minutes. The delay allows for surfacing for
a short period for orientation.
After 5 minutes, the dive is closed and is
entered into the logbook. The desaturation
time, the no-fly time, the no-dive warning
(if applicable), the current altitude class and
the prohibited altitude class are displayed
for 3 minutes, after which the computer
turns off.
For calculations of desaturation and no-fly time
it is assumed that you are breathing air while
on the surface.
3.5.2 Desaturation time, No-fly
time and No-dive warning
Ascent to altitude 2
prohibited
5 minutes after a dive the Aladin One shows
the desaturation time, the no-fly time, the
no-dive warning (if applicable), the current
altitude class and the prohibited altitude
class – see chapter: Diving with your
Aladin One, section: Prohibited altitude.
No-fly time is the time in hours that should
pass before flying. It is displayed until the
value counts down to 0 hours.
Flying while the Aladin One displays the "do
not fly" icon may lead to serious injury or death
from decompression sickness.
If the "no-dive" warning is visible during the
surface interval, you should not undertake
another dive.

button.
Surface interval
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 One detects a situation of
increased risk (due to the potential of
microbubble accumulation from previous
dives or a CNS O level above 40%), the
2
"no-dive" symbol will appear on the display.
The duration of the no-dive warning is
visible in the dive planner menu. The Aladin
One recommends this as a minimum
surface interval in order to reduce the
number of microbubbles and/or to reduce
the CNS O level below 40%.

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
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.
