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.
