Channel Selection
In order to communicate with other GMRS/FRS units, both transmitting
and receiving party must be on the same frequency.
The GMRS1100-2CH 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 channels,
while channels 15-22 are assigned GMRS only channels. If an 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 chan-
nels. 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.
