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 inju-
red or die from decompression sickness, oxygen toxicity or some other inhe-
rent 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 O
2 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
susceptibility to decompression sickness. In addition, each diver will vary in his or her susceptibility to
decompression sickness and 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 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 for diving
with diving computers. Following these guidelines will greatly increase your safety while diving, but can-
not guarantee that decompression sickness will not occur.
– The Aladin
®
Air Z O
2 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-
