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 the anti-static packaging from boards or integrated circuits until
you are ready to install them.
◼Before holding the board or integrated circuit, touch an unpainted portion of the
system unit 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.
