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