SERVICE SAFETY PRECAUTIONS

1. Replacing the Fuses

CAUTION: FOR CONTINUED PROTECTION AGAINST THE RISK OF FIRE

REPLACE ONLY WITH SAME TYPE OF FUSE.

REFERENCE NO. PART NUMBER DESCRIPTION

2. Safety-check out (North American model only)

Before returning the product to the customer, make leakage current or

resistance measurements to determine that exposed parts are acceptably

insulated from the supply circuit.

Parts marked with the symbol are critical with regard to the risk of fire and

electric shock.Replace only parts recommended by the manufacturer.
