The Whelen Repair Center will return the repaired unit, with the transportation cost prepaid by Whelen via UPS Ground to locations within the continental U.S. only.

The above warranty is between the first purchaser (ultimate user) only and Whelen Engineering Company, Inc. (manufacturer). No prior authorization is required for returning Whelen products for warranty consideration. Each Whelen product sold is covered only by the official warranty in effect at time of purchase. This warranty is not applicable to any Whelen product that has failed from damage as a result of incompatible chemicals (including de-icing or road treatment) or cleaning products; or due to abuse, misuse, improper installation, excessive voltages, or alterations to the product that affects, in the manufacturer’s judgment, intended use and service.
