SERVICE PROCEDURES

1. S afety-check out
After correcting the original service problem,perl'orm
the following safety check before releasing the set
to the customer:
Connect the insulating-resistance tester between the
plug of power supply cord and chassis.
SpecificationsMore than lOMohm at 500V.

2. Voltage Selector (Back panel)
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 user's area before turning the power switch on.
Voltage is changed by sliding the groove in the switch
with a screw driver to the right or left.
Confirm that the switch has been moved all the way to
the right or left before turning the power switch on.
