  OSTC3 Warnings:
		niedriger Batteriezustand (
		zu hoher oder zu niedriger Sauerstoffpartialdruck (ppO2) 0.2 - 1.6
		zu hoher CNS (Gefahr der Sauerstoffvergiftung) 90%
		zu hohe Gradientenfaktoren 90 - 90
		Missachtung der Dekostopps (der ï¿½berschrittene Dekostopp wird rot angezeigt) 0 m
		zu hohe Aufstiegsgeschwindigkeit 30 m/min
		aGF-Warnung: die Berechnung der Dekompression wird ï¿½ber alternative GF-Werte durchgefï¿½hrt
		Fallback-Warnung bei ausgefallenem Sensor
