contains service information required for the equipment described and is current as of the printing

Warranty and Service Support

Motorola offers long term support for its products. This support includes full exchange and/or repair 
of the product during the warranty period, and service/ repair or spare parts support out of warranty. 
Any "return for exchange" or "return for repair" by an authorised Motorola Dealer must be 
accompanied by a Warranty Claim Form. Warranty Claim Forms are obtained by contacting an 
Authorised Motorola Dealer.

2.1

Warranty Period and Return Instructions

The terms and conditions of warranty are defined fully in the Motorola Dealer or Distributor or 
Reseller contract. These conditions may change from time to time and the following notes are for 
guidance purposes only.

In instances where the product is covered under a "return for replacement" or "return for repair" 
warranty, a check of the product should be performed prior to shipping the unit back to Motorola. 
This is to ensure that the product has been correctly programmed or has not been subjected to 
damage outside the terms of the warranty.

Prior to shipping any radio back to the appropriate Motorola warranty depot, please contact 
Customer Resources (Please see page 2 and page 3 in this Chapter). All returns must be 
accompanied by a Warranty Claim Form, available from your Customer Services representative. 
Products should be shipped back in the original packaging, or correctly packaged to ensure no 
damage occurs in transit. 

2.2

After Warranty Period

After the Warranty period, Motorola continues to support its products in two ways. 

1.

Motorola's Radio Aftermarket and Accessory Division (AAD) offers a repair service to both 
end users and dealers at competitive prices. 

2.

AAD supplies individual parts and modules that can be purchased by dealers who are 
technically capable of performing fault analysis and repair.

NOTE

Before operating or testing these units, please read the Safety Information Section in the
front of this manual.
