The Aladin

Pro Ultra calculates according to the planned surface interval the
expected production of microbubbles. The diver should increase the surface
interval if <Atn> (Attention) is displayed. This will reduce the risk of micro bub-
ble production in the pulmonary system.
• By repeatedly recalling of the diveplan with varying surface intervals the mini-
mum interval can be determined.
• Diving with the display <Atn>, a clear shortening of the no-stop time and/or an
extension of decompression has to be expected.
• If a dive is made during <Atn>-time, the <Atn>-time following the dive can
increase considerably.
Making a repetitive dive when <Atn> is displayed will increased your risk of
serious injury or death from decompression sickness!
