How To Navigate The Aladin H At The Surface; Checking The Desaturation Time; Checking The Surface Interval - Uwatec Aladin H User Manual

Time of day display:
The Aladin H switches on:
• Automatically, upon submerging in
water or when triggered by a change in
atmospheric pressure.
• Automatically when pressure at the HP
hose is detected.
• 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 H may indicate
the "Do not fly" icon, "Do not dive" icon or
"Altitude" icon or a combination of the icons
depending on the situation.

NOTE: Without active use the Aladin
H's display automatically reverts to
the time of day display, and after 3
minutes the computer switches off.

Starting from the time of day display you
can enter into different menus.
2.2.6 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.

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
