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.

NOTICE

1. The symbols UL, CSA, EU, UK, SEV, SS and XX 4. Abbreviations in this service manual are as follows:
on the parts list and the schematic diagram mean followings
