During the preventive maintenance (pm, the autopulse platform (sn (b)(4) could not be powered on as the power button was "pushed in" into the platform.The root cause was determined to be a broken power button mounting bracket, likely attributed to wear and tear.However, user mishandling cannot be ruled out.The autopulse platform was manufactured in january 2014 and is over 8 years old, and has exceeded its expected service life of 5 years.During visual inspection, it was observed that the on/off power switch mounting bracket was broken, and this caused the power button assembly to fall inside of the platform.The on/off power switch mounting bracket was replaced to address the observed issue.Following service, the autopulse was subjected to the run-in test using the 95% patient large resuscitation test fixture (lrtf) with good known test batteries until discharged without any fault or error.A 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 similar complaint reported for autopulse platform with a serial number (b)(4).
