CAUTION:
Static electricity collects on non-conductors such as
paper, cloth, or plastic. A static discharge can be damaging even
though you often cannot see or feel it. To prevent damage to
circuit boards and/or components:
• Before touching any circuit board or component, touch the
metal frame of your computer to discharge any static
electricity.
•
Keep circuit boards and components away from non-
conductors.
