If thishappens, 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 contentsof the memory and returns the unit to the state it was in when it leftthe factory.For the U.S.A. and CanadaUnplug the power cord from the wall outlet, then plug itback in while holding down the POWER ON/STANDBYkey.For other countriesWith 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 thepower cord to the shape of thewall outlet.(Accessory only for regions whereuse is necessary.)
