Incorrect battery installation can damage the unit.
The microphone / charger jack is intended for use with Audiovox
approved charging accessories only. Refer to the documentation
included with the battery charger.
Never attempt to charge alkaline batteries with the optional battery
charger.
CAUTION:
Your FR-240 requires four “AAA” alkaline cells or
four rechargeable “AAA” cells. Alkaline batteries
will provide the best performance from your
transceiver. Remove the battery cover by
rotating the belt clip away from the battery
compartment. Slide the battery cover
downward while applying pressure at its grooved
section. Observe the polarity symbols inside the
battery tray when installing the batteries.
