1.9 IF A PROBLEM ARISES...
JDT products are designed for long life and failure-free operation. If a problem arises, factory service is
available. Contact the Customer Service Department before returning equipment. A service representative may
suggest a solution eliminating the need to return equipment.
1.9.1 FACTORY REPAIR
Component level repair is not recommended on the DM3474 Transceiver. Surface mount technology is used
to install many components that require specialized training and equipment to service board level components.
JDT’s factory is best equipped to diagnose problems and make component level repairs.
When returning equipment for repair, fill out a Factory Request Form for each unit to be repaired regardless of
warranty status. These forms are available free of charge by calling Customer Service (see Section 1.6). Describe
the problem in the space provided and note any prior physical damage to the equipment. Include a form in the
shipping container with each unit. Your phone number and contact name are important. There are times when
technicians have specific questions that need to be answered in order to identify the problem and repair the
equipment.
When returning equipment for repair, use a reference number on your paperwork in case you need to call
Customer Service about your unit. That number is referenced on the repair order to make it easier to locate your
unit in the lab.
Return authorization (RA) numbers are not necessary unless you have been given one by the Customer
Service Department. They require RA numbers for exchange units or if they want to be aware of a specific
problem. If you have been given an RA number, reference this number of the Factory Repair Request Form sent
with the unit. The repair lab will contact the Customer Service Department when the unit arrives.
