The 8820 MSR circuit cards can be damaged by static electricity that builds up on
work surfaces and on your body. Static is produced by the everyday movement of
your body, and is released as an Electro-Static Discharge (ESD) when you touch an
object. Observe the following precautions whenever you are working with the 8820
MSR.
• Always wear a grounded wrist strap to prevent ESD damage to the 8820 MSR
system components.
• Be sure to attach the wrist strap to the grounding jack located on the front panel
of the equipment.
