Decompression Obligation - Uwatec Aladin H User Manual

The attention message "Level stop ignored"
is activated if the requested level stop is not
observed. An attention beep* sounds and the
STOP arrow, depth and duration of the ignored
level stop begin flashing.
To complete the dive without shifting to a
lower MB level, you must descend to the
prescribed depth immediately!
MB level
reduced
New MB level
The warning "MB level reduced" is activated
if you ascend more than 1.5m/5ft above the
required level stop. The Aladin H reduces the
MB level, an attention beep* sounds and the
new MB level is shown in the lower left corner.
To complete the dive without shifting down
to an even lower MB level the new level stop
must be observed.
* Attention beeps can be suppressed. See
chapter: Settings, section: Switching the
sound on and off.
Total ascent time
The Aladin H displays the level stop
information and the total time of ascent.
This includes the time of ascent as well as
all level stops.

prescribed ascent rate. Total time of
ascent can be subject to change if the
ascent rate is not ideal (100%).

Decompression obligation

The Aladin H calculates and displays level
stops to reduce microbubble formation, but
it also calculates the diver's decompression
data.
WARNING
Avoid decompression dives when diving with
MB levels.
Decompression
obligation
How to avoid decompression stops:
• Check ordinary no-stop time by
pressing the right button until L0
appears.
WARNING
At the beginning of a decompression phase an
attention beep sounds and the symbol flashes
for 8 seconds. In order to prevent a dive with
long decompression stops it is recommended
that you ascend a few meters/feet upon
seeing this message.
If decompression stops become obligatory,
the "DECO" symbol will be displayed. The
total ascent time will now also include a
decompression stop.
Level stop and deco stop
When the level stop depth equals the depth
of the first obligatory decompression stop,
and if you are within 1.5m/5ft of the stop
depth itself, the Aladin H shows STOP
DECO and STOP (level stop). The indicated
duration refers to the level stop duration.
