Powering the transceiver:
Your GMRS-1545 radio transceiver operates on five AA batteries. Alkaline
batteries will provide slightly better performance than rechargeable batteries.
Only Audiovox-approved rechargeable batteries can be recharged in the radio
transceiver using the optional charging stand, or the AC/DC wall charging
adapter (supplied).
Installing the batteries:
Battery installation is made more convenient when the belt clip is removed.
To do this, release the spring clip securing the belt clip to radio and slide the
belt clip downward and away from the radio body. Next, press down with the
thumb at the arrow, slide the battery cover down and lift off the battery cover.
Insert five AA batteries (alternate positive (+) ends). Position batteries in
accordance with polarities indicated by the battery tray.

The following guidelines will improve performance and provide longer
operating times for the GMRS-1545:
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.
3. Insert five AA batteries
with positive (+) end of
top, middle and bottom
batteries oriented as
shown, or insert type
NiMH rechargeable
batteries.
2. Using thumb, press
down on battery
