Desaturation Time, No-Fly Time And No-Dive Warning - Uwatec Aladin H User Manual

3.5.2 Desaturation time, No-fly
time and No-dive warning
Ascent to altitude 2
prohibited
5 minutes after a dive the Aladin H 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 H, 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 H 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.
To check the elapsed surface interval and
oxygen toxicity, press-and-hold the right
button.

Surface interval
Oxygen toxicity
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 H 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
H 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.
