MANUAL!
NOTICE
For servicing RZ-1500, please refer to service manual for the
RZ-1000 with this manual, since most of the parts and circuits
employed in RZ-1500 are in common with the RZ-1000.
On the parts list, the changed parts are specified by "®" mark on
top of the Stock No. ,
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.

CAUTION
1. Parts identified by the Z\ 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 appli-
ance to the customer.
