HIGH OXYGEN ACCUMULATION
The O2 Bar Graph displays either oxygen accumulated
during that nitrox dive, or during the repetitive nitrox 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 exposure. Use it as a visual
reference to place a wider margin of protection
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 O2
(Danger) Zone (Fig. 68). The red LED warning will flash,
the Audible Alarm will sound (unless set OFF), and the UP
Arrow and the full O2 Bar Graph will flash as a warning until
the level of oxygen decreases below the limit.
Press the Left (Advance) button to view the Alternate
Displays.
The unit will revert to the Main Display after 3 seconds.
Press the Right (Select) button to activate the Backlight.
