Qn#(b)(4).The sample was returned for evaluation.A visual exam was performed and there were no major defects observed.Functional testing was performed and the unit was connected to 120vac; however, the unit did not pass the power-on self-test (p.O.S.T.).The power button was not illuminating and when pressed , the unit did not power on.The unit was opened and it was noted that the power harness had heat damage at its connector.The power supply board was replaced with a known good lab inventory board.This time, the unit was able to pass the power-on self-test with no issues.During the temperature display accuracy test the unit displayed the correct temperatures and properly alarmed in the high temperature scenario.The complaint has been confirmed.The investigation revealed a defective power supply board.Since the neptunes are 100% functionally tested during manufacturing assembly, it is unlikely that the failure was present at the time of release.A device history record review was performed with no evidence to suggest a manufacturing related issue.The unit was manufactured in 2015 and was designed for a minimum of 5 years.The root cause for the failure is normal wear.Teleflex will continue to monitor and trend on complaints of this nature.
