SERVICE MANUAL

For your convenience, all service parts, identified in this manual are available through Eiki's normal distribution chan-
nels.
In addition to service part number, the generic descriptions have been given, where possible, to allow your service
technicians to substitute equivalent components which might be available from other sources.
All orders for service parts will be honored. However, in instances where generic components are considered to be
available from several common sources, as would be the case with an industry standard fuse, resistor, or semicon-
ductor, it may be more economical and expeditious to purchase the part locally.
