ESD Precautions

Computer boards have integrated circuits sensitive to static electricity. To prevent chipsets

from electrostatic discharge damage, please take care of the following jobs with precautions:

Do not remove boards or integrated circuits from their anti-static packaging until you are

ready to install them.

Before holding the board or integrated circuit, touch an unpainted portion of the system

unit chassis for a few seconds. It discharges static electricity from your body.

Wear a wrist-grounding strap, available from most electronic component stores, when

handling boards and components.
