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.
