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 en-

abled) 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 Fed-

eral 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 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 an

tennaisatleast1inch(2.5centimeters)fromyourbody when

transmitting.Useonlythesupplied antenna. Do not use your

transceiver with a damaged antenna. Unauthorized anten-

nas, modifications, or attachments could damage the trans-

mitter 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 GMRS600SCH radio transceiver for prolonged periods

of time in direct sunlight or temperatures below -4°F(-20°C) or above

140°F (60°C). 3

Li-ion batteries. Only Audiovox approved rechargeable batteries should

be recharged in the radio transceiver using the charging accessories.

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.
