ALADIN ONE USER MANUAL
3.4.7 Partial pressure of oxygen
(ppO
2
max)/Maximum
operating depth (MOD)
The maximum partial pressure of oxygen
(ppO
2
max), with a default of 1.4bar,
determines the Maximum Operating Depth
(MOD). Diving deeper than the MOD
exposes you to oxygen partial pressures
higher than the set maximum level.
The ppO
2
max, and consequently the MOD,
can be reduced manually when setting the
gas. See chapter:
Settings , section: Gas
menu.
WARNING
The MOD is a function of ppO
2
max and the
mixture used. If during the dive the MOD is
reached or exceeded, the Aladin One sends
an audible attention message and the MOD is
displayed (flashing) in the lower left corner. If
this occurs, ascend to a depth shallower than
the displayed MOD in order to diminish the
danger of oxygen poisoning.
WARNING
The MOD should not be exceeded. Disregarding
the warning can lead to oxygen poisoning.
3.4.8 Oxygen toxicity (CNS O
2
%)
The Aladin One calculates oxygen toxicity
based on depth, time and gas mixture,
and displays it in the lower right corner
when the value is greater than 50%. The
toxicity is expressed in 1% increments of a
maximum tolerated value (CNS O
2
clock).
The symbol “CNS O
2
” is displayed together
with the percentage.
WARNING
An audible attention signal starts if oxygen
toxicity reaches 75%. The symbol “CNS O
2
%”
flashes.
Ascend to a shallower depth to decrease oxygen
loading, and consider terminating the dive.
WARNING
When oxygen toxicity reaches 100%, an audible
alarm sounds every 4 seconds. “CNS O
2
” and
the percentage value flash, indicating the
danger of oxygen toxicity! Start procedure for
terminating the dive.
F
NOTE:
• During an ascent, and if the CNS O
2
%
value does not increase (due to a
lower partial pressure of oxygen), the
audible warning is suppressed.
