It is hoped this will be the better of them, being the easiest to follow! o To open up the rx only up on the unit on VHF: VHF F+0 F+D o To add 320-400MHz, 400-480MHz, 820-900MHz, 900-980MHz: UHF F+L F+0 F+B F+L F+3 A o To Expand Tx/Rx coverage, do both the above in that order, then: VHF F+6 change step to 12.5MHz A F+8 F+8 F+C Tune down to 144.9875 F+0 F+D PTT F+8 F+C o To Store independent transmit/receive frequency in one channel: Enter receive frequency into dial F+D <mem number> Enter transmit frequency into dial F+D F+A F+<mem number> A o To Clear the tx assignment offset: F+D F+A <mem number>+A F+A A o To Clone one set to another: B B F+0 F+PS then key up on the set to clone from Set mode key assignments: The set mode allows a number of user parameters to be customised according to individual taste. Set mode is initiated by pressing F+0. The following are entered after going into set mode: 0 Turns off the beep tones on each keypress F+0 Sets band edge limits, i.e. 0079=100-179, 400-479. 3060=130-160 1 Changes count of paging operations tone, one beep or 5 F+1 Set tx delay on carrier drop when using as cross-band repeater 2 Enables entry of the 1kHz figure on direct keypad entry F+2 Stop scan on busy channel even if CTCSS doesn't match 3 Sets mod delay on paging Tx to either 450ms or 750ms F+3 Switch UHF bands between 300/400/800/900 4 Mutes short noises during squelch operation F+4 Keypad entry of 4 digit or 3 digit frequency 5 Turns on and off the auto power off function F+5 Pager Audio Mute (effectively disables pager) 6 Enable/Disable the rotary channel knob when keypad locked F+6 Fast tune (F+KNOB) gives either 1MHz steps, or 100kHz 7 Sets the CTCSS tone frequency F+7 Either Dual Tone Multi Frequency, or Single Tone Frequency 8 Sets the offset repeater frequency F+8 Cross Band Repeater Enable/Disable (Identified on display by a ".") 9 Changes the LAMP button into the REV button F+9 Up and Down keys either act as the knob, or as 10MHz steps.
