The device logbook was analyzed for the day of the reported event, 23.11.2023.No conspicuous entries were found in connection with the reported device failure.It can only be verified that the device was switched on at 7:31 in the morning and again at 9:28.A test run of the device also showed no anomalies.A check of the on/off switch also revealed no results - no deviation from the specification could be identified.As part of the investigation, further case-specific questions were asked, which unfortunately remained unanswered.As no evidence of a device malfunction could be found, it can be assumed that an unintentional activation of the on/off switch caused the device to switch off.The two switch-on processes, as can be seen in the log, confirm this assumption.The first switch-on occurred at the beginning of the procedure in question.Since a switch-off of the device is not recorded in the log, the next entry (after an accidental switch-off) that can be traced in the log is the switch-on sequence.Finally, no device error could be found as cause for the reported symptoms.An user-related cause seems very likely in this case.The analysis of the complaint data does not indicate a systematic accumulation of the symptom described.On the basis of the available investigation results, the case is subsequently assessed as not reportable.
