Siemens has completed an investigation of the reported event.The root cause was determined to be an operator error.The evaluation of the log files showed that the operator of the system very often used the sleep mode (hibernation mode) of the system, but without completely shutting down the system (rebooting), as required in the user manual.The previously mentioned hibernation mode is a special mode that allows the user to use the system again extremely quickly for urgent operations (e.G., emergency cases) without having to shut it down completely first.However, this mode cannot be used permanently, as it is also described accordingly in the user manual.The basic function is as follows: after the 10th hibernation mode via the off key, a dialog window opens, via which you can select the hibernation mode or the complete shutdown of the system.After the 15th hibernation mode via the off key, a complete shutdown is automatically performed with a corresponding notification to the user.This is a specified and described function.Although this can't be verified retrospectively, system experts agree that acting against the user manual, i.E., not shutting down the system completely, led to the working memory overfilling and ultimately caused the problem described in the complaint.This thesis is also supported by the fact that the error has not been reported since the customer agreed to the procedure described in the user manual and has since then completely switched off the system in the evening.The occurrence rate of the error pattern was checked.A possible error accumulation or even a systematic error that would lead to a corrective action of the installed base could not be determined by the investigation.After detailed investigation, the incident is not classified as a reportable event as neither serious injury, death nor an unexpected, prolonged hospitalization of the patient or any other person occurred or could be expected.
