Channel Selection
In order to communicate with other GMRS/FRS units, both transmitting
and receiving party must be on the same frequency.
The GMRS122-2CH has 22 channels (frequencies) (1-22) 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 chan-
nels,while channels 15-22 are assigned GMRS only channels.If a FRS
only channel(8-14) has been selected, the HI or LO icon will not be
displayed on the LCD panel; otherwise,for channels 1-7(GMRS/FRS)
and 15-22(GMRS only), the HI or LO icon will be displayed.
Communication with Audiovox GMRS/FRS and compatible units is possible
on these 22 channels. 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)
until the channel number flashes.
- Press the Up Button (10) briefly to move to the next higher main
channel number.
- Press the Down Button (11) briefly to move to the next lower main
channel number.
CTCSS Mode (Sub-Channel) Selection
Coded Tone Controlled Squelch System (CTCSS) with 38 Sub-Frequencies.
This feature allows you to utilize the coded squelch tones (01–38) within a
main channel. This 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.
