FCC and DOC Statement on Class B
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reason-
able protection against harmful interference when the equipment is operated in a residential
installation. This equipment generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is encour-
aged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected.
• Consult the dealer or an experienced radio TV technician for help.

Important:
Static Electricity Precautions
It is quite easy to inadvertently damage your PC, system board, components or devices even
before installing them in your system unit. Static electrical discharge can damage computer
components without causing any signs of physical damage. You must take extra care in han-
dling them to ensure against electrostatic build-up.
1. To prevent electrostatic build-up, leave the system board in its anti-static bag until you are
ready to install it.
2. Wear an antistatic wrist strap.
3. Do all preparation work on a static-free surface.
4. Hold the device only by its edges. Be careful not to touch any of the components, contacts
or connections.
5. Avoid touching the pins or contacts on all modules and connectors. Hold modules or con
nectors by their ends.
Safety Measures
To avoid damage to the system:
• Use the correct AC input voltage range.
To reduce the risk of electric shock:
• Unplug the power cord before removing the system chassis cover for installation or servic-
ing. After installation or servicing, cover the system chassis before plugging the power cord.
Battery:
• Danger of explosion if battery incorrectly replaced.
• Replace only with the same or equivalent type recommend by the manufacturer.
• Dispose of used batteries according to local ordinance.
Electrostatic discharge (ESD) can damage your processor, disk drive and other components.
Perform the upgrade instruction procedures described at an ESD workstation only. If such a sta-
tion is not available, you can provide some ESD protection by wearing an antistatic wrist strap
and attaching it to a metal part of the system chassis. If a wrist strap is unavailable, establish
and maintain contact with the system chassis throughout any procedures requiring ESD protec-
tion.

more information about the standard package in your region, please contact your dealer or
sales representative.
Safety Precautions
• Use the correct DC input voltage range.
• Unplug the power cord before removing the system chassis cover for installation or servic-
ing. After installation or servicing, cover the system chassis before plugging the power cord.
• Danger of explosion if battery incorrectly replaced.
• Replace only with the same or equivalent type recommend by the manufacturer.
• Dispose of used batteries according to local ordinance.
• Keep this system away from humidity.
• Place the system on a stable surface. Dropping it or letting it fall may cause damage.
• The openings on the system are for air ventilation to protect the system from overheating.
DO NOT COVER THE OPENINGS.
• Place the power cord in such a way that it will not be stepped on. Do not place anything on
top of the power cord. Use a power cord that has been approved for use with the system
and that it matches the voltage and current marked on the system’s electrical range label.
• If the system will not be used for a long time, disconnect it from the power source to avoid
damage by transient overvoltage.
• If one of the following occurs, consult a service personnel:
- The power cord or plug is damaged.
- Liquid has penetrated the system.
- The system has been exposed to moisture.
- The system is not working properly.
- The system dropped or is damaged.
- The system has obvious signs of breakage.
• The unit uses a three-wire ground cable which is equipped with a third pin to ground the
unit and prevent electric shock. Do not defeat the purpose of this pin. If your outlet does
not support this kind of plug, contact your electrician to replace the outlet.
• Disconnect the system from the DC outlet before cleaning. Use a damp cloth. Do not use
liquid or spray detergents for cleaning.

Connecting Cables to Terminal Blocks
Important:
When installing the touch panel PC, make sure the power is off. Failure to turn off, may cause
severe damage to the system.
1. Insert the cable end of the power adaptor to the terminal block. To firmly fix the cable into
the terminal block, use a screwdriver to clamp down the wires to the screw that is in the
terminal block.
2. Plug the terminal block into the DC-in connector and then tighten the screws to secure the
terminal block in place.

Important:
Electrostatic discharge (ESD) can damage your board, processor, disk drives, add-in
boards, and other components. Perform installation procedures at an ESD workstation
only. If such a station is not available, you can provide some ESD protection by wear-
ing an antistatic wrist strap and attaching it to a metal part of the system chassis. If
a wrist strap is unavailable, establish and maintain contact with the system chassis
throughout any procedures requiring ESD protection.
Important:
When the Standby Power LED lit red, it indicates that there is power on the system
board. Power-off the PC then unplug the power cord prior to installing any devices.
Failure to do so will cause severe damage to the motherboard and components.

USB 2.0/1.1 Ports
USB allows data exchange between your computer and a wide range of simultaneously acces-
sible external Plug and Play peripherals.
The system board is equipped with two onboard USB 2.0/1.1 ports (USB 4-5). The 10-pin con-
nector allow you to connect two additional USB 2.0/1.1 ports (USB 6-7). The additional USB
ports may be mounted on a card-edge bracket. Install the card-edge bracket to an available
slot at the rear of the system chassis and then insert the USB port cables to a connector.
LAN Port
The LAN port allows the system board to connect to a local area network by means of a
network hub.
