Return & Repair Support

Before submitting an RMA request, you are highly recommended to contact our Technical Support Group first. Some issues can potentially be resolved without sending the material back to UCAS.

Please ensure that your failure report provides sufficient information so that our technicians will understand the error. If you are uncertain if the failure report is sufficient, or if there is a concern that the observed failure may not be caught by our standard factory test for the card or system, we strongly suggest you discuss the issue with our Technical Support Group first. This will avoid a product potentially being returned back to you as 'no fault found.


  • 1、Please request a Return Material Authorization number prior to returning material to UCAS by telephone at +86-10-62566794 or by email at and provide information about the defect or impairment of performance. This number must be attached to the equipment sent      back for repair.
  • 2、After receiving your RMA number, please prepare your package for shipment. If available, return the product in the original UCAS packaging. If no longer available, use a box large enough to allow for adequate cushioning material    on all sides of the equipment. To properly cushion the contents of your package, wrap each item separately. Use proper electrostatic discharge (ESD) precautions. Do not include any accessory pieces such as mounting brackets, power cords or software.
  • 3、When shipping a package: RMA number MUST be clearly visible on the outside of the package(s) and packing slip(s) for efficient customs clearance. Assets received without an RMA number will be immediately returned at the originating shipper’s expense. Please ship your asset(s) to the UCAS designated address.
  • 4、All inbound shipments must specify the shipping terms as “Prepaid Door-to-door, DDP Incoterms 2010” as noted in the terms and conditions of the RMA      request form. Failure to comply will result in unnecessary processing delays and all shipping charges charged back to the cus tomer.      Additionaladministration fees may also apply.
