Batteries
There are three methods of powering the GMR-GPS:

batteries and Charging Stand not included). Use only Audiovox
approved rechargeable batteries and charger 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 with other brands

of rechargeable batteries is not recommended, as battery charging times  will vary with differ
ent  brands of batteries. Refer  to the manufacturer’s instructions  for charging other brands  of

1 . The 15 channels of the GMR-GPS 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 GMR-GPS 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

(4) and speak slowly in a normal voice.

4. To increase battery life, avoid features such as  LCD backlighting for prolonged periods of

time.  Features  such as this  will reduce operating time considerably.
