CTCSS Mode (Sub-Channel) Selection
The Coded Tone Controlled Squelch System (CTCSS) provides 38 Sub-Fre-
quencies. This feature allows you to utilize the coded squelch tones (01–
38) within a main channel. This 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). There
are 38 CTCSS Sub-channels for each main channel. A different
subcode may be selected for each of the 15 channels.
To change the CTCSS Sub-channel:
- From GMRS standby mode, press the MODE Button twice; a flashing
oF or sub-channel number is displayed, together with the flashing
CTC icon. If oF is displayed, press the Up or Down button to enable
the CTCSS mode; the CTC icon will also flash on the display with the
flashing sub-channel number.
- Then press the Up or Down button to select the desired sub-channel
for use.
- Press the PTT button momentarily to confirm selection.
The CTCSS mode can be turned off by selecting the oF icon as the setting.
NOTE:
To communicate with other GMRS units, they must be switched to
the same channel and CTCSS subcode. To communicate 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.
