CTCSS Mode (Sub-Channel) Selection
The Coded Tone Controlled Squelch System (CTCSS) has 38 Sub-Frequencies.
This feature allows you to utilize the coded squelch tones (1-38) within a
main channel and enables you to communicate with another party on the
same main channel using the same subcode. (This filters out unwanted
transmissions without the same coded squelch tone). Since there are 38
CTCSS Sub-channels for each main channel, a different subcode may
be selected for each of the 22 channels.
To change the CTCSS Sub-channel:
- From GMRS/FRS standby mode, press the Function (F) Button twice;
a flashing oF or sub-channel number is displayed.
- Press the Up or Down button to select the desired sub-channel for
use (01-38 ).
- Press the PTT or PWR button to confirm selection.
The CTCSS mode can be turned off by selecting the oF icon as the setting.
NOTE: To communicate with other GMRS/FRS units, they must be
switched to the same channel and CTCSS subcode. To commu-
nicate with other GMRS units that do not have subcodes, switch
your unit to the same channel with the subcode set to oF.
The CTCSS subcodes do not prevent others from hearing your
transmission. This will only allow you to ignore all traffic on a
given channel not using the same subcode.
