WARNING! PCI cards, like all computer equipment, can be severely damaged by static
electricity. Be sure that you are properly grounded before opening your computer
case or touching your PCI card. StarTech.com recommends that you wear an anti-static
strap when installing any computer component. If an anti-static strap is unavailable,
discharge yourself of any static electricity build-up by touching a large grounded
metal surface (such as the computer case) for several seconds. Also be careful to
handle the PCI card by its edges and not the gold connectors.
