Alleged failure: continuous current without operating the footstep / probe with sparking at the electrode.The failure alleged in the complaint record was not confirmed/duplicated during the product investigation.The probable root cause/s could be an electrical short internal to the ceramic (location unable to be observed during a visual inspection, requires milling of ceramic to verify) or an error with the associated console used during surgery.The probe button stuck.A footswitch also can be used to activate the rf probe, therefore, the use of the footswitch can also be considered a possible root cause.The product was returned for investigation and the failure mode will be monitored for future reoccurrence.
