Channel Selection
In order to communicate with other GMRS/FRS units, both the transmit-
ting and receiving party must be on the same frequency.
The GMRS121-2 has 22 channels (frequencies) indicated by the large
digits on the LCD display panel. Channels 1 through 7 are the shared
GMRS/FRS channels. Channels 8-14 are FRS only channels, while chan-
nels 15-22 are assigned GMRS only channels. Communication with
Audiovox GMRS/FRS and compatible units is possible on these 22 chan-
nels. Before transmitting on the selected channel, check the activity on that
channel. If there is activity on the selected channel (
icon is displayed),
change to another channel that is clear.
To change the channel:
- From GMRS/FRS standby mode, press the MODE button (8) once;
the channel number flashes.
- Press the Up Button (6) briefly to move to the next higher main chan-
nel number.
- Press the Down Button (7) briefly to move to the next lower main
channel number.
- Press the PTT button momentarily to confirm selection.

until the flashing Roger Beep icon (
