Even if you follow the instructions of this manual in a careful fashion, 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! WARNING The Aladin® Air 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 may be misused if the following safety and operational precautions are not strictly followed. [. . . ] 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. The decompression alarm is activated if the decompression stop is ignored. 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 after 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! III Messages: WARNING depth dive time ft DECOSTOP max. depth deco info III Diving with Aladin® Air 43 4 Functions during the Dive Total time of ascent depth dive time As soon as decompression stops are necessary, Aladin® Air shows the total time of ascent. The time of ascent to the first decompression stage and all decompression stops are included. The time of ascent is calculated on the basis of the prescribed ascent rate and a normal workload. Total time of ascent can be subject to change if the ascent rate is not ideal (100%) or with higher workload. S L O W ft DECOSTOP max. depth deco info 4. 6 Tank pressure tank data psi Tank pressure is indicated in the lower display. ­ The tank pressure displayed also serves the calculation of the Remaining bottom time (RBT) and the diver`s performance. swiss made Message: tank data psi WARNING swiss made ­ In case of increased air consumption, Aladin® Air displays a lung symbol in the lower display and an acoustic alarm occurs. Response: In order to prevent additional saturation, reduce exertion and breathe more slowly. III Diving with Aladin® Air 44 4 Functions during the Dive 4. 7 Remaining bottom time RBT RBT is the time left at the current depth until the point of time when the ascent must be started. The RBT is shown in the lower display graphically by a stylized hour-glass as well as in figures (minutes). The RBT is calculated on the basis of the current tank pressure, the temperature, and the dive data so far registered. The RBT is based on the assumption that the tank pressure should amount to at least 580 psi at the end of the dive. Alterations of this are possible (see page 78). depth dive time tank data psi III DECOSTOP NO STOP swiss made max. depth tank data psi deco info swiss made decompression range no-stop time 7min RBT 21min III Diving with Aladin® Air 45 4 Functions during the Dive Never allow the RBT to go below three minutes. If the RBT goes below three minutes there is a danger of insufficient air supply for the ascent as well as an increased risk of decompression sickness and serious injury or death may result! WARNING WARNING Correct calculation of RBT when using a reserve or "J"-type valve is possible only if the reserve function of the valve is in the open (down) position during the dive. ­ The acoustic alarm on exceeding the RBT is suppressed at depths less than 23 ft if Aladin® Air is in the no-stop phase. WARNING ­ If RBT drops below three minutes, an acoustic caution signal is activated, the RBT-symbol appears and the RBT-figure starts blinking. WARNING ­ After the last minute (RBT=0) an acoustic alarm is given every 4 seconds. [. . . ] response Reactivate these attention messages by means of the PC-software DataTalk.

All you need to do is to rinse it carefully with fresh water after each use and to have the batteries changed when needed. To avoid possible problems with your Aladin® Air, the following recommendations will help assure that it will give you years of trouble free service: ­ Avoid dropping or jarring your Aladin® Air.
