4 Functions during the dive with MB levels
V UWATEC Aladin TEC 2G
V
The attention message "Level stop ignored" is
activated if the requested level stop is not observed.
An attention beep* goes off and the arrow
STOP
, the
depth and duration of the ignored level stop begin
flashing.
To complete the dive without being reduced to a
lower MB level, you must descend to the prescribed
depth immediately!
The warning "MB level reduced" is activated if
the diver ascends more than 1.5m (5ft) above the
required level stop. Aladin reduces the MB level, an
attention beep* goes off and the new MB level is
shown in the lower left corner.
To complete the dive without being further reduced
to an even lower MB level the new level stop must
be observed.
* Attention beeps can be suppressed with
" set 1 " (->47) or via
SmartTRAK.

4.2 Total time of ascent
Aladin displays the level stop information and the total time of ascent. This
includes the time of ascent as well as all level stops.
The total time of ascent is calculated on the basis of the prescribed
ascent rate. Total time of ascent can be subject to change if the
ascent rate is not ideal (100%) .
4.3 Decompression obligation
Aladin calculates and displays level stops to reduce microbubble formation, but
it also calculates the diver's decompression data.
Avoid decompression dives when diving with MB
levels.
How to avoid decompression stops:
• Check ordinary no-stop time by pushing until L0 appears.
• Observe the nitrogen loading bar (it is relative to L0) ->26, ->33
• If the nitrogen loading bar flashes (less than 3 minutes to deco): ascend
slowly a few metres/feet.
At the beginning of a decompression phase an
attention beep goes off and the
DECO
symbol
flashes for 8 seconds.
In order to prevent a dive with long decompression stops it is recommend-
ed that you ascend a few metres/feet on seeing this message.
If decompression stops become obligatory, the
DECO
symbol will be displayed.
The total ascent time will now also contain a decompression stop.
