The default setting for maximum oxygen partial pressure is 1.4 bar, however you are
able to set it between the range of 1.2 - 1.6 bar.
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, and before the Dive Planning Mode. The
Nitrox display shows (Fig. 3.20.):
• the oxygen percentage, labeled with O
2
%, is shown in the left side of the center
window
• the set oxygen partial pressure limit, labeled with PO
2
, 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 Dive mode, the oxygen percentage labeled with O
2
% and the current oxygen toxicity
exposure shown with an Oxygen Limit Fraction (OLF) bar graph are shown (Fig. 3.21.
and Fig. 3.22.). During a dive, the oxygen partial pressure, labeled with PO
2
, is also
shown instead of the maximum depth in the upper right display, if the partial pressure
is greater than 1.4 bar or the set value (Fig. 3.23.).
By pressing the TIME button during a nitrox dive, the alternative display appears,
which includes (Fig. 3.24.):
