® ONE ® SWISS MADE BY UWATEC AG English Operating Manual
Safety considerations You must carefully read and understand this entire manual before using your Aladin® ONE. 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, oxygen toxicity or some other inherent risk of scuba with Nitrox or compressed air.
I Safety considerations Avoid repeated ascents and descents (yo yo diving). Avoid repeated heavy workload while at depth. Plan the dives to be shorter if they are made in cold water. After finishing the decompression or at the end of a no-stop dive, the final stage of the ascent should be as slow as possible.
Introduction Congratulations on purchasing Aladin® ONE and welcome to UWATEC. From now on you will enjoy the assistance of the most extraordinary dive computer - equipped with UWATEC's most innovative technology - while diving. We thank you for choosing Aladin® ONE and we hope you will enjoy safe dives in the future! Further information on UWATEC dive computers and other products by UWATEC can be found on our web page at www.uwatec.com.

II System and operation 1 System description Aladin® ONE displays all important dive and decompression data. Aladin® ONE has a data memory which stores the dive data. The data can be transmitted with an infrared interface (IrDA) and SmartTRAK software to a Windows® personal computer. This software must also be used to configure Aladin® ONE. SmartTRAK software CD is included with the Aladin® ONE Package. Infrared interfaces are available in PC stores.
II II System and operation The following settings may be changed with SmartTRAK: Setting Range Default Page • • • • • • • • • 21-50% O2 no reset / 1 - 48 hrs. metric/imperial on / off ±13 hrs., increments: 15 min.
2 Operation 2.3 Switching on the display • automatically, on submerging in water or when adaptation to atmospheric pressure is necessary; • manually, by "bridging" the water contacts with a moistened finger. DEPTH DIVE TIME NO AMPM DESAT NO STOP DECO STOP STOP CNS O2% S L O W Time of day display DEPTH DIVE TIME NO NO Afterwards the display shows the time of the day, the O2 mix and the temperature. This display is called time of day display.
III Diving with Aladin® ONE III 1 Terminology / Symbols The information on the display of Aladin® ONE varies depending on the kind of dive and the dive phase. Current depth In metres (feet) DIVE TIME CNS O2% Oxygen toxicity CNS O2% Ascent rate (Only while ascending) % Dive phase during which surfacing is allowed without stop. Dive phase during which surfacing is allowed only after decompression stops are completed.
1 Terminology / Symbols 1.3 Nitrox information (O2 information) For dives with compressed air in normal recreational diving, nitrogen is the decisive gas for the decompression calculations. When diving with Nitrox, the risk of oxygen toxicity rises with the increase of the fraction of oxygen and the increase of depth and can limit dive time and the maximum depth.
2 Attention messages and alarms III Aladin® ONE draws the diver’s attention to certain situations and warns the diver of unsafe diving practices. Attention messages and alarms are visual only. English Serious injury or death may result from failing to immediately respond to alarms given by Aladin® ONE. WARNING 2.1 Attention messages 2.2 Alarms Attention messages are communicated to the diver visually by symbols, letters or flashing figures.
3 Preparation for the dive 3.2 Preparation for the dive and function check Check the display: Switch on Aladin® ONE by bridging the water contacts and check the test display: Are all elements of the display activated? Do not use Aladin® ONE if the display does not show all elements.
4 Functions during the dive III 4.2 Phosphorescent display Aladin® ONE is equipped with a phosphorescent display. To excite the phosphorescence, shine your dive torch onto the display for a few seconds. The display will glow for about one minute depending on the strength of your dive torch and how close it was held to the display. 4.3 Dive time Dive time DEPTH DIVE TIME NO STOP The whole time spent below a depth of 0.8m (3 feet) is displayed as dive time in minutes. The time above 0.
4 Functions during the dive 4.6 Ascent rate DEPTH Optimal ascent rate varies depending on depth between 7 and 20 m/min (23 and 66 ft/min). It is displayed in the lower right corner as a percent of the reference variable ascent rate. DIVE TIME NO STOP S L O W WARNING If the ascent rate is greater than 100% of the set value, the black arrow "SLOW" appears. Reduce ascent rate. WARNING If the ascent rate exceeds 140%, the arrow "SLOW" starts flashing. Reduce ascent rate.
III 4 Functions during the dive 4.7 Partial pressure of oxygen (ppO2 max) / Maximum Operating Depth (MOD) The maximum partial pressure of oxygen ppO2 max (1.4 bar) determines the Maximum Operating Depth (MOD). Diving deeper than the MOD will expose the diver to oxygen partial pressures higher than the set maximum level. DEPTH DIVE TIME CNS O2% WARNING Max. Operating Depth MOD The MOD is a function of ppO2 max and the mixture used.
4 Functions during the dive 4.9 Nitrogen loading bar graph The nitrogen loading bar gives a graphical representation of how close to decompression you are. As you absorb nitrogen during the dive, more and more segments of the bar will light up. Depending on your depth, the segments can light up more or less rapidly. 4-5 segments (yellow area): you are approaching decompression. When the no-stop time drops below 3 minutes the 5 segments will start flashing.
III 4 Functions during the dive DIVE TIME DECO STOP CNS O2% The decompression alarm is activated if the decompression stop is ignored. The arrow , the decompression stop duration and decompression stop depth begin to flash. Due to the formation of microbubbles, decompression can increase massively if a decompression stop is ignored.
5 Functions at the surface 5.2 Logbook 5 minutes after a dive Aladin® ONE shows the logbook information of the dive (maximum depth, dive time, temperature, O2%), the surface interval, the "do not dive" icon (if applicable) and the residual nitrogen loading as a bar graph. In addition to the screen logbook, Aladin® ONE records the profiles of about 25 hours of diving. This information can be transferred to a PC with the standard infrared interface (IrDA) and the Windows® software SmartTRAK.
III 6 SOS mode Maximum depth Dive time Activation: automatic If the diver remains above a depth of 0.8m (3 feet) for more than three minutes without observing a prescribed decompression, the computer will automatically switch into SOS mode after the dive. NO While in SOS mode, the computer cannot be used for diving. English NO DESAT The SOS mode will be unlocked after 24 hours. Diving within 48 hours after the end of an SOS mode will result in shorter no stop times or longer decompression stops.
7 Diving in mountain lakes 7.1 Altitude ranges Altitude symbol Desaturation information NO Time interval since the last change in altitude class Aladin® ONE measures the atmospheric pressure every 60 seconds even while the display is switched off. If the computer detects a sufficient increase in altitude, it switches on automatically and indicates the altitude symbol, the adaption time (desaturation time) as a bar graph and the time interval since the change in altitude class.
IV Appendix 1 Technical information IV with decompression information: sea level up to approx. 4000 m (13120 ft); w/o decompression, automatic gauge mode (at any altitude) Max. displayed depth: 120 m (395 ft), resolution between 0.8 m and 99.9 m: 0.1 m, >99.9 m: 1 m The resolution in feet is always 1 foot. • Do not dive deeper than the limits given by the chosen fraction of oxygen WARNING (nitrogen narcosis, oxygen toxicity). • Never dive deeper than your training qualification (experience) allows you.
IV Appendix WARNING Never touch the metal surface of the battery with bare fingers. The two battery poles must never be short circuited. Procedure: To replace the battery you need a coin or the SCUBAPRO universal tool and a clean cloth. WARNING 3 • A leaking battery cap may lead to the destruction of Aladin® ONE by water seeping in or cause Aladin® ONE to switch off without prior notice. • Always open the battery compartment in a dry and clean environment.
