Oceanic Dive Computer Pro Plus 2 Operating Manual page 59

The Pro Plus 2 cannot calculate decompression times for Stop
Depths much greater than 60 feet (18 meters) and offers no
indication of how much time spent underwater would result in
the need for a greater Stop Depth.
If the Decompression obligation requires a Ceiling
Stop Depth between 60 feet (18 meters) and 70
feet (21 meters), the Tissue Loading Bar Graph will flash.
Total Ascent Time will still be displayed.
You must ascend to just deeper than, and stay as close as
possible to, 60 feet (18 meters) without causing the Total
Ascent Time display to flash. When the Required Stop Depth
indicates 50 FT/ 15 M, etc., you can ascend to those depths
and continue decompressing.
If you descend deeper than 330 feet (99.9
meters), the accumulated Tissue Loading Bar Graph seg-
ments will flash, and the Current Depth and Max Depth
displays will only indicate 3 dashes ( - - -).
