CAUTION To prevent electrostatic discharge (ESD) damage, earth ground the work area
and yourself. Some of the assemblies being handled in the following
procedures are very sensitive to damage resulting from static discharges.
Assemblies exposed to ESD may or may not continue to operate properly.
Their reliability, however, will be degraded. Refer to Figure 6-1 for
ESD-safe workstation recommendations.
