ALADIN ONE USER MANUAL
The Aladin One switches on:
• Automatically, upon submerging in
water or when triggered by a change in
atmospheric pressure.
• Manually, by pushing and holding either
the left or right button.
If switched on with the left button, all
display segments appear for 5 seconds.
Afterwards, the display shows the time of
day, the date and a scrolling SCUBAPRO
which is quickly replaced by the day of the
week. This is referred to as the “time of
day” display.
In the time of day display, if there is
remaining saturation from the last dive or
from a change of altitude, the Aladin One
may indicate the “Do not fly” icon, “Do not
dive” icon or “Altitude” icon or a combination
of the icons depending on the situation.
F
NOTE: Most navigation descriptions in
this manual start from the time of day
display. At the surface, the Aladin One
returns automatically to this display
.
F
NOTE: When the Aladin One is
in a state of rest, no information
is displayed but the atmospheric
pressure continues to be monitored.
If a change in altitude classes is
detected, the Aladin One automatically
switches on for 3 minutes
.
F
NOTE: Without active use the Aladin
One’s display automatically reverts
to the time of day display, and after 3
minutes the computer switches off
.

How to navigate the Aladin
One at the surface
Starting from the time of day display you
can enter into different menus.
2.2.5
Checking the desaturation
time
From the time of day display you can check
the desaturation time* with a press-and-
hold of the right button. Desaturation time
is determined either by oxygen toxicity,
nitrogen saturation or the regression
of microbubbles, depending on which
requires the longer time.
*Desat time is displayed only if there is
remaining saturation due to the last dive or
a change of altitude.
WARNING
For calculations of desaturation and no-fly
time it is assumed that you are breathing air
while on the surface.
2.2.6
Checking the surface interval
From the time of day display you can check
the surface interval with a press-and-hold
of the right button (taking you directly to the
dive menu) and then another press-and-
hold (taking you to surface interval).
Surface interval is the elapsed time since
the end of your last dive; it is displayed as
long as there is remaining saturation.
