ESD Precautions
Integrated circuits on computer boards are sensitive to static
electricity. To avoid damaging chips from electrostatic
discharge, observe the following precautions:
!Do not remove boards or integrated circuits from their anti-
static packaging until you are ready to install them.
!Before handling a board or integrated circuit, touch an
unpainted portion of the system unit chassis for a few
seconds. This helps to discharge any static electricity on
your body.
!Wear a wrist-grounding strap, available from most electronic
component stores, when handling boards and components.
