CAUTION
ESD Hazard! ESD (Electrostatic Discharge) can cause software crashes, data and/or
communications problems. Failure to use proper ESD procedures will cause dam-
age to electronic components (example: PCBs). ESD problems can be minimized by
maintaining all machine ground connections, ensuring the proper handling of circuit
boards/ sensors, refer to the general caution description at the beginning of section 3.
- Use ESD protection when working near PCBs. Failure to use ESD protection is likely
to result in a PCB failure.
