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 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 televi-
sion 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 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.
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.

Introduction
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 dis-
charge can damage computer components without causing any signs of physical
damage. You must take extra care in handling them to ensure against electro-
static 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 compo-
nents, contacts or connections.
5. Avoid touching the pins or contacts on all modules and connectors. Hold
modules or connectors by their ends.
Important:
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 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 requiring 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 instal-
lation 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 manufac-
turer.
• Dispose of used batteries according to local ordinance.
