PRODUCT SAFETY NOTICE

Each precaution in this manual should be followed during servin
ing. Components identified with the IEC symbol A in the parts list
and the schematic diagram designate components in which satety
can be of special significance. When replacing a component iden-
titted with A. 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 re-
sistance measurements must be made to determine that exposed
parts are acceptably insulated from the supply circuit before re-
turning the product to the customer.
