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 micro-
computer and return the unit to its normal operating condition.
Unplug the power cord from the wall outlet, then plug it
back in while holding down the STANDBY key.
•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.
