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 reasonable protection against
harmful interference when the equipment is operated in a residential
installation.This equipment generates, uses and can radiate radio fre-
quency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communi-
cations. 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 encouraged to try
to correct the interference by one or more of the following meas-
ures:
• 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.
Notice:
1. The changes or modifications not expressly approved by the
party responsible for compliance could void the user's authority
to operate the equipment.
2. Shielded interface cables must be used in order to comply with
the emission limits.

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 handling them to ensure against electrostatic build-up.
1. To prevent electrostatic build-up, leave the 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 connec-
tors. Hold modules or connectors by their ends.
Important:
Electrostatic discharge (ESD) can damage your processor,
disk drive and other components. Perform the upgrade in-
struction procedures described at an ESD workstation
only. If such a station 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 requir-
ing ESD protection.
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 servicing. 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.

Parallel Port
The onboard standard parallel port (Burgundy) is for interfacing your
PC to a parallel printer.
Note:
FDD and LPT share the same channel therefore you can only
use one device at a time. Even when you are using one device
only, please do not connect a device to the other connector.
Use JP2 to select between using FDD and LPT. FDD is inter-
nally fixed in Slave mode.

Serial Ports
The system board is equipped with an onboard serial port (COM
1). It is also equipped with a 9-pin connector (COM 2) for connect-
ing an external serial port.The serial ports are RS-232/RS-485 asyn-
chronous communication ports.
To connect COM 2, please refer to the following description. The
serial port may be mounted on a card-edge bracket. Install the card-
edge bracket to an available slot at the rear of the system chassis
then insert the cable connector to COM 2. Make sure the colored
stripe on the ribbon cable is aligned with pin 1 of COM 2.
