4.2 SERVICE INFORMATION
If it becomes necessary to return this unit for repair, you must first contact
Aphex for a Return Authorization (RMA number), which will need to be
included with your shipment for proper identification. If available, repack
this unit in its original carton and packing material. Otherwise, pack the
equipment in a strong carton containing at least 2 inches of padding on
all sides. Be sure the unit cannot shift around inside the carton. Include a
letter explaining the symptoms and/or defect(s). Be sure to reference the
RMA number in your letter and mark the RMA number on the outside of
the carton. If you believe the problem should be covered under the terms of
the warranty, you must also include proof of purchase. Insure your shipment
and send it to:
