6.4 Field Repair
Some Moseley Associates equipment will have stickers covering certain potentiometers,
varicaps, screws, and so forth. Please contact Moseley Associates technical service
department before breaking these stickers. Breaking a tamperproof sticker may void your
warranty.
When working with Moseley’s electronic circuits, work on a grounded antistatic surface, wear a
ground strap, and use industry-standard ESD control.
Try to isolate a problem to a module or to a specific section of a module. Then compare actual
wave shapes and voltage levels in your circuit with any shown on the block and level diagrams
or schematics. These will sometimes allow the problem to be traced to a component.
Spare Parts Kits
Spare parts kits are available for all Moseley Associates products. We encourage the purchase
of the appropriate kits to allow self-sufficiency with regard to parts. Information about spares
kits for your product may be obtained from our sales department or technical service
department.
Module Exchange
When it is impossible or impractical to trace a problem to the component level, replacing an
entire module or subassembly may be a more expedient way to correct the problem.
Replacement modules are normally available at Moseley Associates for immediate shipment.
Arrange delivery of a module with our technical services representative. If the shipment is to be
held at your local airport with a telephone number to call, please provide an alternate number as
well. This can prevent unnecessary delays.
