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.

System Memory
The system board is equipped with 2 LPDDR4X memory chips onboard.
Important:
Electrostatic discharge (ESD) can damage your board, processor, disk drives, add-in
boards, and other components. Perform installation procedures at an ESD workstation
only. If such a station is not available, you can provide some ESD protection by wear-
ing 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.
