Preventing ESD
Before servicing this product, read the General Safety Summary and the Service
Safety Summary at the front of the manual, as well as the following ESD
information.
CAUTION. Electrostatic discharge (ESD) can damage any semiconductor
component in this instrument.
When performing any service that requires internal access to the instrument,
adhere to the following precautions to avoid damaging internal modules and their
components due to electrostatic discharge:
1. Minimize handling of static-sensitive circuit boards and components.
2. Transport and store static-sensitive modules in their static protected
containers or on a metal rail. Label any package that contains static-sensitive
boards.
3. Discharge the static voltage from your body by wearing a grounded antistatic
wrist strap while handling these modules.
4. Service static-sensitive modules only at a static-free work station.
5. Do not allow any items capable of generating or holding a static charge on
the work station surface.
6. Handle circuit boards by the edges when possible.
7. Do not slide the circuit boards over any surface.
8. Avoid handling circuit boards in areas that have a floor or work-surface
covering capable of generating a static charge.
