Safety Notes
Components that can be Destroyed by Electrostatic Discharge (ESD)
CAUTION
The board contains components that can be destroyed by electrostatic discharge.
These components can be easily destroyed if not handled properly. If you do have
to use electronic boards, however, please observe the following:
• You should only touch electronic boards if absolutely necessary.
• If you have to touch boards, however, your body must be electrically discharged
beforehand.
• Boards must not come into contact with highly insulating materials (such as
plastic parts, insulated desktops, articles of clothing manufactured from man-
made fibers).
• Boards must only be placed on conductive surfaces.
• Boards and components should only be stored and transported in conductive
packaging (such as metalized plastic boxes or metal containers).
• If the packaging material is not conductive, the boards must be wrapped with a
conductive packaging material (such as conductive foam rubber or household
aluminum foil).
The necessary ESD protective measures are clearly illustrated in the following
