The customer complaint of platform did not start compressions was confirmed during review of the retrieved archive data and functional testing of the returned autopulse platform (sn (b)(4)).Following service, including replacement of the front enclosure, the platform passed all testing criteria.As part of routine service during testing, the platform was examined and found damaged front enclosure, unrelated to the reported complaint.Front enclosure was replaced to address the issue.Review of the retrieved archive data, found a system error message (a single event of latch error 71-motor drive train command issue) occurred on the reported event date.In addition, the archive data also showed ua2 (compression tracking error) and ua28 (loss of clutch connectivity) occurred on the reported event date, unrelated to the reported complaint.To remedy the system error (latch error 71), ap vision 3 software was used to clear this error.User advisory 2 is an indication that the autopulse has detected a change in lifeband tension.This advisory can happen when the patient or lifeband is out of position, or if the lifeband is opened during active operation.Initial functional testing could not be completed since the reported system error message (latch error 71) appeared upon powering on the platform.Historical complaints were reviewed for service information related to the reported complaint and there was no similar complaint reported for autopulse with serial number (b)(4).
