CTCSS sub-audio tone setting
The CTCSS sub-tones, are code numbers (from 1 to 38) that can be added to
the first 8 channels in order to create a new private channel. You can add up
to 38 codes to the channels named from P1 to P8. For example if you add the
CTCSS sub-tone “27” to the channel “P3” you will obtain the new channel
“P327” that will be able to communicate to other transceivers only if they will
be set on the same channel and sub tone.
To activate 38 dierent CTCSS sub-tones follow these steps:
1. Turn on the radio.
2. Press the Menu button and select with the ▲/▼ buttons one of the 8
channels (from P1 to P8).
3. Press twice the Menu button until the display shows the selected channel
with the flashing two CTCSS sub-tone digits (on the right of the channel)
4. Select with the ▲/▼ buttons the desired CTCSS tone (from 1 to 38).
5. To confirm the setting press PTT.
Now the radio transmits and receives using the programmed CTCSS sub-
tone. If you don’t want to use any CTCSS tone, select “oF”.
CTCSS tones displayed on the LCD
When you activate a CTCSS sub-tone, from P1 to P8, you can see the tone
on the right side of the channel. For the other channels (from 9 onwards) the
CTCSS sub-code is pre-programmed and then “hidden”.
Keypad beep o
Everytime you press any button, you will hear a beep sound. To deactivate it
press Menu 4 times. Then select “oF” with the ▲/▼ controls and confirm your
selection by pushing PTT. To enable the beep again, repeat the same procedure
and select “ON”.
MON/SCAN
Monitor function
When this feature is activated, the radio can receive very low and weak signals.
This is very useful when you need to talk but the distance is as far as the ma-
ximum range possible; with the monitor feature you can extend the coverage
of the radio.
The disadvantage is the reception of loud background noises.
