EPLACEMENT
A 3-V Type CR2032 Lithium Battery (BT5001) is
located on the CNTL UNIT board (underside) of the
transceiver. This maintains the memorized data in your
radio. Battery life is normally greater than five years,
however, should replacement be needed, perform the
following steps:
With the carrying handle and top and bottom cov-
ers removed, note the location of the battery. Using
your finger, slide the battery inward (you will feel slight
pressure by the mounting spring), then slightly pry it
up and outward so that it ejects freely through the slots
in the battery holder.
Carefully note battery polarity with the positive (+)
side facing upward, and battery-type information. In-
stall the replacement battery in the reverse manner.

The rear panel memory BACKUP switch is normally
kept in the “ON” position to ensure your memorized
data is maintained (by a small amount of power from
the lithium battery) when the radio is off, or the DC
power source is removed.
¦ If you do not plan to operate your radio for ex-
tended periods of time, slide this switch to the
“OFF” position to conserve battery life.
¦ Ensure the radio is on when sliding the switch
back to the “ON” position, as this reduces the
initial current demand on the battery by the
radio’s circuits from an un-powered state.
Note: Memorized settings are lost and the radio
returns to factory default settings when turning off the
backup battery.
Miscellaneous
CAUTION
Danger of explosion if battery is incorrectly re-
placed. Replace only with the same or equivalent
type.
