Resetting the Microcomputer
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 return 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 ON/STANDBY
key.
For the U.S.A. and Canada
With the power cord plugged in, turn the POWER ON/
OFF key OFF. Then, while holding down the ON/STANDBY
key, press POWER ON/OFF key.
