Planning mode the Nitrox display shows
(Fig. 3.21.):
• 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 the Dive modes, the oxygen percentage
labeled with O
2
% and the current oxygen
toxicity exposure shown with an Oxygen Lim-
it Fraction (OLF) bar graph are shown
(Fig. 3.22. and Fig. 3.23.). If the wireless
transmission is enabled the O
2
% is shown
until the remaining air time is less than 30 mi-
nutes. After this, the remaining air time is dis-
played in its place. 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. 3.24.).
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 decom-
pression stop dive).
• remaining air time when remaining
air time is over 30min
• oxygen percentage when remaining
air time less than 30 min
