4-12. MEMORY
This transceiver incorporates a convenient 100 channel memory system that can be used to store and recall
commonly used frequencies.
4-12-1. | Microprocessor battery
A lithium battery is contained in the transceiver to retain memory. Turning off the POWER switch, disconnecting the
power cable, or a power failure will not erase the memory. The battery should last for approximately five years. When
the battery discharges, an erroneous display may appear in the display. Lithium battery replacement should be
performed by an authorized KENWOOD service facility; your KENWOOD dealer authorized service center, or the
factory, since this unit contains CMOS type circuitry.
Notes
1. When the lithium battery is replaced, the microprocessor must be reset, using the procedure in section 4-12-2.
2. When the lithium battery fails, the radio's operating system is not affected. Only information stored in memory will
be cleared.
