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:
