The monitor was returned to the manufacturer, but not the charger cord component.Engineering evaluation was completed by on 28feb2023.Results are as follows: device was inspected for general physical integrity, charging port was partially melted.Device started charge at 7:00am at 1463.8ma.Device was charged fully at 8:58am at 352.8ma max temperature at 86.0f, normal.Total device charging time: 1 hour and 58 minutes device charged fully; no problems found.Heat stress blue tooth test was performed.Test started at 9:25am and completed test at 10:55am.Max temperature was 84.0f.No problems found.Device was opened inspect the printed circuit board near the charging port.No damage found.It is unlikely that the monitor was the source of the melt event.Conlusion: engineering evaluation was able to confirm a melt event.It is unlikely that the monitor contributed to the event.It is most probable that a fault event occurred with the charging cord.However, the charging cord was not returned and was discarded.
