CAUTION

1 .Parts identified by the A symbol on the schematic
diagram and the parts list are critical for safety.
Use only replacement parts that have critical
characteristics recommended by the manu-
facturer.

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.
