WARNING 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 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. [. . . ] ­ Decompression time necessary for the prevention of microbubbles can increase massively if the ascent rate is exceeded. ­ At great depth, too slow an ascent may cause heightened saturation of tissues and an extension of both decompression time and total ascent time. At shallow depth, a slow ascent may shorten decompression time because the tissues are desaturating during a shallow, slow ascent.

The arrow <NO STOP> is visible if no decompression stops are necessary. The figures indicate no-stop time in minutes. . depth dive time ­ No-stop display <99:> means remaining time of 99 minutes or more. ­ No-stop time is calculated assuming normal workload and current water temperature. NO STOP max. depth deco info WARNING Response: Messages: There is an acoustic alarm, if no-stop time is less than 1 minute. In this last minute, the no-stop display shows the flashing value <0>. depth dive time In order to prevent a decompression dive, you must ascend a few feet after this message. It is dangerous and an unsafe diving practice to "push" the Aladin® Air Z or any other decompression tool to its limits. Avoid no-stop times of less than three minutes at any given depth. WARNING NO STOP max. depth deco info Decompression values depth dive time ft DECOSTOP max. depth deco info On entering the decompression phase, the arrow <NO STOP> disappears. Right beside the arrow, the deepest decompression stage in feet is displayed. Beside the decompression depth, the decompression time of the displayed stage in minutes appears. The display <30ft 3:> means that a decompression stop of 3 minutes at a depth of 30 ft has to be made. When a decompression stop has been finished, the next higher decompression stop is displayed. When all decompression stops have been made, the arrow <DECOSTOP> extinguishes and the arrow <NO STOP> reappears. The indication of time on the lower right shows the no-stop time again. III Uwatec® Aladin® Air Z 43 4 Functions during the Dive depth dive time WARNING Messages: The decompression alarm is activated if the decompression stop is ignored. Arrow <DECOSTOP> begins flashing and an acoustic alarm is initiated. Due to the formation of microbubbles decompression can increase massively if a decompression stop is ignored. When the surface is reached during the decompression alarm, the arrow <DECOSTOP> continues flashing, in order to point to the risk of a decompression accident. [. . . ] Use soapy water to clean the Aladin® Air Z before using silicone grease and dry it thoroughly. · There are borings in two of the contacts for the reception of the PC interface connection (MemoMouse). · · · · WARNING Take the dive computer or the transmitter to an authorized retailer in order to change the batteries. The actual change of the batteries is made at the manufacturer or the importer. [. . . ]
