label NITROX, is shown after activation. In
Dive 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 la-
beled with O
2
% and the current oxygen toxicity
exposure shown with an Oxygen Limit Frac-
tion (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 remain-
ing air time is less than 30 mi nutes. After this,
the remaining air time is displayed in its place.
During a dive, the oxygen partial pressure, la-
beled 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 de com-
pression stop dive).
• remaining air time when remaining air
time is over 30min
• oxygen percentage when remaining
air time less than 30 min
