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.

Notice:

1. The changes or modifications not expressly approved by the party responsible for compli-

ance 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.

Warranty

1. Warranty does not cover damages or failures that arised 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 subjected to physical abuse, improper instal-

lation, modification, accidents or unauthorized repair of the product.

3. Unless otherwise instructed in this user’s manual, the user may not, under any circum-

stances, 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 consequencial damages to the

product that has been modified or altered.

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.

Important:

Electrostatic discharge (ESD) can damage your processor, disk drive and other com-

ponents. Perform the upgrade instruction procedures described at an ESD worksta-

tion 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 chas-

sis. If a wrist strap is unavailable, establish and maintain contact with the system

chassis throughout any procedures requiring ESD protection.

Features

• Watchdog Timer

The Watchdog Timer function allows your application to regularly “clear” the system at the set

time interval. If the system hangs or fails to function, it will reset at the set time interval so

that your system will continue to operate.

• DDR3L

DDR3L is a higher performance DDR3 SDRAM interface providing less voltage and higher

speed successor. DDR3L SDRAM modules support 1600MHz for DDR modules. DDR3L delivers

increased system bandwidth and improved performance to provide its higher bandwidth and its

increase in performance at a lower power.

• Graphics

The integrated Intel®HD graphics engine delivers an excellent blend of graphics performance

and features to meet business needs. It provides excellent video and 3D graphics with out-

standing graphics responsiveness. These enhancements deliver the performance and compat-

ibility needed for today’s and tomorrow’s business applications. Supports 1 x DDI (HDMI/DVI/

DP++) and 1 x LVDS/eDP interfaces for display outputs.

• Serial ATA

Serial ATA is a storage interface that is compliant with SATA 1.0a specification. With speed of

up to 6Gb/s (SATA 3.0), it improves hard drive performance faster than the standard parallel

ATA whose data transfer rate is 100MB/s.

• Gigabit LAN

The Intel®I210AT Gigabit LAN controller or the Intel®I210IT Gigabit LAN controller supports

up to 1Gbps data transmission.

• USB

The system board supports the new USB 3.0. It is capable of running at a maximum transmis-

sion speed of up to 5 Gbit/s (625 MB/s) and is faster than USB 2.0 (480 Mbit/s, or 60 MB/s)

and USB 1.1 (12Mb/s). USB 3.0 reduces the time required for data transmission, reduces

power consumption, and is backward compatible with USB 2.0. It is a marked improvement in

device transfer speeds between your computer and a wide range of simultaneously accessible

external Plug and Play peripherals.
