Attention:
v Attach a wrist strap to an unpainted metal surface of your hardware to prevent electrostatic
discharge (ESD) from damaging your hardware.

does not increase or decrease your risk of receiving electric shock when using or working on
electrical equipment.
v If you do not have a wrist strap, just prior to removing the product from ESD packaging and
installing or replacing hardware, touch an unpainted metal surface of the system for a minimum of
5 seconds.
