depths slightly deeper than 40 feet in some situations. If this happens,
descend to the shallowest depth below 40 feet where the flashing stops.
After waiting until the Tissue Loading Bar Graph recedes into the 30 foot
zone, you can then ascend to not less than 30 feet and continue decompress-
ing. After more time, the bar graph will recede into the 20 and then 10 foot
zones after which the diver can ascend to less than 20 or 10 feet respectively.
After DEC Time reaches zero and the Tissue Loading Bar Graph recedes into
the yellow Caution Zone (C.Z.), you can surface. However, to add a
greater margin of protection, Oceanic strongly recommends that
you wait until the segments are well within the green No Decom
zone, unless a low air condition requires you to surface. Five minutes
after reaching the surface, the Pro will enter the Immediate Violation Mode
and will then revert to Gauge Mode (see page 37).
Delayed Violation #2 -
Spending More than 5 Minutes Above Decompression Ceiling
If you stay above the decompression ceiling for more than five minutes,
you will enter Delayed Violation Mode. If you descend back beneath the
ceiling after this five minute time window, it is still possible to get back to the
surface with the assistance of the DataMax Pro. As previously described, you
would then need to follow the ceiling toward the surface as the Tissue Load-
ing Bar Graph recedes toward the Caution Zone. Upon reaching zero decom-
pression time remaining, you should continue decompressing until the bar
