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
