Product Warranty (5 years)
Advantech warrants to you, the original purchaser, that each of its products will be
free from defects in materials and workmanship for five 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 on screen 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

Safety Precaution - Static Electricity
Static electricity can cause bodily harm or damage electronic devices. To avoid
damage, keep static-sensitive devices in the static-protective packaging until the
installation period. The following guidelines are also recommended:
Wear a grounded wrist or ankle strap and use gloves to prevent direct contact to
the device before servicing the device. Avoid nylon gloves or work clothes,
which tend to build up a charge.
Always disconnect the power from the device before servicing it.
Before plugging a cable into any port, discharge the voltage stored on the cable
by touching the electrical contacts to the ground surface.
