VOLTAGE AND FUSING VARIATION
You will find the line voltage selector switch on rear panel. This switch has positions for 110V, 12OV, 22OV and 240V power
sources.
,/ffi__ro"*",
Before your model is shipped from the factory, the switch is set to the power requirements of the destination; nevertheless, you should check that it is set properly before plugging the power cord into the AC outlet. lf 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. Unscrew the fuse cap with a Phillips screwdriver, then take out the fuse and plug. 2. Re-install the plug with its cutaway section exposing the correct voltage indication as shown in the illustration below' 3. Refer to the table and install a replacement fuse (provided
as an accessory).
