WARNING 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 decompression tool to assist a trained and certified diver in making decisions concerning dive planning and execution. As with any tool, the Aladin® Air Z 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 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 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: The following guidelines for using Aladin® Air Z are derived from the latest medical research and the recommendations of the American Academy of Underwater 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 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. ­ In accordance with the recommended maximum diving limit of all instructional agencies, do not dive deeper than 130 feet. ­ Do not use the Aladin® Air Z for planned decompression diving. The decompression algorithm contai- 4 Uwatec® Aladin® Air Z Safety considerations ned in the Aladin® Air Z should be used only for emergency or unintended decompression. ­ On all dives with the Aladin® Air Z, make a safety stop for at least one to three minutes within the 10 to 15 feet zone. ­ Never use the Aladin® Air Z for repetitive, "square" dives deeper than 60 feet. A square dive is a dive that is performed for its duration at a uniform depth. ­ 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 is in an open (down) position. Failure to keep the reserve open will result in the improper calculation of dive data depending 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 fails at any time during the dive, the dive must be terminated, and appropriate surfacing procedures (including a slow ascent and a 3 to 5 minute safety stop) 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. ­ Always observe the optical and acouctic alarm signals of the Aladin® Air Z. Avoid situations of increased risk for decompression sickness which are marked with a warning sign in this operating manual. ­ You MUST follow the ascent rates as indicated by the Aladin® Air Z, and should the computer fail for any reason, you must ascend at a rate of no greater than 30 feet per minute. ­ You MUST be familiar with all signs and symptoms of decompression sickness before using the Aladin® Air Z! 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. ­ Never dive the Aladin® Air Z to the limits. Neither the Aladin® Air Z, nor any other diving computer or decompression table should be pushed to its limits. Give yourself a margin of safety by always leaving at least a few minutes in the "no-stop" box before making your ascent. ­ Avoid repeated ascents and descents (yo-yo diving) while using the Aladin® Air Z. ­ See also page 54-55 and 84.

The good feeling to have the highest possible safety and freedom to move. A dive computer, which constantly controls the data of your dive and your individual behavior, meets these requirements. Aladin® Air Z watches over the gas saturation of your body without interruption. With Aladin® Air Z you dive more safely than ever before, though you can make more of your diving time thanks to the exact calculation of the air-supply. In addition, Aladin® Air Z offers an unmatched comfort in carrying and operation. Aladin® Air Z gives you headway in safety due to the new calculation model. All informations necessary for safe diving are combined in one instrument. The Aladin® Air Z can increase both your diving pleasure and safety by reducing your risk of decompression sickness provided you carefully follow theinstructions 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 also considers temperature anddiver workload, which are known to be additional risk factors for decompression sickness. By considering these risk factors as well as monitoring your exact air supply, the Aladin® Air Z allows you to plan and execute dives with a greater degree of safety than with other models of decompression computers. Please read this operating manual carefully and to the last page. 2 Aladin® Air Z ­ Your Personal Companion By considering your individual depth and time profile, as well as workload and water temperature, the Aladin® Air Z can be considered a personal diving control instrument. Relying on the latest results of medical and physiological research for its decompression modeling, the Aladin® Air Z differs from other diving computers in a number of significant ways: · The ZH-L8 ADT decompression calculation model considers eight body tissues as well as the diver`s workload and ambient temperature. This allows for an even more precise calculation of a modeled risk for decompression sickness which can lead to greater diving safety. · Tank pressure readings are transmitted to the Aladin® Air Z by means of a transmitter. Faulty transmission of data between the transmitter and Aladin® Air Z is prevented by a number of precautions, and tank pressure can be easily checked at any time. B ...
