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 purchase. 
 
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 Advantech

s high quality-control standards and rigorous testing, most of our 

customers never need to use our repair service. If an Advantech product is defective, 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.
