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® Sport Plus! WARNING The Aladin® Sport Plus is a sophisticated dive computer to assist a trained and certified diver in making decisions concerning dive planning and execution. As with any tool, the Aladin® Sport Plus may be misused if the following safety and operational precautions are not strictly followed. If they are followed, careful use of the Aladin® Sport Plus 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® Sport Plus 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. 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 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® Sport Plus: The following guidelines for using Aladin® Sport Plus 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® Sport Plus is designed for dives made with compressed air only. Do not use the Aladin® Sport Plus 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. The danger of nitrogen narcosis has to be taken into consideration. The Aladin® 4 Uwatec® Aladin® Sport Plus Safety considerations Sport Plus gives no warning about this. ­ On all dives with the Aladin® Sport Plus, make a safety stop for at least 1 to 3 minutes within the 10 to 15 feet 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. ­ 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® Sport Plus 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 alarm signals of the Aladin® Sport Plus. Avoid situations of increased risk for decompression sickness which are marked with a warning sign in this operating manual. ­ The decompression algorithm contained in the Aladin® Sport Plus only serves for emergency or unintended decompression. ­ Never use the Aladin® Sport Plus for repetitive, "square" dives deeper than 60 feet. A square dive is a dive that is performed for its duration at a uniform depth. ­ You MUST follow the ascent rates as indicated by the Aladin® Sport Plus, 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® Sport Plus! 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® Sport Plus to the limits. Neither the Aladin® Sport Plus, nor any other diving computer or decompression table should be pushed to its limit. 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® Sport Plus. ­ See also page 13-14, 40-42, 65.

The Aladin® Sport Plus is designed for no-stop diving, but also provides the necessary information for safe diving in case of a decompression dive. Aladin® Sport Plus displays all information necessary for safe diving in such a manner that it is easy to survey and to be understood at once. The convincingly simple handling and the high comfort of carrying speak for themselves from the first dive. Read this operating manual carefully and to the last page. 2 Aladin® Sport Plus Your Personal Companion Aladin® Sport Plus considers your individual reactions during the dive and the cooling of your skin. The latest results of medical and technical research were taken into consideration. As a special feature the calculation model also considers the formation of micro-bubbles and the skin temperature. This has led to the development of a unique, adaptive calculation model. Aladin® Sport Plus was exclusively designed for diving with compressed air and especially for diving in the no-stop range. It distinguishes itself from its previous models and other commercial 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 conduct and the ambient conditions. This allows for an even more precise calculation of a modeled risk for decompression sickness which can lead to greater diving safety. · The Aladin® Sport Plus is much more of a personal instrument, which considers the individual conduct of the diver. Different conducts of diving buddies can lead to distinctive differences in the display of the no-stop and decompression information, since risk situations (violations of the diving rules) may have a strong influence by the anticipation of physiological processes. On the other hand, Aladin® Sport Plus "rewards" a diving conduct following the rules with highest diving comfort. · The new calculation model considers for the calculation of the surface intervals and the decompression information for repetitive dives that the physical performance at the surface is smaller than during the dive. 10 I Uwatec® Aladin® Sport Plus 1 Aladin® Sport Plus - Your Personal Companion · The Aladin® Sport Plus uses optical alarms in risk situations or dangerous conduct. I WARNING You must strictly observe all optical alarms due to risk situations or dangerous conduct and take appropriate action based upon those alarms to avoid serious injury or death from decompression sickness! · By using the Aladin® Sport Plus`s logbook, a diver may directly call up information from the last 19 dives. When interfaced with a personal computer, 37 dives and 200 minutes of dive profile in intervals of 20 seconds can be read out. · The dive planner allows the advance planning of no stop dives with readily determinable surface intervals. · Aladin® Sport Plus is designed to be carried on the diver`s wrist. Ease handling, easy to watch and unambiguous arrangement of the data in the display, increase of diving safety without the loss of diving comfort and the possibility of transferring data to a personal computer are the main features of the Aladin® Sport Plus comfort. I Uwatec® Aladin® Sport Plus 11 American 3 The Calculation Model ZH-L8 ADT 3.1 Description The Aladin® Sport Plus uses a new decompression calculation model known as the ZH-L8 ADT. This model uses eight compartments or "tissue" groups with nominal half time periods from 5 to 640 minutes. This model differs considerably from other models by its consideration of the following additional physiological processes: 1. Blood perfusion to the body`s organs is not constant. Skin and muscle tissues are especially subject to changes in blood perfusion, depending on temperature and work load. Changes in blood perfusion to these organs change their nitrogen saturation tolerance. The model used by the Aladin® Sport Plus takes these effects into account and thus the "skin" and "muscle" compartments in the Aladin® Sport Plus show variable half-time periods and saturation tolerances. Decompression information is calculated according to the workload and decrease in skin temperature. The decrease in skin temperature is based upon the water temperature and the dive time. By considering these changes in saturation, the time that must be spent at the surface prior to flying can be considerably lengthened, depending upon the depth, time, and temperature of a dive, as well as the diver`s work during that dive. 2. The decompression model used by the Aladin® Sport Plus considers nitrogen in both its dissolved as well as its gaseous phase (microbubbles). Formation of microbubbles is considered to be a strong indicator of a high risk of decompression sickness. The Aladin® Sport Plus model calculates the formation of microbubbels depending on various assumed influences in arterial and venous blood. In normal, slow ascents, microbubbles form mainly in venous blood. During fast ascents, microbubbles may also form in arterial blood and in the body`s tissues as well. If a particular dive profile may result in the creation of microbubbles according to the Aladin® Sport Plus`s model, decreased bottom time and/or increased decompression times as well as increased "no fly" time will be indicated. · Microbubbles can form if the diver makes too fast an ascent, ignores required decompression stops, or makes repeated ascents during a dive (yo-yo diving). These microbubbles can form in arterial blood as well as in the body`s tissues. If these microbubbles partially impair circulation, the rate of gas diffusion and saturation tolerance for those tissues immediately surrounding this area of impaired circulation are changed. If required, no-stop time, decompression time and -depth will be adjusted in such a way that already existing microbubbles will stop growing. Increased decompression time will also assist those local areas of impaired circulation to desaturate with less risk of decompression sickness. 12 I Uwatec® Aladin® Sport Plus 3 The Calculation Model ZH-L8 ADT I · The calculation of microbubbles results in altered ascent instructions. If microbubbles are assumed to be present based on the data used by the Aladin® Sport Plus, the ascent rate to the surface is reduced to 23 feet/minute. This will help prevent the formation of microbubbles in the arterial circulation and minimizes formation of microbubbles in the venous circulation after the dive. 3.2 Advantages On the first dives following responsible diving procedures, a diver using the Aladin® Sport Plus should never experience a shortened no-stop phase or be required to decompress, although at least a 1 to 3 minute safety stop between 10 and 15 feet is recommended for every dive. If, however, unplanned circumstances arise during the dive which increase the risk of decompression, the Aladin® Sport Plus can, if closely followed, reduce the risk of decompression sickness by increasing decompression time. Some of the more common risk situations are as follows: · · · · · · · Repetitive dives, especially those deeper than 60 feet and those with short surface intervals. Repetitive dives using square dive profiles. Repetitive diving over the course of several successive days. Diving in cold water. Yo-yo diving (repeated descents and ascents to the surface during a given dive). Flying within 24 hours after diving. Excessive ascent rate. American If a diver experiences any of these risk factors while diving, the Aladin® Sport Plus will require decompression in order to help minimize the risk of decompression sickness. WARNING Do not use the Aladin® Sport Plus for planned decompression dives! I Uwatec® Aladin® Sport Plus 13 4 Safety in Diving If signs or symptoms of decompression sickness occur after diving with Aladin® Sport Plus, seek IMMEDIATE treatment at the nearest recompression facility. With its new calculation model the Aladin® Sport Plus is an extremely versatile tool which can increase your diving comfort and safety. As with any diving tool, however, ultimate responsibility for diving safety remains with the individual diver. The same responsible diving practices taught by all diving certification agencies are still absolutely necessary in order to safely dive with the Aladin® Sport Plus. Certain mistakes which may be made by a diver, such as ascending at an excessive rate, going too deep, or staying too long at depth, may be overcome if the diver carefully follows the Aladin® Sport Plus`s corrected ascent instructions. Of course, the Aladin® Sport Plus can do nothing to prevent the occurrence of lung overexpansion injuries or nitrogen narcosis, whose avoidance lies solely with the individual diver. The Aladin® Sport Plus is a highly sophisticated technical instrument which, if used and maintained properly, will have high reliability. Despite that, no dive should be made with an Aladin® Sport Plus without a thorough understanding of decompression theory and dive table use, and every diver must have a set of decompression tables with him on every dive. WARNING Do not use the Aladin® Sport Plus without a set of accepted diving tables with you as a back up decompression tool on every dive. Should decompression sickness occur, whether the Aladin® Sport Plus was used correctly or not, a detailed history of the previous dives may be used to allow a better diagnosis and the most effective treatment for the diver. 14 I Uwatec® Aladin® Sport Plus II Aladin® Sport Plus ­ Survey 1 2 Aladin® Sport Plus System Operation 2.1 II ________________________________________ 16 ________________________________________ Operating for surface functions______________ Switching on display _______________________ Switching off display _______________________ Active backlight ___________________________ 17 17 17 17 18 2.2 Operating modes __________________________22 II Uwatec® Aladin® Sport Plus 15 American 1 The Aladin® Sport Plus-System 1 The dive computer as the central unit of the Aladin® Sport Plus system becomes a valuable aid by a number of additional features: 1 During the dive the Aladin® Sport Plus dive computer supplies all important dive- and decompression information and warnings if necessary.
