LINE VOLTAGE SELECTOR SWITCH

Only multi-voltage models are provided with this
switch. U.S.A., Canadian, European, U.K., and
Australian models are not provided with this switch.
You will find the line voltage selector switch on the rear panel.
This switch has positions for 110 V, 120 V, 220 V and 240 V
power sources. Before your model is shipped from the fac-
tory, the switch is set to the power requirements of the
destination; nevertheless, you should check that it is set pro-
perly 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. Before adjusting disconnect the power cord.
1. Provide yourself with a medium size flat tip 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.
