VOX can be adjusted in 2 positions:

To disable the VOX mode, press the "menu" button till 'VOX' blinks on the
display. Select 'OF' by means of the p/q buttons and then push PTT to confirm.
Attention: the VOX function can not be used with the M48 provided headset

position if you don't use the VOX function.

› CTCSS-sub-tone setting
The CTCSS sub-tones, are code numbers (from 1 to 38) to 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, that means you can create up to 308 new
channels. 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 different CTCSS sub-tones follow these steps:
1. Turn on the radio.
2. Press the "Menu" button and select with the p/q 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 digits CTCSS sub-tone (on the right of the channel)
4. Select with the p/q buttons the desired CTCSS sub-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 "00".
Show the CTCSS-sub-tone on the LCD
When you activate a CTCSS sub-tone, from P1 to P8, the tone is visible just on the
right side of the channel. For the other channels (from 9 up) the CTCSS sub-code is
pre-programmed and then "hidden". To temporary show a pre-programmed channel
and his CTCSS sub-tone, press the "menu" button for more than 3 seconds.
