Selector
(Rear
Panel)
Asian model are equipped with a voltage selector to
conform to local power supplied.
Be sure to set this switch to match the voltage of the
power supply in your area before plugging in the unit.
Models without a voltage selector can only be used in
area where the power supply is the same as that of the
unit.

1. Determine the proper for voltage for your area : 230-
240V or 220V.
2. If the preset voltage is not proper for your area, insert
a screwdriver into the groove in the switch. Slide the
switch all the way to the right (230-240V) or to the left
(220V), which-ever is proper.
