ALADIN SPORT USER MANUAL
Desaturation time is determined either by
oxygen toxicity, nitrogen saturation or the
regression of microbubbles, depending on
which requires the longer time.
No-dive warning
If the Aladin Sport detects a situation of
increased risk (due to the potential of
microbubble accumulation from previous
dives or a CNS O
2
level above 40%), the
“no-dive” symbol will appear on the display.
The duration of the no-dive warning is
visible in the dive planner menu. The Aladin
Sport recommends this as a minimum
surface interval in order to reduce the
number of microbubbles and/or to reduce
the CNS O
2
level below 40%.
F
NOTE: You should not undertake a
dive as long as the no-dive warning
message is displayed on the computer
screen. If the warning is prompted
by microbubble accumulation (as
opposed to CNS O
2
over 40%) and you
dive anyway, you will have shorter no-
stop times or longer decompression
times. Moreover, the duration of the
no-dive warning at the end of the dive
can increase considerably.
3.6 Diving in mountain lakes
3.6.1
Altimeter
The altitude adjustment (see chapter:
SETTINGS, section: Altitude adjustment
)
does not affect altitude classes nor any
calculations.
3.6.2
Altitude classes
The Aladin Sport measures the
atmospheric pressure every 60 seconds,
even while the display is switched off. If
the computer detects a sufficient increase
in altitude, it switches on automatically
and indicates the new altitude class (1-4)
and the desaturation time. Desaturation
time indicated at this moment refers to the
adaptation time at this altitude. If the dive
starts within this adaptation time, the Aladin
Sport treats it as a repetitive dive, since the
body is off-gassing.
Altitude is divided into 5 classes, which
are influenced by barometric pressure.
That is why the defined altitude classes
overlap on their fringes. If a mountain lake
is reached, the altitude class is indicated
at the surface (time of day display), in the
logbook and in the dive planner with a
stylized mountain icon and the current
altitude class. The altitude from sea level
to approximately 1000m/3280ft is not
indicated. In the following diagram, you
can see the approximate breakdown of the
altitude classes:
