Memory - Kenwood TS-850S Instruction Manual

4-11. MEMORY
The transceiver incorporates a convenient 100
channel memory that can be used to store and recall
commonly used frequencies.
4-11-1._ Microprocessor back-up lithium
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; either your KENWOOD servicing 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 4-11-2.
2. When the lithium battery fails, the radio's
operating system is not affected. Only
information stored in memory will be cleared.
4-11-2. Initial state and reset of the
microprocessor.

B. Microprocessor reset
There are two methods for resetting the
microprocessor.
1. Press and hold the A=B key and turn on the
POWER.
Caution
All user programmed memory will be erased
with this operation.
2. Press and hold the RX-A key and turn on the
power to reset all user programmed data except
the contents of the Memory Channels.

Memory Entry
1. Select the receive frequency, the mode and the
filter.
Example: 14.175MHz is selected on VFO A
2. Press the M.IN key. The radio will enter the
Memory Scroll (M.SCR) mode.
(When Memory Channel 00 is empty.)
3. Select the desired Memory Channel number.
(When Memory Channel 03 is empty.)
4. When the desired memory channel is found and
displayed, press the M.IN key again. The current
frequency, mode and filter will be stored, the
Memory Scroll mode will be canceled, and the
transceiver will return to the operating mode and
frequency that was displayed before the M.IN key
was pressed initially.
