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 manufacturer.

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