PRODUCT SAFETY NOTICE
Each precaution in this manual should be followed during
servicing. Components identified with the IEC symbol A

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.
