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 “oF”.
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 tempora-
ry show a pre-programmed channel and his CTCSS sub-tone, press the
“menu” button for more than 3 seconds.
