CPU Resetting and Memory Backup
The FT -1 OO's memory data is maintained, even when DC power is turned off, via a lithium
backup battery with an estimated lifetime
of approximately five years. No data essential to
the fundamental operation
of the transceiver is stored in "volatile" memory, so when the
battery's voltage ultimately is depleted the transceiver will not be disabled; you will
just
observe that the memories will have disappeared.
In some cases
of erratic operation, it may be advisable to reset the microprocessor to it
factory default condition, so as to determine whether or not a part failure has caused im-
proper action, as opposed to some operational error.
This section describes the procedures for tow types
of microprocessor resets.
RESET PROCEDURES

I. Tum the transceiver Off.
2. Press and hold in the [HOME] and [FUNC] keys; while holding them in, press and
hold
in the [PWR] switch for 1h second to tum the transceiver On.
3. Release all keys; the reset procedure is now complete.
To reset the VFO and memories, but leave the customized MENU settings as you have
set them:
1. Tum the transceiver Off.
2. Press and hold in the [DSP] and [LOCK] keys; while holding them in, press and
hold
in the [PWR] key for Y2 second to tum the transceiver On.
3. Release all keys; the reset procedure is now complete.
The suggestions below may help you recover from commonly-encountered operational
