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.
4. We will not be liable for any indirect, special, incidental or consequencial 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 con nectors by their ends.
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.

Safety Measures

To avoid damage to the system:
• Use the correct AC input voltage range.
To reduce the risk of electric shock:
ing. 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.

Safety Precautions

About the Package

• Use the correct DC input voltage range.
• 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.
• Keep this system away from humidity.
• Place the system on a stable surface. Dropping it or letting it fall may cause damage.
• The openings on the system are for air ventilation to protect the system from overheating. DO NOT COVER THE OPENINGS.
• Place the power cord in such a way that it will not be stepped on. Do not place anything on top of the power cord. Use a power cord that has been approved for use with the system and that it matches the voltage and current marked on the system’s electrical range label.
• If the system will not be used for a long time, disconnect it from the power source to avoid damage by transient overvoltage.
• If one of the following occurs, consult a service personnel:
- The power cord or plug is damaged.
- Liquid has penetrated the system.
- The system has been exposed to moisture.
The package contains the following items. If any of these items are missing or damaged, please contact your dealer or sales representative for assistance.
• DT122-GH system unit
• HDD drive bay kit
• Screw pack for M.2 installation
Optional Items
• Power Cord
The board and accessories in the package may not come similar to the information listed above. This may differ in accordance to the sales region or models in which it was sold. For more information about the standard package in your region, please contact your dealer or sales representative.

Before Using the System

Before powering-on the system, prepare the basic system components.
If you are installing the system board in a new system, you will need at least the following internal components.
• Memory module
• Storage devices such as hard disk drive, CD-ROM, etc.
You will also need external system peripherals you intend to use which will normally include at least a keyboard, a mouse and a video display monitor.
- The system is not working properly.
- The system dropped or is damaged.
- The system has obvious signs of breakage.
• The unit uses a three-wire ground cable which is equipped with a third pin to ground the unit and prevent electric shock. Do not defeat the purpose of this pin. If your outlet does not support this kind of plug, contact your electrician to replace the outlet.
• Disconnect the system from the DC outlet before cleaning. Use a damp cloth. Do not use liquid or spray detergents for cleaning.
