IN CASE OF DIFFICULTY...

WDS products are designed for long life and trouble-free operation. However, this equipment, as 
with all electronic equipment may have an occasional component failure. The following informa-
tion will assist you in the event that servicing becomes necessary.

FACTORY TECHNICAL  ASSISTANCE

Technical assistance for WDS products is available from our Customer Support Team during 
business hours (8:30 A.M.- 5:30 P.M.Beijing Time). When calling, please give the complete 
model number of the radio, along with a description of the trouble symptom(s) that you are expe-
riencing. In many cases, problems can be resolved over the telephone, without the need for 
returning the unit to the factory.

Please use the following telephone numbers for product assistance:

856-755-83849417 (Phone)

856-755-83849434 (FAX)

FACTORY REPAIRS

Component-level repair of radio equipment is not recommended in the field. Many components 
are installed using surface mount technology, which requires specialized training and equipment 
for proper servicing. For this reason, the equipment should be returned to the factory for any PC 
board repairs. The factory is best equipped to diagnose, repair and align your radio to its proper 
operating specifications.

If return of the equipment is necessary, you will be issued a Returned Material Authorization 
(RMA) number. The RMA number will help expedite the repair so that the equipment can be 
repaired and returned to you as quickly as possible. Please be sure to include the RMA number on 
the outside of the shipping box, and on any correspondence relating to the repair. No equipment 
will be accepted for repair without an RMA number.

A statement should accompany the radio describing, in detail, the trouble symptom(s), and a 
description of any associated equipment normally connected to the radio. It is also important to 
include the name and telephone number of a person in your organization who can be contacted if 
additional information is required.

The radio must be properly packed for return to the factory. The original shipping container and 
packaging materials should be used whenever possible. All factory returns should be addressed to:

When repairs have been completed, the equipment will be returned to you by the same shipping 
method used to send it to the factory. Please specify if you wish to make different shipping 
arrangements.
