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 charac-
teristics 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.
Design and specifications subject to chiinges without notice for im-
provements.
Due to local laws and regutatfons, this unit sold In some areas are not
equipped with variable voltage sdedtors.
