WARNING: Electrostatic Sensitive Device (ESD)
Version 0.1 http://www.bcmcom.com
Static electricity can easily damage your motherboard and will void your motherboard warranty. Keep
the motherboard and other system components in their anti-static packaging until you are ready to
install them. Touch a grounded surface before you remove any system component from its protective
anti-static packaging. Unpacking and installation should be done on a grounded, anti-static mat. The
operator should be wearing an anti-static wristband, grounded at the same points as the anti-static
mat. During configuration and installation touch a grounded surface frequently to discharge any static
electrical charge that may have built up in your body. Avoid touching the components when handling
the motherboard or a peripheral card. Handle the motherboard and peripheral c ards either by the
edges or by the peripheral card case-mounting bracket.
WARNING: Misplaced Jumper Damage
Incorrect setting jumpers and connectors may lead to damage to your motherboard and will void your
motherboard warranty. Please pay special attention not to connect these headers in wrong
directions. DO NOT change ANY jumpers while the motherboard has the power!
