12、 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
13、 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.
