(b)(4).The head harness connectors of an iw932jeu baby control cosycot infant warmer, which were reported to be discoloured, were not returned to fisher & paykel healthcare (fph) for investigation.An attempt was made to obtain photos of the discoloured head harness connectors but no response was received from the hospital.Our analysis is accordingly based on our previous investigations on similar complaints, and our knowledge of the product.The upper and lower head harnesses are used to connect the head unit to the control unit of the infant warmer.Previous investigations on similar complaints revealed that the discoloration was most likely due to poor electrical contact caused by the degradation of the harness connectors.This degradation is likely a result of swivelling of the warmer head.It should be noted that the subject infant warmer unit was nine years old at the time of the reported malfunction.All components on the harness assembly of the infant warmer are enclosed in a sheath and fire rated by underwriters laboratories (ul).The entire harness is enclosed in a ul v-0 rated fire retardant enclosure.Should the connectors completely fail, the infant warmer displays an error code and enters a fail safe state where the heater element is disabled and the infant warmer alarms to allow the user to act and provide an alternate means of warming.The infant warmer technical/service manual also contains a checklist which specifies that users perform safety, performance, and functional checks at least once a year.
