Safety Information

The components included in this package are prone to damage from electrostatic

discharge (ESD). Please adhere to the following instructions to ensure successful

computer assembly.

Ensure that all components are securely connected. Loose connections may cause

the computer to not recognize a component or fail to start.

Hold the motherboard by the edges to avoid touching sensitive components.

It is recommended to wear an electrostatic discharge (ESD) wrist strap when

handling the motherboard to prevent electrostatic damage. If an ESD wrist strap

is not available, discharge yourself of static electricity by touching another metal

object before handling the motherboard.

Store the motherboard in an electrostatic shielding container or on an anti-static

pad whenever the motherboard is not installed.

Before turning on the computer, ensure that there are no loose screws or metal

components on the motherboard or anywhere within the computer case.

Do not boot the computer before installation is completed. This could cause

permanent damage to the components as well as injury to the user.

If you need help during any installation step, please consult a certified computer

technician.

Always turn off the power supply and unplug the power cord from the power outlet

before installing or removing any computer component.

Keep this user guide for future reference.

Keep this motherboard away from humidity.

Make sure that your electrical outlet provides the same voltage as is indicated on

the PSU, before connecting the PSU to the electrical outlet.

Place the power cord such a way that people can not step on it. Do not place

anything over the power cord.

All cautions and warnings on the motherboard should be noted.

If any of the following situations arises, get the motherboard checked by service

personnel:

• Liquid has penetrated into the computer.

• The motherboard has been exposed to moisture.

• The motherboard does not work well or you can not get it work according to user

guide.

• The motherboard has been dropped and damaged.

• The motherboard has obvious sign of breakage.

Do not leave this motherboard in an environment above 60°C (140°F), it may damage

the motherboard.

Case stand-off notification

To prevent damage to the motherboard, any unnecessary mounting stand-off between

the motherboard circuits and the computer case is prohibited. The Case standoff keep

out zone signs will be marked on the backside of motherboard (as shown below) to

serve as a warning to user.

Avoid collision notification

Protective paint is printed around each screw hole to prevent parts from being

scratched.
