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. [. . . ] 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. The SOS-mode is activated 3 minutes after the dive if corrective action is not taken. If the total (cumulative) duration of the decompression alarm is longer than a minute, it is entered in the logbook. Response: Descend to the prescribed decompression depth immediately! ft DECOSTOP max. depth deco info Total time of ascent depth dive time As soon as decompression stops are necessary, Aladin® Air Z shows the total time of ascent. [. . . ] The computer is checked for its technical functioning at the same time. Do not attempt to have the batteries changed by anyone other than an authorized dealer. 80 IX Uwatec® Aladin® Air Z 2 Technical Information Operating altitude: with decompression information: without decompression information: IX sea level up to approx. 13300 ft unlimited Operating depth: no limitation in the permitted range of diving with compressed air no limit for recreational dives. In accordance with the recommended maximum diving limit of all instructional agencies, do not dive deeper than 130 feet. WARNING Instrument operating range: 2 to 380 feet Clock: Power supply: Life of the battery: quartz timer, display up to 199 minutes Special battery Uwatec LR07 (standard values) For an average diving time of 60 minutes and a surface interval of 20 hours after every dive: Number of dives per year 50 100 150 300 dive computer (years) 7 5. 5 4 2. 5 transmitter (years) 11 9. 5 8 6 Operating temperature: 14°F to +122°F IX Uwatec® Aladin® Air Z 81 3 Conversion of Tank Pressure Tank pressure indicated in the lower display may diverge from the information given by a manometer/pressure gauge. Aladin® Air Z displays pressure always converted to a temperature of 68°F, whereas the mechanical pressure gauge displays the actual pressure influenced by temperature. [. . . ]
