Fig. 3.23. Oxygen partial 
pressure and OLF displays. 
There is an audible alarm and 
the last segment of the bar graph 
starts to blink as oxygen partial 
pressure is greater than 1.4 bar 
or set value, and/or the OLF has 
reached 80% limit. When OLF 
has reached 100%, all segments 
starts to blink. If the OTU value 
is higher than the CNS value, the 
lowest segment blinks.

If set to EAN mode the NITROX display, with all 
labeled oxygen information, is shown immediately after 
activation. The nitrox display shows (Fig. 3.21.):

• 

oxygen percentage, labeled with O

2

%, is 

shown in the left side of the lower display

• 

set oxygen partial pressure limit, labeled 
with PO

2

, is shown in the right side of the 

lower display

• 

maximum allowed depth based on the set 
oxygen percentage and partial pressure limit

• 

current oxygen toxicity exposure shown 
with an Oxygen Limit Fraction (OLF) bar 
graph along the right side of the display.

In the Dive mode the current oxygen toxicity exposure 
is always shown with an Oxygen Limit Fraction 
(OLF) bar graph and the oxygen percentage labeled 
with O

2

%. The current oxygen partial pressure labeled 

with PO

2

is also shown, if selected (Fig. 3.22.). During 

a dive, the oxygen partial pressure, labeled with PO

2

,

is always shown instead of the preselected display, if 
the partial pressure is greater than 1.4 bar or the set 
value (Fig. 3.23.).
