Important:
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.
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.
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 sta-
tion 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 protec-
tion.

About the Package
The package contains the following items. If any of these items are missing or damaged,
please contact your dealer or sales representative for assistance.
• 1 DT122-CR system unit
• 1 HDD drive bay kit
• 1 CD disk includes
- Manual
- Drivers
• 1 Quick Installation Guide
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.
Safety Precautions
• Use the correct DC input voltage range.
• 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.
• 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 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.
