GENERAL INFORMATION
1-6
When returning equipment for repair, it is also
recommended that you use a PO number or some other
reference number on your paperwork in case you need
to call the repair lab about your unit. These numbers
are referenced on the repair order and make it easier
and faster to locate your unit in the lab.
Return Authorization (RA) numbers are not
necessary unless you have been given one by the Field
Service Department. RA numbers are required for
exchange units or if the Field Service Department
wants to be aware of a specific problem. If you have
been given an RA number, reference this number on
the Factory Repair Request Form sent with the unit.
The repair lab will then contact the Field Service
Department when the unit arrives. For additional
information on factory service, the Depot Service
Department can be contacted at the following E-mail
address:
