@ BACKUP BATTERY REPLACEMENT
A lithium battery is contained in the transceiver to retain
memory. Thus, turning off the POWER switch, discon-
necting the power cable, or a power failure will not clear
the memory. The battery should last approximately five
years. Frequent operation of the power ON/OFF switch
may lessen the life of the battery. When the battery dis-
charges, an erroneous display may appear on the DIS-
PLAY. Lithium battery replacement should be performed
by an authorized Trio-Kenwood service facility, your Trio-
Kenwood dealer, or the factory.
Note:
When the lithium battery is replaced, the microprocessor
must be reset.
@ RESETTING
To reset the microprocessor, turn on the POWER switch
with the A=B switch held pressed. Removing your finger
from the A =B switch completes the reset.
@ ACC1 jack
This jack is designed for connection of the 6-pin DIN con-
nector supplied with the optional interface unit.
