Operating Manual Aladin®Pro Nitrox
You must carefully read this entire manual before using your Aladin®Pro Nitrox.
TheAladin®Pro Nitroxisadecompression tool to assist a trained and certified diver in making decisions
concerning dive planning and execution. As with any tool, the Aladin®Pro Nitrox may be misused if
the following safety and operational precautions are not strictly followed. If they are followed, careful
useoftheAladin®Pro Nitroxcanincrease your diving enjoyment andreduceyourriskofdecompression
sickness. If they are not, you will be placing yourself at serious risk for decompression sickness.
WhiletheAladin®ProNitroxisatechnicallyadvancedtoolbasedonbiophysicalmodelsofdecompression
sickness and oxygen toxicity, neither it nor any other diving computer (or table) can actually monitor
the physiological changes that occur in your body as you dive. In addition, each diver will vary in his or
hersusceptibility to decompressionsickness.Notonlythat, but each individualdiver‘sownsusceptibility
mayvaryfromday today.Combinedwith the fact that decompressionmodelling is an inexact science,
and of necessity must be based at least partly on certain unproven assumptions, it is incumbent upon
you, the individual diver, to dive responsibly and to carefully follow all standard safe diving practices as
well as the admonitions contained in this manual.
Safety considerations
WARNING
Diving has many inherent risks. Even if you follow the instructions of
this manual in a careful fashion, it is still possible that you may be
seriously injured or die from decompression sickness, oxygen toxicity or
some other inherent risk of scuba nitrox. Unless you are fully aware of
these risks and are willing to personally accept and assume
responsibility for those risks, do not use the Aladin®Pro Nitrox!

Operating Manual Aladin®Pro Nitrox
Guidelines for the use of Aladin®Pro Nitrox:
The following guidelines for using Aladin®Pro Nitrox are derived from the latest medical research and the
recommendationsoftheAmericanAcademyofUnderwaterSciencesfordivingwithdivingcomputers.Following
theseguidelineswillgreatlyincreaseyoursafetywhilediving,butcannotguaranteethatdecompressionsickness
will not occur.
– The Aladin®Pro Nitrox is designed for dives made with nitrox and compressed air (21% O2) only. Do not use
the Aladin®Pro Nitrox for dives made other mixed gases.
– It is absolutely necessary to check the set mixture before each dive and to compare it to the gas mixture
actually used.
Always remember: Setting a wrong mixture cause either insufficient decompression calculations or a too
low calculation of the oxygen-toxicity!
– In accordance with the recommended maximum diving limit of all instructional agencies, do not dive
deeper than 130 feet.
– Always check the diving limits given by the used share of oxygen.
– DonotusetheAladin®Pro Nitroxforplanneddecompressiondiving.Thedecompressionalgorithmcontained
in the Aladin®Pro Nitrox should be used only for emergency or unintended decompression.

Safety considerations

Operating Manual Aladin®Pro Nitrox
– On all dives with the Aladin®Pro Nitrox, make a safety stop for three to five minutes within the ten to thirty
feet zone.
– Never use the Aladin®Pro Nitrox for repetitive, “square“ dives deeper than 60 feet. A square dive is a dive
that is performed for its duration at a uniform depth.
– Always make the deepest dive of the day first when repetitive dives are planned, and for each successive
dive make sure that the deepest portion of that dive is done at the beginning of the dive.
– All divers using dive computers to plan dives and indicate or determine decompression status must use
their own computer.
– If the Aladin®Pro Nitrox fails at any time during the dive, the dive must be terminated, and appropriate
surfacingprocedures(includingaslowascentanda3to5minutesafety stop) should be initiated immediately.
– On any given dive, all divers in a buddy group must follow the most conservative dive computer for that
particular dive.
– You should not dive for a period of twenty-four hours before activating the Aladin®Pro Nitrox to use it to
plan or control your diving.

Operating Manual Aladin®Pro Nitrox
– You MUST follow the ascent rates as indicated by the Aladin®Pro Nitrox, and should the computer fail for
any reason, you must ascend at a rate of no greater than 60 feet per minute.
– You MUST be familiar with all signs and symptoms of decompression sickness before using the Aladin®Pro
Nitrox! Seek IMMEDIATE treatment for decompression sickness should any of these signs or symptoms
occur after a dive! There is a direct correlation between the efficacy of treatment and the delay between
the onset of symptoms and the treatment for decompression sickness.
– Alwaysobservethe optical and acousticalarmsignals of the Aladin®ProNitrox.Avoidsituations of increased
risk which are marked with a warning sign in this operating manual.
– Never dive the Aladin®Pro Nitrox to the limit. Neither the Aladin®Pro Nitrox, nor any other diving computer
or decompression table should be pushed to its limit. Give yourself a margin of safety by always leaving at
least a few minutes in the “no-stop“ box before making your ascent.
– Avoid repeated ascents and descents (yo-yo diving) while using the Aladin®Pro Nitrox.
