- From GMRS/FRS standby mode, press the MODE button (12) once, or
until the channel number flashes.

nel number.

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 22 channels.
To change the CTCSS Sub-channel:
- From GMRS/FRS 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 (01-38).
- 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/FRS units, they must be
switched to the same channel and CTCSS subcode. To commu-
nicate with other GMRS/FRS 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.
