Installation Notice
The manufacturer recommends using a grounded plug to ensure proper
motherboard operation. Care should be used in proper conjunction with a
grounded power receptacle to avoid possible electrical shock. All integrated
circuits on this motherboard are sensitive to static electricity. To avoid damaging
components from electrostatic discharge, please do not remove the board from the
anti-static packing before discharging any static electricity to your body, by
wearing a wrist-grounding strap. The manufacturer is not responsible for any
damage to the motherboard due to improper operation.
