CAUTION:
SAFETY INFORMATION
Your wireless hand-held portable transceiver contains a power trans-
mitter. 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 guide-
lines with safety levels for hand-held wireless devices.
Important: To maintain compliance with the FCC’s RF exposure guide-
lines hold the transmitter at least 1 inch (2.5 centimeters)
from your face and speak in a normal voice, with the an
tenna 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. Unau-
thorized 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 GMRS762CH radio transceiver for prolonged periods
of time in direct sunlight or temperatures below -4°F(-20°C) or above
140°F (60°C). 3

Powering the transceiver:
Your GMRS762CH radio transceiver operates on internally installed
Li-ion batteries. Only Audiovox approved rechargeable batteries should
be recharged in the radio transceiver using the charging accessories.
This will ensure optimum performance for the GMRS762CH. Battery
charging time is typically 11 - 13 hours. Use of the Audiovox charging
equipment with other brands of rechargeable batteries is not recom-
mended as battery charging times will vary. Refer to the
manufacturer’s instructions for charging other brands of batteries.
CAUTION: Prior to initial use, make sure to fully charge the Lithium-
Ion battery; otherwise, if the battery is allowed to dis-
charge too much, battery damage could result. The
battery should be fully charged in approximately 12 hours.
