CTCSS Mode (Sub-Channel) Selection
The CTCSS provides 38 Sub-Frequencies to allow you to utilize the coded squelch
tones (00–38). In order to communicate with another party on the same main
channel and the same subcode must be used. This filters out unwanted trans-
missions without the same coded squelch tone. Since there are 38 CTCSS Sub-
channels for each main channel, a different subcode may be selected for each of
the 14 channels.

- Press the Function (F) button twice or until the sub-channel number to the
right of the main channel number begins flashing.
- Then press the Up or Down button to select the desired sub-channel for
