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 supporting 1600MHz delivers increased system bandwidth and im-
proved 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. It supports VGA, LVDS and DDI
interfaces for 3 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. The bandwidth of the SATA 3.0 will be limited by
carrier board design.
• Gigabit LAN
The Intel®I218LM with iAMT9.5 Gigabit LAN controller supports up to 1Gbps data transmis-
sion.
• 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.
