MICROPROCESSOR MEMORY BACKUP
This transceiver uses a lithium battery to retain the
user-specified memory items. Switching the power
OFF will not erase the Menu Setups or memory
channels. Lithium battery life is approximately 5
years.
If you find the transceiver powers-up with default
settings, and channel and VFO data is erased, have
the lithium battery replaced. Contact an authorized
KENWOOD Service Facility or dealer.
MEMORY CHANNEL DATA
This transceiver has numerous memory channels for
different purposes as follows:
* 50 simplex channels
* 49 split-frequency channels
* 1 Scan Limits channel
* 1 Call channel
