1.3 Safety Precautions
Follow these simple precautions to protect yourself from harm and the
products from damage.
1. To avoid electric shock, always disconnect the power from your PC
chassis before you work on it. Don't touch any components on the
CPU card or other cards while the PC is on.
2. Disconnect power before making any configuration changes. The
sudden rush of power as you connect a jumper or install a card may
damage sensitive electronic components.
3. Always ground yourself to remove any static charge before you
touch your CPU card. Be particularly careful not to touch the chip
connectors. Modern integrated electronic devices, especially CPUs
and memory chips, are extremely sensitive to static electric dis-
charges and fields. Keep the card in its antistatic packaging when it
is not installed in the PC, and place it on a static dissipative mat
when you are working with it. Wear a grounding wrist strap for
continuous protection.
