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 O2 Bar Graph allows you to monitor
how close you are coming to the limits of oxygen exposure.
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 (300 OTU), Oxygen Dive Time Remain-
ing becomes 0:00 (hr:min), the graphic O2BG appears and
the full O2 Bar Graph and UP Arrow will be displayed flashing
(Fig. 89).
The Audible Alarm will sound, the red LED will flash, and the
message HIGH > O2 will scroll at the top of the display.
When the Alarm is acknowledged/silenced, the message UP >
HIGH > O2 will scroll until the level of oxygen decreases
below the limit.
Press/release the A button to view the Alternate, then
Secondary Displays.
They will revert to the MAIN Display after 5 seconds.
Upon surfacing, operation will lock in to NORM Mode until the
O2BG recedes to 4 segments. Access to Watch Mode is
allowed but access to GAUG and FREE is blocked.
