• Channel name
To switch from the frequency mode to channel mode can be done ma­nually or by means of the optional programming software PRG-10. You can also set a password for the working modes, but only by using the optional programming software: press MENU; the display shows
. Edit the password and press
MENU again. If the password is composed of a series of 0, no password must be edited to enter the working mode.
Cloning function with the optional cable cod. R73727
This function allows you to copy/transfer all data and settings from one radio to another one; the procedure is very simple and does not need a PC: just insert the two plugs of the cloning cable into the jack of the two radios.
1. Connect the optional cable R73727 to both radios.
2. Turn on the radio ‘slave’ (radio to program).
3. Press PF3 key on the radio master (radio to be copied) and turn it on
at the same.
4. The red led on the radio master starts blinking and the display shows
‘COPYING’: the cloning function is being activated. At the end, the led turns off and the display shows ‘FINISHED!’; if the red led remains steady, the cloning procedure failed.
5. On the radio slave the green led blinks while cloning and turns off
when the procedure is finished.
6. Both radios will make a reset and will be ready for use.
Battery recharge
Insert the AC plug into the 240V socket. The charger’s led starts blinking, indicating that it is in charging stand-by. Insert the transceiver or only the
