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
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
Department at above mentioned address.
