3 Preparation for a dive with Microbubble-Levels (MB-levels)
IV 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 + 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. Confirmation 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. During the dive the MB-level itself will only be shown if a
level-stop has been ignored (see p. 28).
MB-Levels do have an influence on your dive planner, your desaturation and
no-flight time. They can also alter the range of altitudes a dive can safely carry
out.
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
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 (see p. 18).
• In spite of the MB-level program, we generally recommend to
perform a slow ascent during the last few metres / feet.
Level-stop
On entering the level-stop phase, the arrow
disappears and the
arrow
appears. The
arrow flashes for 8 seconds and an acou-
stic alarm is initiated. To complete the dive without being reduced to a deeper
MB-level, all requested level-stops must be observed.
To the right of the
arrow, the deepest level-stop is displayed in met-
res/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 made.
When a level-stop has been finished, the next higher level-stop – if necessary –
is displayed. When all level-stops have been made, the arrow
extin-
guishes and the arrow
reappears. The indication of time on the
lower right shows the MB no-stop time again.
