Product Warranty (2 years) Advantech warrants to you, the original purchaser, that each of its products will be free from defects in materials and workmanship for two years from the date of pur- chase. This warranty does not apply to any products which have been repaired or altered by persons other than repair personnel authorized by Advantech, or which have been subject to misuse, abuse, accident or improper installation. Advantech assumes no liability under the terms of this warranty as a consequence of such events. Because of Advantechs high quality-control standards and rigorous testing, most of our customers never need to use our repair service. If an Advantech product is defec- tive, it will be repaired or replaced at no charge during the warranty period. For out- of-warranty repairs, you will be billed according to the cost of replacement materials, service time and freight. Please consult your dealer for more details. If you think you have a defective product, follow these steps: 1. Collect all the information about the problem encountered. (For example, CPU speed, Advantech products used, other hardware and software used, etc.) Note anything abnormal and list any onscreen messages you get when the problem occurs. 2. Call your dealer and describe the problem. Please have your manual, product, and any helpful information readily available. 3. If your product is diagnosed as defective, obtain an RMA (return merchandize authorization) number from your dealer. This allows us to process your return more quickly. 4. Carefully pack the defective product, a fully-completed Repair and Replacement Order Card and a photocopy proof of purchase date (such as your sales receipt) in a shippable container. A product returned without proof of the purchase date is not eligible for warranty service. 5. Write the RMA number visibly on the outside of the package and ship it prepaid to your dealer.
