Make sure that your local AC mains voltage matches the voltage specified on the name plate on the bottom panel. In some areas a voltage selector may be provided on the rear panel of the PSR-9000 near the power cord. Make sure that the voltage selector is set for the voltage in your area. The voltage selector is set at 240V when the unit is initially shipped. To change the setting use a slotted (“minus”) screwdriver to rotate the selector dial so that the correct voltage appears next to the pointer on the panel.
