vAlways handle components carefully. Handle adapters and memory modules by the edges. Never touch any exposed circuitry.

vPrevent others from touching components.

vWhen you install a new option, touch the static-protective package containing the option to a metal expansion-slot cover or other unpainted metal surface on the computer for at least two seconds. This reduces static electricity in the package and your body.

vWhen possible, remove the option and install it directly in the computer without setting the option down. When this is not possible, place the static-protective package that the option came in on a smooth, level surface and place the option on it.

vDo not place the option on the computer cover or other metal surface.
