PRODUCT SAFETY NOTICE
Each precaution in this manual should be followed during servicing. Components identified with the IEC symbol
diagram designated components in which safety and performance can be of special significance. When replacing a component identified by
the replacement 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.
