This chapter explains the following topics:

•Theory of Operation (how the multiple channel switching system works)

•Recommended Test Equipment (the equipment required for servicing these instruments)

•Service

❍Troubleshooting (how to determine which part of the system is faulty)

❍Replaceable Parts (how to identify and order parts)

❍Assembly/Disassembly (how to remove and replace failed assemblies)

❍Adjustments (how to make any adjustments or settings required)

❍Preventive Maintenance (what service should be done as a preventive)

The assemblies used in the multiple channel controller system are static sensitive. Use anti-static techniques when performing the following procedures. For example, wear an anti-static ground strap and work at a station equipped with an anti-static mat.
