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