You must carefully read this entire manual before using your Aladin
®
Air Z.
Diving has many inherent risks. Decompression sickness is among the most
serious of those 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 or some other inherent risk of scuba diving. 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!
The Aladin
®
Air Z is a sophisticated dive computer to assist a trained and certified diver in making decisi-
ons concerning dive planning and execution. As with any tool, the Aladin
®
Air Z may be misused if the fol-
lowing safety and operational precautions are not strictly followed. If they are followed, careful use of the
Aladin
®
Air Z 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 is a technically advanced tool based on a mathematical model of decompression
sickness, neither it nor any other diving computer (or table) can exactly monitor the physiological changes
that occur in your body as you dive. In addition, each diver will vary in his or her susceptibility to decom-
pression sickness and each diver will vary in his or her susceptibility to decompression sickness. In additi-
on to this, each individual diver‘s 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 follow all stan-
dard safe diving practices as well as the recommendations contained in this manual.
Guidelines for the use of Aladin
®
Air Z:
The following guidelines for using Aladin
®
Air Z are derived from the latest medical research for diving with
diving computers. Following these guidelines will greatly increase your safety while diving, but cannot gua-
rantee that decompression sickness will not occur.
– The Aladin
®
Air Z is designed for dives made with compressed air only. Do not use the Aladin
®
Air Z for
dives made with nitrox or other mixed gases.
– Due to the danger of nitrogen narcosis do not dive deeper than 40 m. Aladin
®
Air Z does not warn you
in this respect.
– On all dives with the Aladin
®
Air Z, make a safety stop for at least one to three minutes within the 3 to
