The reported complaint of "the autopulse platform (sn (b)(4)) displayed user advisory (ua) 07 (discrepancy between load 1 and load 2 too large) error message upon powering on" was confirmed during the functional testing and based on the archive data review.The root cause for the reported complaint was due to defective load cells, likely due to a defective component as a result of wear and tear or mishandling such as drop.The autopulse platform was manufactured in 2012 and is more than 7 years old, past the expected service life of 5 years.Upon visual inspection, a bent battery lock was observed, unrelated to the reported complaint.The probable root cause for the observed physical damage could be due to mishandling.The battery lock was replaced to address the observed physical damage.The autopulse platform failed initial functional testing due to ua07 error message upon powering on.The archive data review showed occurrence of multiple ua07 error message on the reported event date.Both the over reporting load cells were replaced to address the ua07 error.The autopulse platform subsequently passed the run-in test using the 95% patient large resuscitation test fixture (lrtf) with good known test batteries for 15 minutes without any fault or error.Following service, load cell characterization test was performed and confirmed both cell modules are functioning within the specification.The autopulse platform passed the final testing without any fault or error.Historical complaints were reviewed for service information related to the reported complaint and there was no previous history of complaint reported for autopulse platform with sn (b)(4).
