LINE VOLTAGE SELECTOR SWITCH
Only multi-voltage models are provided with this
switch. U.S., Canadian, European, U.K., and Australian
models are not provided with this switch.
The line voltage selector switch is on the rear panel. Before
your model is shipped from the factory, this switch is set to
the power requirements of the destination. Check that it is set
properly before plugging the power cord into the AC outlet. If
the voltage is not properly set or if you move to an area where
the voltage requirements differ, adjust the selector switch as
follows.
1. Provide yourself with a medium-size screwdriver.
2. Insert the screwdriver into the arrow on the voltage selec-
tor, and adjust so that the tip of the arrow points to the
voltage value of your area.
