settings are reached, a unique tone will sound.
CAUTION
SAFETY INFORMATION
Your wireless hand-held portable transceiver contains a low power
transmitter. When the PTT button is pushed (or the VOX mode is enabled)
it sends out radio frequency (RF) signals. The device is authorized to operate
at a duty factor not to exceed 50%. In August 1996, the Federal
Communications Commissions (FCC) adopted RF exposure guidelines
with safety levels for hand-held wireless devices.
Important:
To maintain compliance with the FCC' s RF exposure guidelines
hold the transmitter at least 1 inch (2.5 centimeters) from your
face and speak in a normal voice, with the antenna pointed up
and away. If you wear the handset on your body while using the
headset accessory, use only the Audiovox supplied carry clip
for this product and ensure that the antenna is at least 1 inch
(2.5 centimeters) from your body when transmitting. Use only
the supplied antenna. Do not use your transceiver with a
damaged antenna. Unauthorized antennas, modifications, or
attachments could damage the transmitter and may violate
FCC regulations.
Performance:
Your transceiver will only achieve its maximum operating range when
communicating with other transceivers across open and flat areas or
between elevated points. Normally occurring environmental factors such
as buildings, trees, terrain and weather, or interference from other radio or
electrical equipment, may have adverse effects on the transceiver's effective
range. These are not indicative of a fault condition.
Avoid placing the GMRS1072CH radio transceiver for prolonged periods
of time in direct sunlight or temperatures below -4 F (-20 C) or above
140 F (60 C).
Place the rubber cover on jacks when not in use.

Powering the transceiver:
Your GMRS1072CH radio transceiver operates on four AAA Alkaline batteries.
Alkaline batteries will provide slightly better performance than rechargeable
batteries (purchased separately). Only Audiovox approved rechargeable
batteries should be recharged in the radio transceiver using the supplied
charging accessories. This will ensure optimum performance for the
GMRS1072CH. Battery charging time is typically 16 - 20 hours.
Use of the Audiovox charging equipment with other brands of rechargeable
batteries is not recommended as battery charging times will vary. Refer to
the manufacturer's instructions for charging other brands of batteries.
Batteries
There are three methods of powering the GMRS1072CH:
1. Alkaline Batteries.
WARNING: Do not attempt to recharge Alkaline batteries.
2. Audiovox Rechargeable Ni-MH Batteries - (Rechargeable NiMH
batteries and Charging Adapter included). Use only Audiovox
approved rechargeable batteries and charging equipment when
charging batteries internal to the unit.
NOTE: To extend battery life, avoid overcharging the batteries.
3. Various Brands of Rechargeable Batteries - Use of the Audiovox
charger(s) with other brands of rechargeable batteries is not
recommended, as battery charging times will vary with different
brands of batteries. Refer to the manufacturer's instructions for
charging other brands of batteries.
Monitor/Keylock Button (2)
This button is used to to check activity on the current frequency before
transmitting. Check activity by pressing the Monitor (M) Button longer
than 2 seconds; the
icon will apppear on the display and you will hear
static if frequency is clear.
Do not transmit if you hear conversation.
Hold down the Monitor Button again longer than 2 seconds and the
icon will disapppear from the display.
The monitor function will temporarily bypass the squelch setting and play
all signals on a given channel. This feature is useful when communicating
with other parties at extreme range.
By pressing the monitor button momentarily, the keylock icon (
appear to confirm that the MODE, SCAN and channel up/down buttons
have been disabled.
Push To Talk (PTT) Button (4)
Pressing and holding this button will allow you to speak to any transceiver
that is set to the same channel and privacy code setting as yours. Hold the
transceiver approximately 1 to 2 inches from your face as you speak into
the built in microphone (9). After you have finished speaking, release the
PTT Button to allow reception of incoming signals. It is not possible to
transmit and receive at the same time. Whenever the button is pressed,
the transmit signal icon (TX) will appear in the upper left corner of the
display. Releasing the button allows the unit to revert to standby mode.
When receiving an incoming signal, the (RX) icon will appear.
The PTT Button can also be used as a two-way call ringer. Pressing the
button twice quickly will call another party on the same channel.
The transmit icon (TX) will be displayed for 3 seconds and then disappear.

WARNINGS:
Battery Care
Never attempt to charge alkaline or dry cell batteries, as batteries may
burst causing personal injury and damage to the product. If rechargeable
batteries are used, such as Nickel Metal Hydride (NiMH), use only the
supplied Audiovox-approved rechargeable batteries. Use of the Audiovox
charger (also supplied) with other brands of batteries is not recommended,
as battery charging times will vary with different brands. Refer to the
Manufacturer's instructions for charging other brands of batteries.
Battery Disposal
In general, if handled improperly, batteries pose a risk of fire or burns. Do
not disassemble, crush, puncture, short external contacts, or dispose of
the batteries in fire or water. Dispose of the batteries in a environmentally
safe manner and recycle whenever possible.
FCC WARNING
Replacement or substitution of transistors, diodes or other parts of a unique
nature, with parts other than those recommended by the manufacturer,
may cause a violation of the technical regulations of Part 15 of FCC Rules.
GMRS LICENSE:
USE OF THIS RADIO WITHIN THE UNITED STATES REQUIRES AN FCC
GMRS LICENSE. AN INDIVIDUAL 18 YEARS OF AGE OR OLDER, WHO IS
NOT A REPRESENTATAIVE OF A FOREIGN GOVERNMENT, IS ELIGIBLE

The following guidelines will improve performance and provide longer
operating times for the GMRS1072CH:
1. Do not mix old and new batteries.
2. The use of alkaline-type batteries is recommended to provide the
longest operating time.
3. Do not mix alkaline, standard (carbon-zinc) or rechargeable
batteries.
4. If the unit is not to be used for an extended period of time, remove the
batteries. Old or leaking batteries can cause damage to the unit and

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 GMRS1072CH 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. 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
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)
once; 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.
- Press the PTT button momentarily to confirm selection.
CTCSS Mode (Sub-Channel) Selection
The Coded Tone Controlled Squelch System (CTCSS) has 38 Sub-Fre-
quencies.
This feature allows you to utilize the coded squelch tones (01-38) 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 from the same main channel). Since there are
38 CTCSS Sub-channels for each main channel, a different subcode
may be selected for each of the 22 channels.
