Specifications

The O2 Bar Graph provides you with a convenient graphic representation of

your oxygen accumulation, displaying either oxygen accumulated during that

dive, or during the repetitive dives you conduct during that 24 hour period,

whichever of the two is greater at that time.

The yellow Caution Zone of the O2 Bar Graph offers you a convenient way to

consistently monitor how close you are coming to the limits of oxygen toler-

ance. Use it as a visual reference to place a wider margin of protec-

tion between you and the Limits.

If the theoretical amount of oxygen accumulated equals, or exceeds, the limit

for a single exposure, or the exposure limit for a 24 hour period, Oxygen Dive

Time Remaining becomes zero (0:00) and the O2 Bar Graph will enter the red

danger zone (Fig. 77). The full O2 Bar Graph will flash and the Audible Alarm

will emit one beep per second* as a warning until the level of oxygen decreases

below the limit.

*If the Audible Alarm feature was set to OFF, only a double beep.

You must immediately focus on making a safe controlled ascent to the sur-

face to prevent further exposure. As your accumulation (dose) decreases dur-

ing your surface interval, the O2 bar graph will gradually recede into the yel-

low (caution) zone and green (normal) zone.
