8 LITHIUM BATTERY REPLACEMENT
The IC-735 uses an advanced, highly reliable CPU with a long life
lithium battery. The purpose of the battery is to provide power to
the CPU so it retains all memory information during power failures,
or when the unit is unplugged or turned off.
The usual life of the lithium battery is approximately five years.
After five years of use, it is advisable to monitor the lithium battery
carefully and replace it if there are repeated cases of display
malfunction.
NOTE:
Battery replacement should be done by your nearest
ICOM authorized dealer or ICOM service station.
