SERVICE SAFETY PRECAUTIONS
1.
Safety check out
(Only U.S.A. model)
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 with parts recommended by the manufacturer.
