You must carefully read and understand this entire manual before using your Aladin
®
Air Z O2.
Diving has many inherent risks. Even if you follow the instructions of this
manual in a careful manner, 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 or compressed air. 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
®
Air Z O2!
The Aladin
®
Air Z O2 is a decompression tool to assist a trained and certified diver in making decisions (there
is no dive planner available in the Air Z O2). As with any tool, the Aladin
®
Air Z O2 may be misused if the
following safety and operational precautions are not strictly followed. If they are followed, careful use of
the Aladin
®
Air Z O2 can increase your diving enjoyment and reduce your risk of decompression sickness.
If they are not, you will be placing yourself at serious risk for decompression sickness.
While the Aladin
®
Air Z O2 is a technically advanced tool based on mathematical models of decompressi-
on 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 her sus-
ceptibility to decompression sickness. In addition, each diver will vary in his or her susceptibility to decom-
pression sickness and each individual divers own susceptibility may vary from day to day. Combined with
the fact that decompression modelling is an inexact science, and must be based to some extend on certain
unproven assumptions, it is emphasis on you, the individual diver, to dive responsibly and to carefully fol-
low all standard safe diving practices as well as the recommendations contained in this manual.
Guidelines for the use of Aladin
®
Air Z O2: The following guidelines for using Aladin
®
Air Z O2 are
derived from the latest medical research and the recommendations of the American Academy of Under-
water Sciences for diving with diving computers. Following these guidelines will greatly increase your
safety while diving, but cannot guarantee that decompression sickness will not occur.
The Aladin
®
Air Z O2 is designed for dives with nitrox (max.99 %O
2
) and compressed air (21%O
2
) only.
Do not use the Aladin
®
Air Z O2 for dives made with other mixed gases.
It is essential to check the set mixture or O2 fraction before each dive and to compare it to the gas mix-
ture to be used, even if you are using an Oxy2. Always remember: Setting a wrong mixture causes eit-
her insufficient decompression calculations or a too low calculation of the oxygen-toxicity!
Always check the diving limits considering the oxygen content and standard sports diving procedures
