Product Warranty
Advantech warrants to you, the original purchaser, that each of its prod-
ucts 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 that 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 instal-
lation. Advantech assumes no liability under the terms of this warranty as
a consequence of such events.
Because of Advantech high quality-control standards and rigorous test-
ing, 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:
Step 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.
Step 2. Call your dealer and describe the problem. Please have your man-
ual, product, and any helpful information readily available.
Step 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.
Step 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 prod-
uct returned without proof of the purchase date is not eligible for
warranty service.
Step 5. Write the RMA number visibly on the outside of the package and
ship it prepaid to your dealer.

1.3 Safety Precautions
The following sections tell how to make each connection. In most cases,
you will simply need to connect a standard cable.
Warning! Always disconnect the power cord from your
chassis whenever you are working on it. Do not
connect while the power is on. A sudden rush of
power can damage sensitive electronic compo-
nents. Only experienced electronics personnel
should open the chassis.
Caution! Always ground yourself to remove any static
electric charge before touching UNO-2171. Mod-
ern electronic devices are very sensitive to static
electric charges. Use a grounding wrist strap at
all times. Place all electronic components on a
static-dissipative surface or in a static-shielded
bag.
