Situation 3:
The diver is physically exerting himself or herself, (e. g. swimming
against the current).
Reaction of computer:
A shorter RBT or an extension of decompression time. See page 47 and 64.
Recommended response of the diver
During the dive:
• Avoid further physical exertion if possible. Relax.
• Frequently check the RBT (pressure transmitter only) or oxygen fraction (Oxy2
only) and decompression information on your Aladin

.
• RBT may decrease considerably. Decompression time may increase considerably.
After the dive:
Refrain from heightened physical exertion on your next dive.
Increase your surface interval.
Situation 4:
It is very unlikely to have a surface interval long enough to clear the
<Atn> prior to the next dive during an organized dive trip from a boat.
This previous buildup of nitrogen must be taken into consideration for
the next dive.
Reaction of computer:
Aladin

calculates a shorter no-stop time or longer decompression
prescription to reduce the risk of decompression sickness. See page 69.
Recommended response of the diver
During the dive:
Dive conservatively on all repetitive dives. Limit your maximum depth to no
more than 25 metres at the very beginning of the dive, do not allow the RBT
to go below three minutes, and make a very slow ascent.
After the dive:
Before the next dive, plan a sufficiently long surface interval (<Atn> display
should disappear).
