HIGH OXYGEN ACCUMULATION
The O2BG displays either O2 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 O2BG offers you a convenient way to consistently monitor
how close you are coming to the limits of O2 exposure. Use it
as a visual reference to place a wider margin of protection
between you and the Limits.
• Warning >> at 80% (240 OTU)
• Alarm >> at 100% (300 OTU)
When O2 accumulation increases to 80%, the Up Arrow icon
will appear and the graphic O2 will replace DTR (Fig. 49A)
If O2 reaches 100%, the full O2BG, graphic O2, and Up Arrow
icon will flash (Fig. 49B) until on the surface.
• Press/release the button momentarily (< 2 seconds) to view
the Alternate Displays (which are similar to those for No
Deco Stops).
