Removing The Time-Of-Day Battery - IBM 9080-M9S Manual

Attention:
• Attach an electrostatic discharge (ESD) wrist strap to the front ESD jack, to the rear ESD jack,
or to an unpainted metal surface of your hardware to prevent the electrostatic discharge from
damaging your hardware.
• When you use an ESD wrist strap, follow all electrical safety procedures. An ESD wrist strap is
used for static control. It does not increase or decrease your risk of receiving electric shock
when using or working on electrical equipment.
• If you do not have an ESD 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. If at any point in this service process you move away from the
system, it is important to again discharge yourself by touching an unpainted metal surface for
at least 5 seconds before you continue with the service process.
