1 Planning a no-stop dive
With the contacts B and – or B and – you can select the dive planner at the surface.
NO
The microbubble warning
and its duration are dis
-
played if Smart detects an
increased risk due to the
accumulation of micro
-
bubbles.
Enter the dive planner with B and E.
The input window for the time interval is displayed
if there was a remaining desaturation (DESAT)
before the dive planner has been selected. This
surface interval between now and the beginning of
the dive can be changed with the contacts B and +
or B and – in steps of 15 minutes.
NO
If a microbubble warning (no dive) and its
duration has been displayed, Smart proposes
this time – rounded up to the next 15 minutes –
as surface interval. If the proposed interval is
shortened, the microbubble warning appears.
With B and E you confirm the displayed interval (if applicable), then Smart
starts scrolling the no-stop times. The no-stop times are displayed in 3 metre
increments (10 ft) and are displayed for every increment for about 3 seconds.
The process starts at 3 metre (10 feet).
If a microbubble level has been selected (L1 to 5), Smart shows the micro-
bubble no-stop time instead of the no-stop time.
Depths deeper than the MOD for the selected gas (O
2
mix) are not displayed.
NO
On page 20 you will find further information and safety considerations
regarding the microbubble warning.

WARNING
• selected fraction of oxygen (O
2
% Mix)
• selected microbubble level
• water temperature of the most recent dive
• altitude range (if any)
• status of saturation at the time the dive planner is selected
• assuming a normal workload of the diver and observance of the prescribed
ascent rates.
If two or more divers using computers are planning a dive, planning for all
divers has to be based on the dive computer showing the shortest no-stop
times. Failure to do this may lead to serious injury or death from decompres
-
sion sickness.
Smart is equipped with a dive planner which allows the planning of no-stop
dives with freely determinable surface intervals.
