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 GMRS602CH 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.

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

Powering the transceiver:
Your GMRS602CH radio transceiver operates on four AAA batteries. Alkaline
batteries will provide slightly better performance than the supplied
rechargeable batteries. Only Audiovox approved rechargeable batteries
should be recharged in the radio transceiver using the supplied charging
accessories. This will ensure optimum performance for the GMRS602CH.
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 GMRS602CH:
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.

Battery installation is made more convenient when the carry clip is either
rotated left or right to the horizontal position, or is removed. Simply rotate
the clip in either direction to the horizontal position. Be careful not to use
excessive force. To remove the clip, press down on the release tab
and pull the clip straight out from the radio body. Next, press down with the
thumb at the embossed arrow, slide the battery cover down and lift it away
from the compartment. Insert four AAA batteries (alternate positive ends (+)
toward the top of the transceiver, starting left-to-right.
2. Then lift cover at
bottom to open.
Remove cover.
3. Insert four AAA batteries
(positive (+) end toward
the top begining at left
side and alternating
positive terminals as
shown).
1. Using thumb,

The following guidelines will improve performance and provide longer
operating times for the GMRS602CH:
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
will void the warranty.
