-Then press the Up or Down button to select the desired sub-channel for use.

-Press the Power On/Off 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.
