Return Procedures-2

Factory Repair

To return equipment for factory repair, call the Logistics Administration Group at
(508) 261-4495, for return authorization and instructions. When you call, you will be
given a Return Material Authorization (RMA) control number. Mark this number
clearly on the shipping container for ease of identification and faster service. The
RMA control number provides a convenient tracking reference for both parties.
Please have the following information available for each piece of equipment you
return:

• Product name and description

• Serial number

• Failure symptoms

Packaging
Guidelines for
Equipment Return

Data communications equipment or parts that are to be returned to Motorola for any
reason must be properly packaged to prevent damage in shipment and handling.

If the original packing material and shipping container are available, reuse these
items to return equipment. If these items are not available, it is your responsibility to
package the contents in a manner that protects the equipment from damage during
normal shipping and handling. Responsibility for damage to equipment during
transit must be resolved between you and the carrier. The Logistics Administration
group can provide you with specific packaging instructions upon request.
