Fig. 89 - HIGH O2
MAIN
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 Remaining 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.
