Channel Selection
In order to communicate with other GMRS units, both transmitting and
receiving party must be on the same frequency.
The GMRS7001-2 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
channels 15-22 are assigned GMRS only channels. When this device is
being used on the FRS channels, (channels 8-14), the radio will auto-
matically switch to the low power setting, which is 0.3 watts. If an FRS only
channel (8-14) has been selected, the HI or LO indicator will not be
displayed on the LCD panel; otherwise, for channels 1-7 (GMRS/FRS)
and 15-22 (GMRS only), the HI or LO indicator will be displayed. Com-
munication with Audiovox FRS and compatible units is possible on these
seven 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 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 (00–38) 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 15 channels.
To change the CTCSS Sub-channel,
