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. [. . . ] Desaturation time is continually indicated until the next dive or until it reaches zero. The display is switched off to save energy three minutes after the last manipulation is made (surface-sleep-mode). max. depth deco info In some cases, desaturation times with the Aladin® Sport are considerably longer than those of its predecessors. This is because the calculation model assumes reduced physical activity at the surface (therefore less nitrogen off gassing) and uses shorter half-times. If desaturation time reaches zero, the "tissue" models of the Aladin® Sport are desaturated and it switches into the sleep-mode. 34 III Diving with Aladin® Sport 5. Functions at the Surface 5. 3 No fly time depth DO NOT FLY dive time h The waiting period until the next flight is indicated as follows:<DO NOT FLY>. Beside this indicator is the time in hours that should pass before a flight. Next to that display the time in hours until it is considered appropriate to fly is displayed (because of recalibrated desaturation time). DESATURATION h III max. depth deco info WARNING Flying while the Aladin® Sport displays <DO NOT FLY> may lead to serious injury or death from decompression sickness. III Diving with Aladin® Sport 35 5. Functions at the Surface 5. 4 Warning of bubbles depth DO NOT FLY dive time h DESATURATION h max. depth deco info Through repetitive dives microbubbles may accumulate in the lungs if the surface interval is not long enough. Ignoring decompression stops or an excessive ascent rate can also lead to bubbles in tissues. In order to reduce the risk of decompression sickness for future repetitive dives, the surface interval should be planned long enough to reduce the risk of decompression sickness. If Aladin® Sport calculates that the formation of microbubbles may occur during the surface interval, it will advise a diver to extend the surface interval. If the display <Atn> (=attention) is visible instead of the depth during the surface interval (surfacemode), the diver should extend the surface interval. Through the extension of the interval the diver may prevent a high concentration of bubbles in the lungs during the planned dive and avoids a situation of higher risk. ­ If the dive has to be made during <Atn>-time, the <Atn> time of the following dive can increase considerably. ­ If the dive is made in spite of the display <Atn>, the diver must cope with a clearly shorter no-stop time and an extension of decompression. 36 III Diving with Aladin® Sport 5. Functions at the Surface depth dive time DESATURATION h Aladin® Sport measures the atmospheric pressure even while in sleep-mode. If the computer detects a higher altitude, it switches into surface-mode automatically. Desaturation time indicated at this moment refers to adaptation time at this altitude. If diving starts within this adaptation time, Aladin® Sport treats it as a repetitive dive, since the body still has a higher saturation. max. [. . . ] ­ Do not allow your Aladin® Sport to be exposed to direct, intense sunlight. ­ Rinse your Aladin® Sport thoroughly with fresh water after each dive. ­ Do not store your Aladin® Sport in an air-tight area; make sure there is free ventilation. ­ If there are problems with operating the contacts, the surface of your Aladin® Sport housing can be treated with silicone grease.
