If the display <Atn> (=attention) is visible instead of the depth during the surface interval (surface- max. depth deco info mode), the diver should extend the surface interval.

If the computer depth dive time detects a higher altitude section, it switches into surface-mode automatically. Desaturation time indicated at this moment refers to adaptation time at this altitude.

But if an altitude section is displayed at sea level or the altitude informations of two computers differ by more than one altitude section (e.g. section 2 instead of 0), there may be a defect of the computer.

  • Page 51: Minimizing Risks On Repetitive Dives

    ® If the dive includes a risk situation, Aladin Pro reacts automatically and appropriately to the situation. A change of decompression is indicated if it is actually necessary to minimize the risk. The diver can further reduce the risk through sensible conduct on the next dive and at the same time prevent long decompression stops.
  • Page 52 1 Diving at Low Risk with Aladin ® Situation: The diver ascends much too rapidly: Reaction of computer: The model calculates the formation of bubbles due to the excessively rapid ascent. No-stop time is shortened or a longer (and eventually at greater depth) decom- pression prescription is displayed in order to assure sufficient decompression.
  • Page 53 1 Diving at Low Risk with Aladin ® Situation: The diver disregards the prescribed decompression depth for some time. Reaction of computer: The model calculates the formation of bubbles due to ignoring decompression. A longer (and eventually at lower depth) decompression is displayed in order to assure sufficient time for desaturation.
  • Page 54 1 Diving at Low Risk with Aladin ® Situation: The diver is exposed to exertion for a long period (e.g. in a current). Reaction of computer: An extension of the decompression is indicated, if the muscle tissues are relevant for the decompression of the dive.
  • Page 55 (e.g. on organized diving trips from a boat). Reaction of computer: Aladin ® Pro calculates a more conservative no-stop time or decompression prescription in order to allow nitrogen in the vicinity of bubbles enough time for desaturation. Recommended action of the diver During the dive: Be careful to have a profile 'low in bubbles' on your next dive (limit depth to 25 m max., slow ascent).

The no-stop time for every 3- metre-increment is displayed for about 3 seconds (scrolling no-stop times).
