. Repeat this
                step until the desired selection is made.

             3. Press and hold the FUNC key, then press the * key.
                Repeat this step until FL and PL is absent from the
                display.






             
11.6    DSQ WILDCARDS 

        The # symbol is a wildcard that may be substituted for any
        one digit,letter or symbols used in DSQ codes. When the #
        symbol is entered it appears on the LCD display as an
        upside down A. The wildcard allows for the combination of
        many groups. If the first or first and second digits of
        several group codes are the same, you can replace the
        second and third digits (or just third digit) with a #
        mark, and thus transmit to all those groups.

          EXAMPLE: WILDCARDS 

             1. Enter the 2 meter frequency of 146.520.

             2. Press and hold the FUNC key, then press the DSQS key.
                Select any code squelch memory channel.

             3. Release the FUNC key now and select a 3 digit code
                squelch code using the keypad.

                Example: Enter the 3 digit code 1#5.

             4. Press the FUNC key to return the LCD display to
                operating frequency.

                Example: Now you will see on the LCD display P45.52. 

             5. Press the D.SQL key repeatedly (2 times) until C appears
                in the 100 MHz digit location.

                Example:   C45.620

          If the incoming coded calls are anyone with a group code as
          follows, the call will be received by your radio.

             o  105 through 195
             o  1A5 through 1D5
             o  1*5
             o  1#5

             6. When you receive a call from another station, the C will
                flash on and off for as long as the other operator is
                transmitting. Your radio has already memorized who was
                calling you, so press the PTT switch and you will
                transmit to that station directly. When you have
                completed your QSO, enter the wildcard sequence again to
                open your radio to all other stations again.




11.7    DIGITAL SIGNAL MESSAGE

        This function allows you to send or receive messages
        consisting of 2 digit codes.

11.7.1  TRANSMITTING DIGITAL SIGNAL MESSAGE

        You can retain 1 signal message in the transmitter memory.

             1. Press and hold the FUNC key, then press the B key.

             2. Rotate the Main Tuning dial and select a message memory
                channel nn.

             3. Enter a 2 digit message code. This is a code that has
                been predetermined and understood by the operating
                parties.

             4. Press the VHF or UHF key to end setup.

             5. Set the appropriate paging function (D.SQ, G D.SQ etc).

             6. Press the PTT key to transmit the DSQ code. Continue to
                hold the PTT key and press the CALL key. 

             What the receiving operator will see on the display will be
             the unit number f the calling station followed by the 2
             digit code. The following is the sequence sent:

                        # (2 DIGIT SIGNAL MESSAGE)

11.7.2  RECEIVING DIGITAL SIGNAL MESSAGE

             1. Set the appropriate paging function (D.SQ, G D.SQ etc).

             2. When the appropriate codes are received, your receiver
                will open to hear the calling operator. When the digital
                signal message is sent shortly after the initial
                transmission, you will see on the LCD display the 3
                digit calling station followed by a - and then the 2
                digit digital signal message.

11.7.3  TRANSMITTING WITH DIGITAL SIGNAL DISPLAYED

        While a digital signal message is displayed, press the PTT
        switch. Your signal will be transmitted back to the station
        calling by using the displayed DSQ settings. The frequency
        will return to your LCD display.




11.7.4  REVIEW DIGITAL SIGNAL MESSAGE MEMORY

        You can store up to 3 previously received digital signal
        messages. The first two memories store the messages in
        received order. The third memory stores the latest message.
        These messages display the 3 digit calling station followed
        by the 2 digit message. Here's how to view digital signal
        message memory.

             1. Press and hold the FUNC key, then press the MESS key.
                Select any code squelch memory channel. The latest
                message will be displayed on the LCD display.

             2. Rotate the Main Tuning dial to review the previously
                sent messages in n1 through n2. You can also use the
                arrow keys to review these messages.

11.7.5  CLEARING MESSAGE MEMORY

        If you find it necessary to clear out messages, proceed
        with the following steps.

             1. Select the memory number and press the C key once to
                clear out that location.

12      CROSS BAND REPEATER 

        The DJ-580 is capable of cross band repeat. To simplify
        matters, it means that when you transmit on one band it is
        simultaneously heard on the other band. Ok you want to set
        up a cross band repeater? Here are a few things to remember
        about cross band repeat:

             1. When cross band repeat is active, you cannot change
                frequencies or utilize other functions with the
                exception of cross band deactivation.

             2. Set squelch threshold before you activate cross band
                repeat.

             3. No radio modification is necessary to activate this
                function.

             4. This isn't a 100% duty cycle repeater. If
                the radio becomes extremly hot to the
                touch, the radio should be allowed a cool
                down time.

             5. Use cross band repeat in eith Low or Mid power only.  

|            6. Cross band repeat will not allow for different CTCSS
|               Encode/Decode tones on each band.

|            Using cross band repeat allows a user to enter on one
|            band and cross over to the other band. You may use shifts
|            or operate in simplex operation. 

12.1    ACTIVATE CROSS BAND REPEATER

        Here are the steps for cross band repeat.

             1. Rotate the volume controls for the VHF and UHF bands
                fully counter-clockwise.

             2. Press and hold the FUNC key, then press the FL key. The
                LCD should display FL. 

             3. Press each key once as follows: #, 5, 0 and 8. You
                should notice that the word oPEn displays on the LCD and
                the opposite band indicator will begin to blink.
                The radio is now in cross band repeat. When a signal is
                received on one band, it will be retransmitted onto the
                other band.

12.2    DEACTIVATE CROSS BAND REPEATER

        To return to original mode perform the following:

             1. Press and hold the FUNC key, then you will press the
                FL/PL key 4 times. After you press it the first time the
                LCD will display CLoSE. This indicates to you that cross
                band repeat has been disabled. The other 3 times that
                you press the FL/PL key will turn off the FL and PL
                indicators.  

13      FULL DUPLEX OPERATION

        The principles of Full Duplex operation is very much like a
        telephone. The idea behind this is that when you are
        talking (let's say) on 2 meters you will hear the
        transmission from the other station on the 440 band. He
        will hear you on 2 meters.
        
        YOUR STATION                                  OTHER STATION

        TRANSMIT ON 2 METERS ------>-------->-------> RECEIVE ON 2 METERS
        RECEIVE ON 440 BAND  <-----<--------<-------- TRANSMIT ON 440 BAND

13.1    ENABLE SPEAKER FULL-DUPLEX

        Enabling the speaker will cause feedback unless an external
        earphone or headset is used.

             1. Press and hold the FUNC key, then press the * key. The
                LCD should display FL. 

             2. Press and hold the FUNC key, then press the 5 key. The
                LCD should display Fd-on. Repeat this step until the
                field indicates Fd-on.

             3. Press and hold the FUNC key, then press the FL/PL key
                repeatedly until the FL and PL indicators are absent
                from the LCD display. 

13.2    DISABLE SPEAKER SEMI-DUPLEX

        Perform the following steps:

             1. Press and hold the FUNC key, then press the * key. The
                LCD should display FL. 

             2. Press and hold the FUNC key, then press the 5 key. The
                LCD should display Fd-oF. Repeat this step until the
                field indicates Fd-oF. 

             3. Press and hold the FUNC key, then press the FL/PL key
                repeatedly until the FL and PL indicators are absent
                from the LCD display.

14      AIRCRAFT AND CELLULAR TELEPHONE MODIFICATION

        The radio will have to be opened and modified to receive
        aircraft and cellular telephone. This procedure isn't
        difficult if you take your time. If you are unsure of your
        ability to open and/or perform this mod, please find
        someone with this know how!

                               *** NOTE ***

          Don't even think of performing this modification unless you
          have the right tools and temperment. 

             1. Turn the radio off and remove the battery pack.

             2. CAREFULLY remove the 4 phillips screws on the bottom of
                the radio. These screws represent each corner of the
                bottom of the radio. 

                                Front of Radio
                      +---------------------------------+
                      |  * <- Remove these screws -> *  |
                      |                                 |
                      |  * <- Remove these screws -> *  |
                      +---------------------------------+

                          BOTTOM VIEW OF RADIO SHOWN


             3. You are about to remove the battery connector plate.
                There are wires connected to this plate. When moving the
                plate out of the way, don't pull further then you have
                to in order to see into the bottom of the radio. Locate 
|               a BRIGHT RED LOOPED WIRE. Remove or cut (tape exposed
                ends) this jumper. That's all there is folks!

|                             *** WARNING ***

|               You should be extremely careful not to cut the wrong
|               wire. You may cut the BRIGHT RED LOOPED WIRE. Don't
|               cut the pink or orange wire by mistake.

             4. Take your time and reassemble the radio. Make sure that
                during reassembly that you:

                o Don't forget to place long tension arm (part of the
                  battery connector plate) into the battery lock clip
                  located on the same side of the radio as the PTT
                  switch.

             REMEMBER, be patient and take your time. Never force
             anything together! It came apart easily, it should go back
             together that way. 

             5. Reset the radio (Section 9.3) and enjoy a hot airband
                receiver. You will be able to enter a frequency range
                from 108-142.995. The receiver will actually begin to
                receive around 110 MHz.  Another way to gain access into
                the airband is, press the "FUNC" button while pressing
                the "VHF" key. 

|                        *** CELLULAR RECEIVE ***

|               After you modified your DJ-580 for Airband, you also
|               enabled cellular telephone reception. To receive
|               cellular telephone, you can enter the frequency directly
|               from the keypad or press the "FUNC" button while
|               pressing the "UHF" key. The STEP key in cellular regions
|               will only allow increments of 10, 12.5, 20 and 25 kHz.

                                 *** NOTE ***
 
             If you see a second decimal point blink in the frequency
             displayed, this means that the PLL circuitry isn't locked.
             Example:  108.0.0
                            ^____ This decimal point will blink.
