33
meters) where the flashing stops.
After waiting until the TLBG recedes into the 30 FT (9 M) zone, the diver
can then ascend to not less than 30 feet (9 meters) and continue decompres-
sion. After more time, the TLBG will recede into the 20 FT (6 M) and then 10
FT (3 M) zones after which the diver can ascend to not less than 20 or 10 feet
(6 or 3 meters) respectively. After Total Decompression Stop Time reaches
zero and the TLBG recedes into the yellow Caution Zone (C.Z.), the diver 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. After 5
minutes of surface time, the PRODIGY will enter an Immediate Violation
and will then revert to the Gauge Mode (see page 35) for 24 hours.
#2 - Spending More than 5 Minutes Above Decompression Ceiling
If you stay above the decompression ceiling for more than 5 minutes, you
will enter Delayed Violation Mode. At this time the TLBG will flash (Fig. 25,
page 32). If you descend back beneath the ceiling after this 5 minute time
window, it is still possible to get back to the surface with the assistance of the
PRODIGY. As previously described, you would then need to follow the ceiling
toward the surface as the TLBG recedes toward the Caution Zone. Upon
reaching zero decompression time remaining, you should continue decom-
pressing until the TLBG segments are well inside of the green No Decom
