If thishappens, execute the following procedure to reset themicrocomputer and return the unit to its normal operatingcondition. 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/STANDBY)key.For other countriesWith the power cord plugged in, turn the POWER ON/OFFkey OFF. Then, while holding down the (POWER ON/STANDBY) key, press POWER ON/OFF key.Memory back up functionPlease note that the following items will be deleted from the unitsmemory if the power cord is disconnected from the AC outlet forapproximately 1 day.
