Each precaution in this manual should be followed during
servicing. Components identified with the IEC symbol
1
mark in the parts list and the schematic diagram designated
2
components in which safety and performance can be of special
3
4
significance. When replacing a component identified by
5
, use only the replacement parts designated, or parts with
6
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.
