The reported complaint of the eval autopulse platform (sn (b)(6)) does not turn on was not confirmed during functional testing.The reported complaint was not reproduced.The autopulse platform functioned as intended.Upon visual inspection, unrelated to the reported complaint, the backlight of the display flickers briefly when switched on and is dark afterwards.The root cause was a processor board failure, likely attributed to the device's aging.The autopulse platform was manufactured in 2013 and is 10 years old, past the expected service life of 5 years.The processor board was replaced to address the issue.Also unrelated to the reported complaint, the power distribution board (pdb) was out of date.The pdb was replaced to remedy the issue.The archive data review showed user advisory (ua) 16 (timeout moving to take-up position) error message, unrelated to the reported complaint.The autopulse platform passed the initial functional testing without any fault or error.The autopulse platform was tested with four autopulse li-ion batteries without any fault or error.The customer reported complaint and (ua) 16 observed in the archive could not be reproduced.User advisory is normally a clearable error message and is designed into the autopulse platform to alert the operator that autopulse has detected one of several conditions.Per the battery hangtag - advisory codes description and action, user advisory 16 is an indication that there is obstruction between the lifeband and patient, or a twisted lifeband.The recommended actions to take for this type of user advisory are: open lifeband, clear obstruction or twist, pull up completely on the lifeband, ensure that the patient and the band are properly aligned, and press restart.
