Safety considerations

You must carefully read and understand this entire manual before using your Aladin
®
Pro Ultra.
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
®
Pro Ultra!
The Aladin
®
Pro Ultra is a decompression tool to assist a trained and certified diver in making decisions
concerning dive planning and execution. As with any tool, the Aladin
®
Pro Ultra may be misused if the fol-
lowing safety and operational precautions are not strictly followed. If they are followed, careful use of the
Aladin
®
Pro Ultra 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
®
Pro Ultra is a technically advanced tool based on mathematical models of decompres-
sion 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. In addition 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 respon-
sibly and to carefully follow all standard safe diving practices as well as the recommendations contained
in this manual.
Guidelines for the use of Aladin
®
Pro Ultra:
The following guidelines for using Aladin
®
Pro Ultra 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
®
Pro Ultra is designed for dives with nitrox (max.50 %O
2
)and compressed air (21%O
2
) only.
Do not use the Aladin
®
Pro Ultra for dives made with 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
