Resetting the MicrocomputerThe microcomputer may malfunction (unit cannot be operated, orshows an erroneous display) if the power cord is unplugged while thepower is ON, or due to some other external factor. If this happens,execute the following procedure to reset the microcomputer andreturn the unit to its normal operating condition. Please note that resetting the microcomputer will clear the contentsof the memory and return the unit to the state it was in when it leftthe factoryUnplug the power cord from the wall outlet, thenplug it back in while holding down the POWER key.For the U.S.A. and CanadaWith the power cord plugged in, turn the POWER keyOFF. Then, while holding down the ON/STANDBY key, press POWER.For other countriesMemory 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 3 days.
