CAUTION
ESD Hazard! ESD (Electrostatic Discharge) can cause software crashes,
data and/or communications problems. Failure to use proper ESD pro-
cedures will cause damage to electronic components (example: PCBs).
ESD problems can be minimized by maintaining all machine ground con-
nections, ensuring the proper handling of circuit boards and sensors. Use
ESD protection when working near PCBs. Failure to use ESD protection is
likely to result in a PCB failure ( Service Manual BM 200 3.1 ).
