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.
