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 decompression 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 cannot guarantee that decompression sickness will not occur. ­ The Aladin® Air Z O2 is designed for dives with nitrox (max.99 %O2)and compressed air (21%O2) 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 mixture to be used, even if you are using an Oxy2. Always remember: Setting a wrong mixture causes eit- 4 Uwatec® Aladin® Air Z O2 Safety considerations 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 (decompression sickness, oxygen toxicity). ­ Do not dive deeper than 40 metres. ­ The danger of nitrogen narcosis has to be taken into consideration for all dives regardless of the gas mixture. The Aladin® Air Z O2 gives no warning about this. ­ On all dives with the Aladin® Air Z O2, make a safety stop for at least one to three minutes within the 3 to 5 metre zone. ­ Always make the deepest dive of the day first when repetitive dives are planned, and for each dive make sure that the deepest portion of that dive is done at the beginning of the dive. ­ If your diving cylinder is equipped with a reserve or "J"-type valve, make certain that the reserve function is in an open (down) position. Failure to keep the reserve open will result in the improper calculation of the dive data which depends on tank pressure. ­ All divers using dive computers to plan dives and indicate or determine decompression status must use their own computer which they take with them on all dives. ­ If the Aladin® Air Z O2 fails at any time during the dive, the dive must be terminated, and appropriate surfacing procedures 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. ­ Repetitive dives after exchanging the dive computer: Wait at least 24 hour before you start with the repetitive dive. ­ You MUST be familiar with all signs and symptoms of decompression sickness before using the Aladin® Air Z O2! Seek IMMEDIATE treatment for decompression sickness should any of these signs or symptoms occur after a dive! There is a direct correlation between the effectiveness of treatment and the delay between the onset of symptoms and the treatment for decompression sickness. ­ Always observe the optical and acoustic alarm signals of the Aladin® Air Z O2. Avoid situations of increased risk which are marked with a warning sign in this operating manual. ­ If the ascent arrow appears in the lower display window, start ascending. ­ If the flashing ascent arrow appears in the lower display window, start to ascend immediately. ­ See also page 10, 74-76, 100.

Diving I Uwatec® Aladin® Air Z O2 9 1 Aladin® Air Z O2 ­ Introduction When you dive with an SCR with Oxy2 and Aladin® Air Z O2 you will know your exact decompression, CNS clock status, Oxygen fractions and ppO2 on line and in real time. With Aladin® Air Z O2 paired to a pressure transmitter or Oxy2 you dive more safely than ever before, though you can make more of your diving time thanks to the exact calculation of the gas-supply. In addition, Aladin® Air Z O2 offers an unmatched comfort in carrying and operation. Aladin® Air Z O2 gives you increased safety due to it`s calculation model. All the information necessary for safe diving are combined in one instrument. With the Aladin® Air Z O2 you are ­ due to it`s multi-function ­ ready for the future. The Aladin® Air Z O2 can increase both your diving pleasure and safety by reducing your risk of decompression sickness provided you carefully follow the instructions and guidelines given you in this manual. Unlike previous diving computers, which only base their decompression information on depth and time data, the Aladin® Air Z O2 also considers temperature and diver workload, which are known to be additional risk factors for decompression sickness. By considering these risk factors as well as monitoring your exact supply, the Aladin® Air Z O2 allows you to plan and execute dives with a greater degree of safety than with previous models of decompression computers. The Aladin® Air Z O2 and the Oxy2 are not to be used with closed circuit rebreathers. Please read this operating manual carefully and to the last page. If you are using an Oxy2, you must also carefully read the Oxy2 manual. 2 Aladin® Air Z O2 ­ ...
