Product Warranty 
Advantech warrants to you, the original purchaser, that each 
of its products will be free from defects in materials and 
workmanship for one year 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
