5-4-1 Microprocessor Memory Back-up
This transceiver contains a lithium battery 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; either
your
authorized KENWOOD dealer or authorized service cen-
ter.

5-4-4 Memory Channel
This transceiver provides
20
Memory Channels.
(18 Memory Channels when DRU-1 installed)
In
addition to serving as a normal Memory Channel
some
of
the Memory Channels serve a dual purpose
to
specify other parameters. The functions
of
those
Memory Channels are described below .
C Memory Channel 1 is used
to
store the frequency
for
the
Priority
Alert function.
C)
Memory Channel 7
~
10 are used to store odd split
repeater data.
C)
Memory Channel
11
is used
to
store the lower
limit
for
the Programmable Band Scan function.
C) Memory Channel 12 is used to store the upper
limit
for the Programmable Band Scan function
