CAUTION

i 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 charac-
teristics recommended by the manufacturer.

2. Make leakage-current or resistance measurements
to determine that exposed parts are acceptably 'm-
sulated from the sUpply circuit befOre returning the
appliance to the customer.
