Product Warranty (2 years)
Advantech warrants 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 that have been repaired or altered by
persons other than repair personnel authorized by Advantech, or products that 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
customers never need to use our repair service. If an Advantech product is defective,
it will be repaired or replaced free of charge during the warranty period. For out-of-
warranty repairs, customers will be billed according to the cost of replacement mate-
rials, service time, and freight. Please consult your dealer for more details.
If you believe your product to be defective, follow the steps outlined below.
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 displayed when the prob-
lem 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 a return merchandise authori-
zation (RMA) number from your dealer. This allows us to process your return
more quickly.
4. Carefully pack the defective product, a completed Repair and Replacement
Order Card, and a proof of purchase date (such as a photocopy of your sales
receipt) into a shippable container. Products returned without a proof of pur-
chase date are not eligible for warranty service.
5. Write the RMA number clearly on the outside of the package and ship the pack-
age prepaid to your dealer.

Safety Instructions
1. Read these safety instructions carefully.
2. Retain this user manual for future reference.
3. Disconnect the equipment from all power outlets before cleaning. Use only a
damp cloth for cleaning. Do not use liquid or spray detergents.
4. For pluggable equipment, the power outlet socket must be located near the
equipment and easily accessible.
5. Protect the equipment from humidity.
6. Place the equipment on a reliable surface during installation. Dropping or letting
the equipment fall may cause damage.
7. The openings on the enclosure are for air convection. Protect the equipment
from overheating. Do not cover the openings.
8. Ensure that the voltage of the power source is correct before connecting the
equipment to a power outlet.
9. Position the power cord away from high-traffic areas. Do not place anything over
the power cord.
10. All cautions and warnings on the equipment should be noted.
11. If the equipment is not used for a long time, disconnect it from the power source
to avoid damage from transient overvoltage.
12. Never pour liquid into an opening. This may cause fire or electrical shock.
13. Never open the equipment. For safety reasons, the equipment should be
opened only by qualified service personnel.
14. If any of the following occurs, have the equipment checked by service person-
nel:
–The power cord or plug is damaged.
–Liquid has penetrated the equipment.
–The equipment has been exposed to moisture.
–The equipment is malfunctioning, or does not operate according to the user
manual.
–The equipment has been dropped and damaged.
–The equipment shows obvious signs of breakage.
DISCLAIMER: These instructions are provided according to IEC 704-1 standards.

Safety Precautions - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from
damage.
To avoid electrical shock, always disconnect the power from the PC chassis
before manual handling. Do not touch any components on the CPU card or
other cards while the PC is powered on.
Disconnect the power before making any configuration changes. A sudden rush
of power after connecting a jumper or installing a card may damage sensitive
electronic components.

2.3 Jumpers
2.3.1 Jumper Description
Cards can be configured by setting jumpers. A jumper is a metal bridge used to close
an electric circuit. It consists of two metal pins and a small metal clip (often protected
by a plastic cover) that slides over the pins to connect them. To close a jumper, you
connect the pins with the clip. To open a jumper, you remove the clip. Sometimes a
jumper will have three pins, labeled 1,2 and 3. In this case you would connect either
pins 1 and 2, or 2 and 3.
The jumper settings are schematically depicted in this manual as follows.
A pair of needle-nose pliers may be helpful when working with jumpers. If you have
any doubts about the best hardware configuration for your application, contact your
local distributor or sales representative before you make any changes.
Generally, you simply need a standard cable to make most connections.
2.3.2 Jumper List
Warning! To avoid damaging the computer, always turn off the power supply
before setting jumpers.
