3.4.2. OXYGEN DISPLAYS
If set to Nitrox mode the NITROX display, with all
labeled oxygen information and the label NITROX, is
shown after activation. In Dive Planning mode the nitrox
display shows (Fig. 3.21.):
•
the oxygen percentage, labeled with O
shown in the left side of the center window
•
the set oxygen partial pressure limit, labeled
with PO
, is shown in the upper right

display
•
the maximum allowed depth based on the set
oxygen percentage and partial pressure limit
•
the current oxygen toxicity exposure shown
with an Oxygen Limit Fraction (OLF) bar
graph along the left side of the display
(instead of the CBT).
In the Dive modes, the oxygen percentage labeled
with O
% and the current oxygen toxicity exposure

shown with an Oxygen Limit Fraction (OLF) bar graph
are shown (Fig. 3.22. and Fig. 3.23.). The O
until the remaining air time is less than 30 minutes.
After this, the remaining air time is displayed in its
place. During a dive, the oxygen partial pressure,
labeled with PO
maximum depth in the upper right display, if the partial
pressure is greater than 1.4 bar or the set value (Fig.
3.24.).
By pressing the TIME button during a nitrox dive,
the alternative display appears, which includes (Fig.
3.25.):
•
current time
•
temperature
•
Consumed Bottom Time
•
maximum depth (during decompression stop
dive).
•
Oxygen percentage when remaining air time
less than 30 min
After five seconds the display will automatically revert
to the original display.
