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 GMRS121-2 radio transceiver for prolonged periods of
time in direct sunlight or temperatures below -4°F(-20°C) or above
140°F (60°C).

The following guidelines will improve performance and provide longer
operating times for the GMRS121-2:
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.
