ADDITIONAL FUNCTIONS WHILST IN "SET MODE" While holding the [FUNC] button press the [0/SET SB] button to enter set mode. (See Section 15 in manual). Whilst still in set mode the following btttons can be pressed, together with the [FUNC] button, to provide the these functions BUTTON FUNCTION ------ -------- [3/PO] Changes band in use in extended coverage mode (UHF Only) i.e. 300 MHz / 400 MHz / 800 MHz / 900 MHz [4/FL DM] Displays a "." between 2nd & 3rd Digit. What else it does is a mystery, if anyone knows please let me know. [6/STEP] Toggles the tunning steps on the knob on top whilst [FUNC] is depressed, between 1MHz and 0.1 MHz. [8/RPT] Enables / Disables Cross band talk through mode. When Enabled a "." appears to the top right of the memory number position. [9/REV] Toggles UP and DOWN buttons between the normal steps and 10 MHz steps. [DWN/* PS] Enter cloning mode. Transfers all memory data between 2 x C520/528`s. Tune both radios to the same frequency on one of the bands. Enter cloning mode on both radios. Press PTT on hhe radio that contains the memory data, A series of DTMF tone will be heard for approx 2 minutes. The receiving radio`s memories will now be identical to the transmitting radio. 2). EXTRA MEMORY FUNCTIONS, 40 MEMORY CHANNELS or SEPARATE TX/RX FREQ`S Although the standard manual states that 20 memories are available split between VHF and UHF bands, in fact there are 2 memory channels for each memory number on the VHF and UHF bands. These can be used in 2 ways. One way is to double the number of simplex channels availible, another is to provide programable RX and TX frequencies for each memory number. a) PROGRAMMING SEPARATE RX & TX FREQUENCIES IN ONE MEMORY LOCATION 1. In VFO mode select your RX frequency 2. Press [FUNC] and [V/M ENT] buttons together 3. Press the memory number to be programmed 4. Press [V/M ENT] button to return to VFO mode 5. Select your TX frequency. 6. Press [V/M ENT] and [FUNC] buttons together 7. Press [FUNC] button together with the memory number to program "+-" Will appear in the repeater shift display to indicate that the memory channel is now in split frequency mode. Once a memory location has been put into split frequency mode it cannot be changed back to a simplex memory unless it is programmed as an extra channel (see below) or a RESET is carried out. Pressing [FUNC] and [9/REV] will cause the RX and TX frequencies to be swapped. b) PROGRAMMING EXTRA MEMORY CHANNELS, EXTENDS TO 40 MEMORIES. Program the first 10 memories on each band as per the manual. To program the additional 10 memories on each band follow the instructions below. 1. In VFO mode select the frequency required. 2. Press [FUNC] and [V/M ENT] buttons together. _ 3. Press [FUNC] and [A/CL] Buttons together. (an M will be displayed) 4. Press the memory number to be programmed To recall these extra memories. Either use the rotary tunning control in memory mode, which will now cycle through all programmed memories. Or enter memory mode and press [FUNC] and [A/CL] together and the bar will appear above "M" indicator as when it was programmed, pressing buttons 0 to 9 will then recall the extended channels. The extended memory channels can have repeater shifts and CTCSS tones programmed in to them in the normal way BUT the value of the repeater ofset and the frequency of the CTCSS tone will be the same for both of the channels stored in one memory location. i.e memory 1 and -1 will both have the same repeater ofset but if the ofset is not activated on channel -1 then it can be used as a simplex channel.
