Afterfiveminutes,iftheoxygenpurityexceeds85%±2%,theGREENlightwillcontinue

andwaitforamaximumof30minutesfromstart‐uptoreach
85%±2%beforeactivatinganalarm.Environmentalfactorssuchaslowvoltage,high
altitude,orageofthemachinewillaffectthetimerequiredtoreach85%±2%.
Iftheoxygenlevelisnotabove85%±2%withinthefirst30minutes,theoxygen

Whenoxygenconcentrationisabove85%±2%,thesensormeasuresoxygenpurityevery
10minutes.Ifareadingfallsbelow85%±2%,aYELLOWlightwillilluminate.Ifthe
