3.1 Setting the MB level
To change the MB level Aladin
®
TEC
must be in user mode (
time of day display
).
1. Push
or
until the symbol for MB levels
appears.
2. Confirm that you wish to change the displayed MB level by pushing
.
3. Change MB level by pushing
or
.
4. Confirm the selected MB level with
.
Without confirmation the display will disappear after 3 minutes and your
entries will not be accepted.
Aladin
®
TEC
will display the
symbol to confirm that an MB level beyond L0
(L1-L5) has been chosen. During the dive the MB level is shown by pressing 2x
. If however a level stop is ignored, the new MB level is shown (->33).
MB levels have an influence on the dive planner.
4 Functions during the dive with microbubble levels
4.1 Level stop information
Microbubble (MB) no-stop time
While diving with MB levels L1 to L5 Aladin
®
TEC
will display the MB no-stop time instead of the ordinary
no-stop time. Within the MB no-stop time no level stops are required.
"NO STOP" and the MB level symbol
are visible. The remaining MB no-stop time is shown in minutes.
• Information and alarms for MB no-stop time and ordinary no-
stop time are the same (->24).
• No-stop time relative to L0 is shown by pressing 3x
(see
)
• Regardless of the MB level, we generally recommend to perform
a slow ascent during the last few metres / feet.

Level stop
On entering the level stop phase, "NO STOP" disappears and the arrow
appears. The
arrow flashes for 8 seconds and an audible alarm goes off.
To complete the dive without being reduced to a lower MB level, all requested
level stops must be observed.
The deepest level stop is displayed in metres (feet). The display <2: 3m> (<2: 10ft >)
means that a level stop of 2 minutes at a depth of 3 metres (10ft) has to be
observed. Deco information relative to L0 is shown on an alternate display
(see
).
When a level stop has been finished, the next higher level stop – if present – is
displayed. When all level stops have been observed, the arrow
extinguis-
hes and "NO STOP" reappears. The indication of time shows the MB no-stop
time again.
