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 (01-38) 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 from the same main channel). Since there are 38 CTCSS Sub-channels for each main channel, a different subcode may be se- lected for each of the 22 channels.

To change the CTCSS Sub-channel:

-From GMRS/FRS standby mode, press the MODE Button twice; a flash ing 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 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.
