DSE Technical Support & Service Center

Our experienced technical support team quickly responds to customer needs by offering unmatched warranty and non-warranty product support through e-mail ( and phone consultations (480.515.1110). When a product requires further technical analysis, physical damage repairs, or is in need of conversion, maintenance, or upgrade, our qualified repair technicians are available at the DSE Service Center at our Scottsdale, Arizona headquarters.

Because rugged environments (chemicals, dust, liquids, extreme temperatures, shock and vibration) add undue stress to a product’s enclosure and integrated components, DSE recommends a periodic maintenance service package be run on units three (3) years and older. This package includes internal cleaning and inspection, followed by system analysis. The fee schedule is based on the product’s options, and is discounted when combined with other service center repairs on the same unit.

To start a service return or maintenance package, an RMA number must be requested. DSE will issue that number which will be associated with the unit throughout the RMA process. Include this RMA number on the outside of the shipping box, and all correspondence. Please complete the Return Materials Authorization (RMA) Request Form online
