To avoiddamage, keep static-sensitive devices in their static-protective package until you areready to install them.To reduce the possibility of electrostatic discharge, observe the following precautions:• Limit your movement. Movement can cause static electricity to build up aroundyou.• Handle the device carefully, holding it by its edges or its frame.• Do not touch solder joints, pins, or exposed printed circuitry.• Do not leave the device where others can handle and possibly damage thedevice.• While the device is still in its static-protective package, touch it to an unpaintedmetal part of the system unit for at least two seconds. (This drains static electricityfrom the package and from your body.)• Remove the device from its package and install it directly into your system unitwithout setting it down. If it is necessary to set the device down, place it in itsstatic-protective package. Do not place the device on your system unit cover or ona metal table.• Take additional care when handling devices during cold weather because heatingreduces indoor humidity and increases static electricity.
