CAUTION

1. Parts identified by the Asymbol on the schematic
diagram and the parts list are critical for safety.
Use only replacement parts that have critical
characteristics recommended by the manufacturer.

2. Make leakage-current or resistance measurements
to determine that exposed parts are acceptably in-
sulated from the supply circuit before returning the
appliance to the customer.
