Safety and precautions
Computer components and electronic circuit boards can be damaged by discharges of static electricity.
Working on computers that are still connected to a power supply can be extremely dangerous. Follow these
guidelines to avoid damage to the computer or injury to yourself.
• Always disconnect the unit from the power outlet.
• Leave all components inside the static-proof packaging that they ship with until they are ready for
installation.
• After replacing optional devices, make sure all screws, springs, or other small parts are in place and
are not left loose inside the case. Metallic parts or metal akes can cause electrical shorts.
If the LCD breaks and uid gets onto your hands or into your eyes,
immediately wash with water and seek medical attention.
