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 microcom-
puter 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.
For the U.S.A. and Canada
Unplug the power cord from the wall outlet, then plug it
back in while holding down the POWER ON/STANDBY
key.
For other countries
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.
AC Plug Adaptor (1)
Use to adapt the plug on the
power cord to the shape of the
wall outlet.
