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 defec-
tive, 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.

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 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 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.

1.7 Safety Precautions
1.8 Jumper Settings
This section provides instructions on how to configure your motherboard by setting
the jumpers. It also includes the motherboard default settings and your options for
each jumper.
1.8.1 How to set jumpers
You can configure your motherboard to match the needs of your application by set-
ting jumpers. A jumper is a metal bridge that closes an electrical 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” (or turn on) a jumper, you connect the pins
with the clip. To “open” (or turn off) a jumper, you remove the clip. Sometimes a
jumper consists of a set of three pins, labeled 1, 2, and 3. In this case you connect
either pins 1 and 2, or 2 and 3. A pair of needle-nose pliers may be useful when set-
ting jumpers.
Warning! Always completely disconnect the power cord from your chassis when-
ever you work with the hardware. Do not make connections while the
power is on. Sensitive electronic components can be damaged by sud-
den power surges. Only experienced electronics personnel should open
the PC chassis.
Caution! Always ground yourself to remove any static charge before touching the
motherboard. Modern electronic devices are very sensitive to static
electric discharges. As a safety precaution, use a grounding wrist strap
at all times. Place all electronic components on a static-dissipative sur-
face or in a static-shielded bag when they are not in the chassis.
Caution! The computer is provided with a battery-powered Real-time Clock cir-
cuit. There is a danger of explosion if battery is incorrectly replaced.
Replace only with same or equivalent type recommended by the manu-
facturer. Discard used batteries according to manufacturer’s instruc-
tions.
Caution! There is a danger of a new battery exploding if it is incorrectly installed.
Do not attempt to recharge, force open, or heat the battery. Replace the
battery only with the same or equivalent type recommended by the man-
ufacturer. Discard used batteries according to the manufacturer’s
instructions.

Chapter 1 Hardware Configuration
1.8.2 CMOS clear (JCMOS1) and Intel® ME update (JME1)
The AIMB-788 motherboard contains a jumper that can erase CMOS data and reset
the system BIOS information. Normally this jumper should be set with pins 1-2
closed. If you want to reset the CMOS data, set JCMOS1 to pins 2-3 closed for just a
few seconds, and then move the jumper back to pins 1-2 closed. This procedure will
reset the CMOS to its default setting.
1.8.3 Watchdog timer output and OBS alarm (JWDT1+JOBS1)
The AIMB-788 contains a watchdog timer that will reset the CPU. This feature means
the AIMB-788 will recover from a software failure or an EMI problem. The JWDT1
jumper settings control the outcome of what the computer will do in the event the
watchdog timer is tripped.
The 2-pin OBS alarm header (JOBS1) enables/disables hardware monitor alarm
functions.
