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