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. (Accessory only for regions where use is necessary.)
