FOREWORD

For your convenience, all service parts, identified in this manual are available through Eiki’s normal distribution channels.

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.

"Loading the manual" means you need to wait until the file loads and becomes available for online reading. Some manuals are very large, and the time they take to appear depends on your internet speed.
