Safety Instructions
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 from your body.
 Wear a wrist-grounding strap, available from most electronic component
stores, when handling boards and components. Fasten the ALLIGATOR clip
of the strap to the end of the shielded wire lead from a grounded object.
Please wear and connect the strap before handle the product to ensure
harmlessly discharge any static electricity through the strap.
 Please use a conductive from pad when putting down any components or
parts or tools outside the computer. You may also use an anti-static bag
instead of the pad. If such a situation is not available, you can provide some
ESD protection by wearing an antistatic wrist strap and attaching if to a metal
part of the computer chassis. Please inquire from your local supplier for
additional assistance in finding the necessary anti-static gadgets.
NOTE: DO NOT TOUCH THE BOARD OR ANY OTHER SENSITIVE
COMPONENTS WITHOUT ALL NECESSARY ANTI-STATIC
PROTECTIONS.
