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 s witch 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 A C pow er is applied, and
verified before it is return to the user/customer.
Ref. UL Standard No. 1492.

In case of difficulties, do not hesitate to contact the Technical
