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