PRODUCT SAFETY NOTICE
Each precaution in this manual should be followed during servicing. Components identified with the
IEC symbol
in the parts list and the schematic diagram designated components in which safety
! ! !
can be of special significance. When replacing a component identified by
parts designated, or parts with the same ratings of resistance, wattage or voltage that are designated
in the parts list in this manual. Leakage-current or resistance measurements must be made to
determine that exposed parts are acceptably insulated from the supply circuit before returning the
product to the customer.
