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 O2 appears and the full O2

Bar Graph and UP Arrow will be displayed flashing (Fig. 105).

The red LED warning will flash, the Audible Alarm will sound,

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 the A button to view the Alternate and Secondary

Displays.

  The unit will revert to the MAIN Display after 3 seconds.

Upon surfacing, operation will lock in to NORM Mode until the

O2BG recedes to4 segments.  Access to Watch Mode is al-

lowed but access to GAUG and FREE is blocked.
