Multi-Gas Example Dive (cont.)
6. Max depth - Once NDL hits 0, deco stops will be
needed� Stop requirements display in place of the
Safety Stop information�
7. Ascent - It is safe to ascend to 12 meters� 1 minute
must be spent at that deco stop� While ascending,
the bar graph to the right of the depth shows the
ascent rate� Two chevrons indicate an ascent rate of 6
mpm in this example� All decompression predictions
are made assuming an ascent rate of 10 meters per
minute�
8. Gas Change - All decompression predictions are
made assuming you will switch to the best available
gas on ascent� At 21m, the breathing gas turns yellow
indicating that a better breathing gas is available�
If the switch is not made, deco stop and time
information will be inaccurate�
9. Approaching Deco Stop - As you ascend, the
computer will notify you of an approaching deco stop�
A green check will appear when within 1�8m deeper
than the deco stop depth�
10. Missed Deco Stop - If you ascend shallower than
the decompression ceiling the Deco information will
flash red� If you fail to descend, a missed deco stop
warning will be triggered� Acknowledge and clear
the primary notification by pressing any button�
Re-descend deeper than the stop depth to clear the
flashing text�
10. Deco Clear - Once all decompression obligation
has been cleared, the safety stop will begin if active�
In this case deco clear counter begins counting up
from zero�
