AC Plug Adaptor (1)
(E03-0115-05)
Use to adapt the plug on the
power cord to the shape of the
wall outlet.
(Accessory only for regions where
use is necessary.)
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 key.
For the U.S.A. and Canada
With the power cord plugged in, turn the POWER key
OFF. Then, while holding down the ON/STANDBY
key, press POWER.
For other countries
