3.4.8 Partial pressure of oxygen
(ppO
operating depth (MOD)
The maximum partial pressure of oxygen
(ppO max), with a default of 1.4bar,
2
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 max, and consequently the MOD,
2
can be reduced manually when setting the
gas. See chapter: Settings, section: Gas
menu.
The MOD is a function of ppO
mixture used. If during the dive the MOD is
reached or exceeded, the Aladin Sport 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.
The MOD should not be exceeded. Disregarding
the warning can lead to oxygen poisoning.

3.4.9 Oxygen toxicity (CNS O
The Aladin Sport 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
The symbol "CNS O " is displayed together

with the percentage.
WARNING
An audible attention signal starts if oxygen
toxicity reaches 75%. The symbol "CNS O

Ascend to a shallower depth to decrease oxygen
