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
!!!
, use only 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.
