Before transmitting on the selected channel, press the Monitor (M) Button

(2)to check the activity on that channel. If there is activity on the selected channel, change to another channel that is clear.

To change the channel:

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

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, 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). 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. If oF is displayed, press the Up or Down button to enable the CTCSS mode.

-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.
