1. CtCss CoDe seleCtion
The Continuous Tone Coded Squelch System (CTCSS) is a Squelch
quieting system that allows groups of users to share the same
channel without disturbing each other. It uses 1 of 38 low
frequency tones to open and close the Squelch on the radio. The
CTCSS codes do not prevent others from hearing your transmission.
They simply provide you with a quieter channel by preventing you
from hearing transmissions that are not using the same code as you
and are therefore not directed at you.
NOTE: To communicate with other UHF radios using CTCSS, all
radios you wish to communicate with must be switched to the
same channel and have the same CTCSS code selected. If you wish
to receive signals from UHF radios that are not using CTCSS you
will need to either disable CTCSS on that channel or set the CTCSS
code to ‘
oF ‘ as described in the following ‘note’.
To Select a CTCSS Code
From the ‘Standby’ mode:
1. Select the required channel using the or keys.
2. Press the MODE key ONCE (1) to select the CTCSS setting mode.
‘CTC’ will flash on the display.
3. Press the or keys to select the required CTCSS code. (A list
of available codes is shown in the chart on page 12).
NOTE: To turn CTCSS off on this channel, set the CTCSS code to ‘oF‘
4. Press the MODE or PTT key momentarily to confirm and store
your selection.
