WARNING: CMOS Battery Damage
Replace your system’s CMOS RAM battery only with the identical CR-2032 3V Lithium-Ion coin
cell (or equivalent) battery type to avoid risk of personal injury or physical damage to your
equipment. Always dispose of used batteries according to the manufacturer’s instructions, or
as required by the local ordinance (where applicable). The damage due to not following this

Motherboard Layout:
WARNING: Electrostatic Sensitive Device (ESD)
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 cards 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!
