3 Preparation for a dive with microbubble levels (MB levels)
UWATEC
®
Smart dive computers
3.1 Setting the MB level
To change the MB level Smart must be in user mode.
1. Bridge contacts B and + or B and – until until the symbol for MB levels
appears.
2. Confirm that you wish to change the displayed MB level by bridging B and E.
3. Change MB level by bridging contacts B and + or B and – .
4. Confirm with B and E the selected MB level.
Without confirmation the display will disappear after 3 minutes and your
entries will not be accepted.
Smart will display the
symbol to confirm that an MB level beyond L0 (L1-
L5) has been chosen. If however a level stop is ignored, the new MB level is
permanently shown (-> 25).
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 Smart 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.
The arrow
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 (->18).
• 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, the arrow
NO STOP
disappears and the arrow
LEVELSTOP
appears. The
LEVELSTOP
arrow flashes for 8 seconds and an audible atten-
tion beep goes off. To complete the dive without being reduced to a lower MB
level, all requested level stops must be observed.
To the right of the
LEVELSTOP
arrow, the deepest level stop is displayed in metres/
feet. The display <3m 2:> (<10ft 2:>) means that a level stop of 2 minutes at
a depth of 3 metres (10ft) has to be observed.
When a level stop obligation is finished, the next higher level stop – if present
– is displayed. When all level stops have been observed, the arrow
LEVELSTOP
extinguishes and the arrow
NO STOP
reappears. The indication of time on the
lower right shows the MB no-stop time again.
