In Case of Failure 
  Check any broken of the enclosure. Replace any defective part. 
  Inspect wiring for bad crimps, poor connections, or damage. 
  Test the wall outlet; verify it is grounded and is free of other wiring abnormalities. 
Notify the user or owner to correct any deviations. As a work around, check the other 
outlets to see if they could be used instead. 
  Change another probe to confirm if the fail is caused by console. 
  If the leakage current measurement tests fail on a new unit and if situation can not be 
corrected, submit a Safety Failure Report to document the system problem. Remove unit 
from operation. 
  If all else fails, stop using and inform the Customer Service Engineer for analysis and 
disposal.
