BATTERY INSTALLATION
BATTERY SAVER MODE
Your FR-540 has a unique circuit designed to dramatically extend
the life of its batteries. After 10 seconds of inactivity, the FR-540 will
switch to battery saver mode. While in battery saver mode, the battery
saver mode indicator (
) is present on the display, and the trans-
ceiver will remain ready to receive any incoming transmissions while
the battery saver mode is active. Pressing any of the buttons, except
the up, down or power buttons, will exit the battery saver mode and
illuminate the display.
CAUTION:
Your FR-540 requires three “AAA” alkaline cells or
three 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 the
its grooved section. Observe the polarity symbols
inside the battery tray when installing the batteries.
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.
