The device used for treatment was returned for evaluation.The reported problem was not visually confirmed, however, the issue was confirmed when reviewing the case screenshots and log files.A review of the returned log files found multiple ¿over current¿ errors associated with ¿errordb-cutfemur¿ and ¿errordb-homehandpiece.¿ these ¿over current¿ errors in the log files were presented as ¿handpiece exposure motor control failure¿ and ¿handpiece error¿ (for homing) messages on the navio system.This is indicative of a connection/wiring issue within the handpiece.During the functional evaluation of the handpiece, a case was attempted and the handpiece incurred a homing error.This also confirms there is a connection/wiring issue within the handpiece.A review of manufacturing and service records indicate the device met all specifications upon release into distribution.A complaint history review for similar reported/confirmed complaints associated with the navio handpiece and failure mode(s) "error message(s)" identified similar events.The most likely cause of this event is an electrical failure of the handpiece cable.No containment or corrective actions are recommended at this time.
