This feature allows you to utilize the coded squelch tones (00 ~ 38) within a
main channel. This enables you to communicate with another party on the

are 38 CTCSS Sub-channels for each main channel. A different subcode
may be selected for each of the 15 channels.
To change the CTCSS Sub-channel,
- Press the Mode Button until the sub channel number or frequency is
displayed. Once a value is entered the Icon (CTC) appears and flashes
in the LCD panel.
- Press the Up Button or Down Button to choose the desired sub-channel

- Press the PTT Button to confirm your selection.

the same channel and CTCSS sub code. To communicate with
other GMRS units that do not have sub codes, switch your unit to

The CTCSS subcodes do not prevent others from hearing your
