Caution
The interface board contains electronic comp onents that can be
damaged by static electricity through electrostatic discharge(ESD).
To prevent ESD damage,maintain frequent contact with any bare
sheet metal surface on the chassis. A grounding wrist strap (or
similar device) is useful for this purpose. Handle the b oard carefully
at all times. Avoid touching electronic comp onents or circuit paths.
