This equipment has been tested and found to comply with the limits for a Class A 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 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 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.

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.
Warranty
Static Electricity Precautions
1. Warranty does not cover damages or failures that are raised from misuse of the product, inability to use the
product, unauthorized replacement or alteration of components and product specifications.
2. The warranty is void if the product has been subject to physical abuse, improper installation, modification,
accidents or unauthorized repair of the product.
3. Unless otherwise instructed in this user’s manual, the user may not, under any circumstances, attempt to
perform service, adjustments or repairs on the product, whether in or out of warranty. It must be returned
to the purchase point, factory or authorized service agency for all such work.
4. We will not be liable for any indirect, special, incidental or consequential damages to the product that has
been modified or altered.
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 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 connectors by their
ends.

Safety Measures
Before Using the System
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.
Before using the system, prepare basic system components.
If the system comes as a barebone; that is, none of the key components, including processor, memory, and hard
drive has been pre-installed as part of your purchase, you will need to at least ensure a compatible counterpart
is located and installed.
You will also need a few external system peripherals intended for the use of the system, a common pool with
at least a keyboard, a mouse, and a monitor is thus suggested.

Preparation

2.1 Before You Begin
A stable and clean working environment are essential. Dust and dirt can get into components and cause a
malfunction. Use containers to keep small components separated.
Adequate lighting and proper tools can prevent you from accidentally damaging the internal components. Most
of the procedures that follow require only a few simple tools, including the following:
A Philips screwdriver
A flat-tipped screwdriver
A set of jewelers Screwdrivers
A grounding strap
An anti-static pad
Using your fingers can disconnect most of the connections. It is recommended that you do not use needle-nosed
pliers to disconnect connections as these can damage the soft metal or plastic parts of the connectors.
Before working on internal components, make sure that the power is off. Ground yourself before touching any
internal components, by touching a metal object. Static electricity can damage many of the electronic
components. Humid environment tend to have less static electricity than dry
environments.
A grounding strap is
warranted whenever danger of static electricity exists.
Computer components and electronic circuit boards can be damaged by discharges of static electricity. Working
on the computers that are still connected to a power supply can be extremely dangerous. Follow the guidelines
below to avoid damage to your computer or yourself:
Always disconnect the unit from the power outlet whenever you are working inside the case.
If possible, wear a grounded wrist strap when you are working inside the computer case. Alternatively,
discharge any static electricity by touching the bare metal chassis of the unit case, or the bare
metal body
of any other grounded appliance.
Hold electronic circuit boards by the edges only. Never touch the components on the board unless it is
necessary to do so. Do not flex or stress the circuit board.
Leave all components inside the static-proof packaging that they shipped with until they are ready for
installation.
Use correct screws and do not over tighten screws.

The illustrations on the right
show a 2-pin jumper. When the
jumper cap is placed on both
pins, the jumper is SHORT. If
you remove the jumper cap, or
place
the jumper
cap on just
one pin, the jumper is OPEN.
Open (Off)
Short (On)
These illustrations show a 3-pin
jumper. Pins 1 and 2 are SHORT.
2.3
A jumper is the simplest kind of electric switch. It consists of two metal pins and a cap. When setting the jumpers,
ensure that the jumper caps are placed on the correct pins. When the jumper cap is placed on both pins, the
jumper is SHORT. If you remove the jumper cap, or place the jumper cap on just one pin,
Please see the following illustrations
the jumper is OPEN.
