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: T o 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 GMRS1882CH 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 theTransceiver:

Your GMRS1882CH radio transceiver operates on four AAA Alkaline or
rechargeable batteries. Alkaline batteries will provide slightly better
performance than rechargeable batteries (supplied). Only Audiovox
approved rechargeable batteries should be recharged in the radio
transceiver using the charging accessories. This will ensure optimum
performance for the GMRS1882CH. Battery charging time is typically 6-7
hours for full charge, and 0.5-3 hours for fast charge (depending on existing
battery charge). (Refer to battery charging instructions later in this manual.)
Batteries may get warm during fast charge. Slow charging will automatically
occur after a quick charge of 75%, and may take up to 3-4 hours to achieve
an additional 20% charge. Batteries should not get warm during the slow
charge cycle. 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.

NOTES FOR GOOD COMMUNICA TION

1 . The GMRS1882CH 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 GMRS1882CH 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 and Dual
Watch. 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.

Turn your transceiver off on board aircraft when requested to do so.
Do not place your radio in front of a vehicle’s air-bag. If the air-bag

deploys, it could propel the transceiver like a projectile causing bodily
injury.
