Resetting the Microcomputer
·
For U.S.A. and Canada
For other countries
If the microcomputer may malfunction (unit cannot be operated,
or shows an erroneous display) if the power cord is unplugged
while the power is ON, or due to some other external factor. If
this happens, execute the following procedure to reset the
microcomputer and return the unit to its normal operating
condition.
Please note that resetting the microcomputer will clear the contents
of the memory and returns the unit to the state it was in when it left
the factory.
Unplug the power cord from the wall outlet, then plug it back in
while holding down the POWER key.
With the power cord plugged in, turn the POWER key OFF. Then,
while holding down the ON/STANDBY key, press POWER.

This unit works backup by microprocessor if power is off. The
microprocessor carries out the power-off-checking by 1ms. It
sets up the initialized data if the backup data is destroyed.
Also plug in and out the power cord from the outlet with
pressing the power switch for initialization.
