SHOCK, FIRE HAZARD SERVICE TEST :

CAUTION : After servicing this appliance and prior to returning to customer, measure the resistance between either primary

AC cord connector pins (with unit NOT connected to AC mains and its Power switch ON), and the face or Front Panel of

product and controls and chassis bottom.

Any resistance measurement less than 1 Megohms should cause unit to be repaired or corrected before AC power is applied,

and veried before it is return to the user/customer.

Ref. UL Standard No. 60065.

NOTE ON SAFETY :

Symbol z Fire or electrical shock hazard. Only original parts should be used to replaced any part marked with symbol z .

Any other component substitution (other than original type), may increase risk of re or electrical shock hazard.

steel wool, scourging powders or harsh chemical

agents (e.g., lye solution), alcohol, thinner, benzine,

insecticide or other volatile substances as these wil

mar the ﬁ nish of the equipment. Likewise, never

use cloths containing chemical substances. If the

equipment get dirty, wipe the external surfaces with

a soft, lint-free cloth.

If the equipment becomes heavily soiled:

• dilute some washing up liquid in water, in a ratio of

one part detergent to six parts water.

• dip a soft, lint free in the solution and wring the it is

damp.

• wipe the equipment with the damp cloth.

• dry the equipment by wiping it with a dry cloth.

REPAIRS

Only the most competent and qualified service

technicians should be allowed to service the

factory-trained warranty station personnel have

the knowledge and special facilities needed for
