Bar Graphs
As your Depth and Dive Time increase during a dive, the Nitrogen Bar Graph will fill with seg-
ments (counter clockwise green toward red) to represent nitrogen loading. Segments of the As-
cent Rate Indicator fill (left to right) and recede (right to left) as your Ascent Rate increases (and
decreases) throughout the dive.
WARNING: Every effort should be made to keep each of the bar graphs in
the green throughout your dives.
NO DECOMPRESSION DIVE MODE SAFETY STOP
Upon ascending to 20 feet (6 meters) on any No Decompression dive in which Depth exceeded
30 feet (9 meters), a non mandatory Safety Stop screen appears with a countdown timer begin-
ning at 3:00 (min:sec) and counting down to :00. There is no penalty if you surface during the
countdown period.
In the event that you descend below 30 feet (9 meters) during the countdown, the No Deco Main
screen replaces the Safety Stop screen which reappears upon ascent to 20 feet (6 meters).
