5 Complete a dive with MB levels
A dive with MB levels is completed the same way as a dive without MB levels
(L0) (-> 24), save for the following exceptions:
If the MB level has been reduced during the dive, TEC will display a flashing MB
level symbol and the current MB level for five minutes after reaching the surfa-
ce. The dive is then completed and TEC changes to user mode with the MB
level switching back to the original MB setting.
Repetitive dives and microbubble levels: If during a dive a level stop is being
ignored and the diver starts another descent shortly afterwards, TEC might
immediately request level stops. To complete the dive with the initially set MB
level all level stops must be observed.
4.4 Level stop and deco stop
When the level stop depth equals the
depth of the first obligatory decompres-
sion stop and if you are within
1.5m/5feet of the stop depth itself, TEC
shows
and .
The
indicated duration refers to level stop
duration.
Since level stops are more restrictive
than decompression stops, when all
decompression obligations have been
observed the display changes from
to
only.

Diving with more than one gas mixture
VI
The following chapter deals with the characteristics of diving with more than one gas mixture.
Smart TEC enables you to use up to three different gas mixtures during the same dive. To measure the tank
pressure, each tank requires an individual transmitter. Tank 1 contains the bottom mix, tank 2 contains the
travel mix and tank D contains the deco mix. For dives with a single gas mixture you must use tank 1, for
dives with 2 gas mixtures you must use tanks 1 and D.
