The autopulse platform in complaint was returned to zoll on (b)(4) 2014 for investigation.Investigation results as follows: visual inspection of the returned platform shows that the top cover and the front enclosure were cracked and the battery lock was bent.The physical damages found during visual inspection are not related to the reported event of the platform showing a user advisory (ua) 45 (not at "home" position after power-on/restart) message.The damages appear to have been caused by normal wear and tear (autopulse manufactured in february of 2008).A review of the archive was performed and the reported complaint of the platform showing a ua 45 message was confirmed.The archive data shows that multiple ua 45 messages occurred on the reported event date of (b)(6) 2014.Functional testing was performed and the reported issue of a ua 45 message was confirmed.Upon power up of the platform, the ua 45 message was observed.It was found that the driveshaft was not at the "home" position, which caused the lifeband to not work as intended.The driveshaft was rotated back to the "home" position and the platform ran for 7 minutes with no problems observed.Based on the initial investigation, the parts identified for replacement were the top cover, front enclosure and the battery lock.In summary, the reported complaint of a ua 45 message was confirmed based on the archive review and upon functional testing.Additionally, the customer's reported complaint that the lifeband was not working was also confirmed during functional testing.The faults were found to be due to the driveshaft not being at the "home" position.The physical damages found during visual inspection are unrelated to the reported complaint.
