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 Ficon will be displayed on the LCD
panel; otherwise, for channels 1-7 (GMRS/FRS) and 15-22 (GMRS only)
the Gicon will be displayed. Communication with Audiovox GMRS/FRS
and compatible units is possible on these 22 channels. Before transmit-
ting 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 Function button (12) until
the channel number flashes.

channel number.
- Press the PTT, Monitor or CALL button momentarily to confirm selec-
tion.
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 (1-38) within a
main channel and 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). Since there are 38
CTCSS Sub-channels for each main channel, a different subcode may
be selected for each of the 22 channels.
To change the CTCSS Sub-channel:
- From GMRS/FRS standby mode, press the Function Button twice; a
flashing oF or sub-channel number is displayed.
- Press the Up or Down button to select the desired sub-channel for
use (1-38 ).
- Press the PTT, Monitor or CALL button to confirm selection.
The CTCSS mode can be turned off by selecting the oF icon as the setting.
NOTE: To communicate with other GMRS/FRS units, they must be
switched to the same channel and CTCSS subcode. To commu-
nicate with other GMRS units that do not have subcodes, switch
your unit to the same channel with the subcode set to oF.
The CTCSS subcodes do not prevent others from hearing your
transmission. This will only allow you to ignore all traffic on a
given channel not using the same subcode.
Key Tone and Roger Beep Tone
The Roger Beep is a tone which is automatically transmitted whenever the
PTT button is released. This tone alerts the receiving party that the trans-
mission has been terminated intentionally. The key tone feature allows the
transceiver to sound a confirmation tone whenever the following keys are

128-6297

When the key tone (and Roger Beep tone) features are on, the tone icon
appears steady on the display, and the beep tones sound in response to
button activation. When the beep tones are turned off, they again be-
comeactiveautomatically after several key presses.
Channel Scan Operation
This feature allows you to monitor all channels automatically for valid
signals. While scanning, you can transmit and receive. When a signal is
received, the scan is interrupted and will return to scan mode approxi-
mately 4 seconds after reception is terminated.

Transmit Power Selection Mode
This feature permits selection of the transmitting power level to high
(1.4 watts) or low (0.5 watt). (FRS channels 1-7 operate on 0.5 Watt
only.) Using low power, the unit will have a lower transmit range, but
battery life will be increased.
NOTE: You will find that for the majority of your needs, the low-power
setting will provide adequate communications on all channels;
there should seldom be any need to use high power, except in
situations where you need absolute maximum range. Using low
power will greatly extend battery life. We suggest you experi-
ment with switching between low and high power. However,
we do recommend that you

NOTESFOR GOODCOMMUNICATION
1 . The GMRS1100-2CH 22 channels are shared on a ‘take turns’ basis.
This means other groups may be talking on any of the channels.
A common code of ethics/courtesy is to switch to another vacant
channel and not to attempt to talk over someone who is already using
the channel you first selected.
2. The GMRS1100-2CH has been designed to maximize performance
and improve transmission range in the field. To avoid interference,
it is recommended that you do not use the units closer than 5 feet
apart.
3. For best transmission results, always keep your mouth about 2-3
inches from the microphone (9) and speak slowly in a normal voice.
4. To increase battery life, avoid features such as Scan, Dual Watch and
Weather Alert. These features will reduce operating time
considerably.
Warning
•Do not operate the transceiver unless you are licensed to do so.
•Remove the batteries from the transceiver if it is not expected to be used
for long periods. This will eliminate the possibility of chemicals leaking
from the batteries and corroding the transceiver.
•Avoid exposing the transceiver to water or extremes of temperature.
•Do not use this device in or near a mining facility, which uses remotely
triggered explosives or in areas labeled “Blasting Area”. Premature or
accidental detonation may result.
•Do not attempt to modify or in any way increase the output of this
transceiver. Its output is designed to meet the legal limits set by the FCC.
•Do not use this device or change its batteries in potentially explosive
atmospheres as sparks in such areas could result in an explosion.
•Turn your transceiver off wherever posted notices restrict the use of radios
or cellular telephones. Facilities such as hospitals may use equipment
that is sensitive to RF energy. 19
