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).

POST DIVE SURFACE MODE
When you ascend to 2 FT (0.6 M) for 1 second, the Element will
enter Surface Mode and begin counting Surface Interval.
TRANSITION PERIOD
The first 10 minutes is, in affect, a Transition Period during which
time the following information is displayed (Fig. 50):
• Surface Interval time (colon flashing) with mode icon
• Temperature (ambient) with icon and graphic C (or F)
• Time of Day with clock icon
• Number of that dive (during that activation period) with icon
• Battery icon, if a Low Battery condition exists
• NiBG, and O2BG (if a Nitrox dive)
During the Transition Period, the Log for that dive can be viewed.
No other modes (e.g., Fly, Desat, Plan, Set) are accessible.
To view the Log (Fig. 51), press/release the button (less than 2
seconds).
Log Data will not be stored in the unit's memory until the 10
minute Transition Period on the surface is completed.

If you descend during the 10 minute Transition Period, time
underwater will be considered a continuation of that dive. The
time at the surface (if less than 10 minutes) will not be added as
Elapsed Dive Time.
AFTER THE TRANSITION PERIOD (THE FIRST 2 HOURS)
Once 10 minutes have elapsed, the Surface Interval time display
colon stops flashing indicating that the Dive and Transition
Period are completed, and a subsequent descent will be consid-
ered a new dive.
For the remainder of the first 2 hours after surfacing, information
will continue to be displayed as the Surface Sequence, scrolling
through the Surface Mode >> Fly >> Sat >> Plan screens. You
will also have full access to Log and Set modes.
Time to Fly/Desaturate
The Time to Fly and Desat Timers begin counting down 10
minutes after surfacing from a dive (after the Transition Period).
The FLY countdown (Fig. 52) always begins at 23:50 (hr:min)
and the Desat countdown (Fig. 53) at 23:50 (maximum).
If a Violation occurred during the dive a single dash ( - ) will
appear instead of the letters FLY. DeSat time will not be dis-
played.
