This complaint originated when a customer contacted ge healthcare after receiving the notification of fmi 30074 for uncontrolled motion (1651104-03/16/15- 002-c).The customer stated they saw similar symptoms on their own treadmill.A ge field engineer (fe) inspected the treadmill on site.The reported behavior could not be reproduced by the fe.Log files from the customer's treadmill and case system data from an exercise test were obtained.The customer indicated to the fe that the stress test data was from the test in which the incident occurred.The analysis of the log files and stress test data shows the following: at time 9:19:25 stress test started.At time 9:26:04 the treadmill belt was started 3 seconds before the start of bruce exercise protocol stage 1.At time 9:31:11 the treadmill belt was stopped 13 seconds into the recovery phase.The stress test data reports all treadmill speed and grade values according to the bruce protocol.No abnormalities can be seen in the log file or stress test data.Prior to this stress test there are 2 entries for emergency stop recorded at 8:48 and 8:50.These appear in the log as "emergency stop was initiated <00>", which is an e-stop command sent from the case, which are issued when the case stop treadmill button is pressed twice consecutively.When the e-stop button on the treadmill is pressed, the log will record the entry as "emergency stop was initiated <255>".This does not match the customer description of the reported incident.There are no errors or indication of any problems in the treadmill log associated with these e-stop entries.In the entire treadmill log there are 131 entries for e-stop commands issued from the case, thus the customer appears to regularly stop the treadmill in this way.The treadmill log file indicated no errors on (b)(6)-2015, the reported date of the incident, nor were any errors recorded in the previous 4 years.No additional information was obtained about this incident.Root cause is undetermined.Corrections: date of event is: (b)(6) 2015.The complaint is not related to fmi 30074.
