4-4-1. Microprocessor Memory back-up
A lithium battery is contained in this transceiver to
retain memory. Tuning OFF the POWER switch ,
disconnecting the power cable or an intermittent
power failure will not erase the memories. The battery
life is estimated at 5 years. When the battery has been
exhausted erroneous information might appear in the
display.
Lithium battery replacement should be performed by
an authorized KENWOOO service facility, or your
authorized KENWOOD dealer. This equipment contains
CMOS circuitry and can be damaged by improper
replacement procedures.
