Monitor (MON)
The Monitor function excludes (opens) the squelch in order to listen to signals
that are too weak to keep the squelch permanently opened.
Press MON to turn it on and o.
Cloning function (COPING)
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 (cod. R73727) to both radios
2. To enter the channel clone condition, press and hold the MON button whi-
le turning on the main radio; the LCD shows ‘COPYING’.
3. Turn on the sub-radio (radio to program).
4. Press 1 on the main radio. The red led of the main radio and the green led of
the sub-radio will blink. ‘CL-OUT’ will appear on the display.
5. When the two leds do not blink anymore, the LCD of the main radio shows
‘COPYING’ and the sub-radio reboots: this means that cloning is finished.
Before using the radios, turn them o and then on.
Channel/Frequency Mode conversion (VFO/MR)
To switch between channel and frequency mode push VFO/MR.
TX 1750Hz Call Tone
Press PTT + BAND to send 1750Hz call tone. This function is useful for com-
munications through repeaters.
TX/RX Reverse function (R)
The reverse frequency function interchanges the TX frequency with RX. This
function is very helpful when you operate with a repeater; you can check whe-
ther it is possible to receive the communication from the other part without
the use of the repeater.
Note: you can turn the reverse function on when you are operating in simplex
mode (same tx and rx frequency). However it does not change the tx and rx fre-
quency.
