4.Setting the voltage selector (Worldwide models
only)
Worldwide models are equipped with a voltage selector to conform
with local power supplies. Be sure to set this switch to match the
voltage of the power supply in your area before plugging in the unit.
Determine the proper voltage for your area: 220-230 V or 120 V. If
the preset voltage is not correct for your area, insert a screwdriver
into the groove in the switch. Slide the switch all the way to the
upper (120 V) or to the lower (220-230 V), whichever is appropriate.

3. Safety-check out
(U.S.A. model only)
After correcting the original service problem, perform the
following safety check before releasing the set to the customer.
Leakage Current Check
Measure leakage current to a known earth ground(water pipe,
conduit, etc.) by connecting a leakage current tester between
the earth ground and exposed metal parts of the appliance
(input/output terminals, screwheads,metal overlays, etc.).
Plug the power supply cord directly into a 120V AC 60 Hz outlet
and turn Standby switch on. Any current meausred must not
exceed 0.5mA.
