Safety considerations You must carefully read and understand this entire manual before using your Aladin TEC 2G. 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.
• 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 TEC 2G 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. Aladin TEC 2G enables you to use two different gas mixtures during the same dive. However, for an easy reading this manual mainly refers to dives with a single gas mixture. Information for diving with two gas mixtures is marked with or has been summarised in special chapters.

Aladin displays all important dive and decompression data and has a memory which stores the full dive data. The data can be transmitted with an infrared interface (IrDA) and SmartTRAK software to a Windows® personal computer. SmartTRAK software CD is included with the Aladin package. Infrared interfaces are available in PC stores; a list of recommended interfaces is available on our website (www.scubapro-uwatec.com).
2 Operation 2.2 Water contacts On submerging in water the water contacts switch on Aladin automatically. WARNING If you have chosen the option "Water contacts off" ("set 1", ->47), Aladin will turn on with a delay of up to 1 minute into the dive. This will affect functioning of the computer. Make sure that the computer is on before starting the dive. 2.3 SmartTRAK With SmartTRAK you can configure Aladin, transfer dive data to a personal computer and graphically display the data.
2 Operation II The following settings may be changed with SmartTRAK or via "set 1" or "set 2" directly on Aladin: Range Default • • • • 5 - 100m (20 - 330ft) on/off 5-195min, on/off 1-5min 40m (130ft),off 60min, off 3 minutes 45 46 46 1.2-1.6bar no reset / 1 - 48hrs on/off metric/imperial on (salt water)/off (fresh water) 2-12s ; push on / push off on / off (SmartTRAK: selective) on / off on / off on / off 0 - 23h 59min, on/off ±13hrs, increments: 15min hours:minutes 24 (off) / AM/PM (on) 1.

2 Operation II 2.4 Switching on the display • automatically, on submerging in water* or when adaptation to atmospheric pressure is necessary; • manually, by pushing or . If switched on with all segments light up for 5 seconds. CNS O % Afterwards the display shows the time of the day, the O2 mix and the temperature. This display is called time of day display. Most navigation descriptions start from this display. At the surface Aladin returns automatically to this display.
2 Operation 2.5 How to navigate Aladin at the surface Starting from the time of day display you can enter into different menus. Off • (Desat. time CNS O2% • Date ) ->14 ->15 ->15 • Battery condition Time of day display Gas 1 O % ->20 MB Level L0-L ->32 Gas d O % ->37 • Enter with Gauge mode on / off ->30 Altitude ->29 (adjustment ->45) Set Set 1 ->48 ->45 / • Alarm clock • After 3 minutes without operation Aladin returns to the time of day display.
II 2 Operation 2.8 Displaying the date Date The display switches back to the time of day display after 5 seconds without operation. 2.9 Checking the battery condition From the time of day display you can check the battery condition by pushing 2x or 3 x (depending on whether there is desaturation time left). NO Aladin displays the estimated remaining battery performance for 5 seconds as a bar graph.
2 Operation / 3 SOS mode Keeping the backlight permanently on represents a severe strain on the battery. In warm waters (20 °C/68 °F and above), a new battery can sustain 20-40 1-hour dives with the backlight always on. In cold waters (4 °C/40 °F and below) the low battery warning may come on within the first dive. For temperatures between 4 °C/40 °F and 20 °C/68 °F the life of a new battery will be somewhere between 1 and 20 1-hour dives.
III Diving with Aladin III The information on the display of Aladin varies depending on the kind of dive and the dive phase. For information about diving with microbubble (MB) levels see chapter V ->32. Specific features of "Diving with two gas mixtures", are described in chapter VI ->37. 1.1 General terminology / Display during no-stop phase Current depth In metres (feet) DIVE TIME Nitrogen loading bar NO STOP CNS O2% Dive phase during which surfacing is allowed without stop.
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 max depth.
2 Attention messages and alarms III • The audible attention messages can be switched off in "set 1" ->47 or SmartTRAK. With SmartTRAK they can be switched off selectively. • In addition, the sound can be turned off completely in "set 2" ->50. WARNING If you turn off the sound you will have no audible warnings. Without audible warnings you could inadvertently get into potentially hazardous situations which could result in death or serious injury.
3 Preparation for the dive You have to check the settings of Aladin especially before the first dive. All settings can be checked and changed directly at Aladin or via SmartTRAK. 3.1 Setting the gas mixture and ppO2 max WARNING Before every dive and after changing the tank, make sure that the settings for the gas mixture correspond with the current mixture used. An incorrect setting causes Aladin to miscalculate this particular dive.
3 Preparation for the dive 3.3 III Setting the MB level See chapter V, ->34 Preparation for diving with two gas mixtures See chapter VI, ->37 3.4 Preparation for the dive and function check Switch on Aladin by pushing and check the test display: Are all elements of the display activated? Do not use Aladin if the display does not show all elements. When switching on Aladin with , the test display will not appear.
4 Functions during the dive 4.1 Immersion If the water contacts are deactivated (->47), switch on Aladin before immersion. If you have chosen the option "Water contacts off" ("set 1" or SmartTRAK), WARNING Aladin will turn on with a delay of up to 1 minute into the dive. This will affect functioning of the computer. Make sure that the computer is on before starting the dive. After immersion, starting at a depth of about 0.8m (3ft), all diving functions are monitored, i.e.
III 4 Functions during the dive 4.5 Max depth / Temperature Max depth is only displayed if it exceeds the current depth by more than 1m (3ft) (maximum indicator function). If max depth is not displayed, Aladin shows the temperature.
4 Functions during the dive 4.6 Ascent rate DEPTH Optimal ascent rate varies depending on depth between 7 and 20m/min (23 and 67ft/min). It is displayed as a percent of the reference variable ascent rate. If the ascent rate is greater than 100% of the set value, the black arrow "SLOW" appears. If the ascent rate exceeds 140%, the arrow starts flashing. Aladin provides an audible alarm if the ascent rate is 110% or greater.
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 (default 1.4bar) determines 4s the Maximum Operating Depth (MOD). Diving deeper than the MOD will expose the diver to oxygen partial pressures higher than the set maximum level. The ppO2 max and consequently the MOD can be reduced manually (->20, setting the gas mixture, point 5).
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. 1-3 segments (green area): you are safely within the no-stop range 4-5 segments (yellow area): you are approaching decompression.
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 and an audible alarm goes off. Due to the formation of microbubbles, decompression can increase massively if a decompression stop is ignored.
5 Functions at the surface 5.2 Residual nitrogen bar graph The segments in the residual nitrogen bar graph will gradually turn off as Aladin follows the offgassing of your tissues during your surface interval. There is a 1:1 equivalence in the meaning of the segments between diving and surface. Thus, on a repetitive dive the bar will resume from its status on the surface just prior to the dive.
The altitude adjustment ->45 does not affect altitude ranges nor any calculations. 6.2 Altitude ranges Aladin 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 new altitude range (1-4) and the desaturation time. Desaturation time indicated at this moment refers to adaptation time at this altitude.
IV Gauge mode In gauge mode ALL audible and visual alarms and attention messages are turned off. WARNING In gauge mode Aladin will display depth, dive time and max depth. By pressing you can scroll from the max depth to the temperature, to the average depth, to the time of day and back to the max depth. By pressing you can restart the stopwatch. This generates a bookmark. Gauge mode does not support the calculation of no-stop time or the supervision of decompression.
IV IV Gauge mode Stopwatch icon DEPTH DIVE TIME In gauge mode, after immersion, Aladin will automatically monitor the dive time and at the same time activate the stopwatch. The stopwatch will run for a maximum of 24 hours. Resets time and starts stopwatch from zero. Each start (restart) of the stopwatch creates a bookmark. Timing Hours Minutes Seconds After diving in gauge mode Aladin shows the remaining time span during which it cannot be used in computer mode.
V Diving with microbubble (MB) levels The following chapter deals with the characteristics of diving with microbubble (MB) levels. For general information about displays and features of diving with Aladin see chapter III. Microbubbles are tiny bubbles that can build up inside a diver's body during any dive and normally dissipate naturally during an ascent and on the surface after a dive.
V V Diving with microbubble (MB) levels 2 Terminology English This chapter will exclusively deal with terminology and display features used while diving with MB levels. All other features are described in chapter III (->17). 2.1 Display during MB no-stop phase MB no-stop time Remaining time at a respective depth allowing ascent without level stop.
3 Preparation for a dive with MB levels 3.1 Setting the MB level To change the MB level Aladin must be in user mode (time of day display). or 1. 2. 3. 4. until Push or until the symbol for MB levels appears. Confirm that you wish to change the displayed MB level by pushing Change MB level by pushing or . . Confirm the selected MB level with . Without confirmation the display will disappear after 3 minutes and your entries will not be accepted.
4s DEPTH DIVE TIME WARNING STOP CNS O2% Level stop ignored MB level reduced WARNING 4s DEPTH DIVE TIME STOP CNS O2% V The attention message "Level stop ignored" is activated if the requested level stop is not observed. An attention beep* goes off and the arrow STOP , the depth and duration of the ignored level stop begin flashing.
4 Functions during the dive with MB levels 4.4 Level stop and deco stop When the level stop depth equals the depth of the first obligatory decompression stop and if you are within 1.5m /5ft of the stop depth itself, Aladin shows and STOP (level stop). The indicated duration refers to level stop duration. DECO STOP Since level stops are more restrictive than decompression stops, when all decompression obligations STOP to STOP only.
VI VI Diving with two gas mixtures Depth Aladin enables you to use two different Nitrox mixtures during the same dive. Tank 1 contains the bottom mix (gas 1) and tank D contains the deco mix (gas D). Time Switching depth (MOD gas D) 1 D Bottom mix (gas 1) Deco mix (gas D) Diving with 2 gas mixtures Switching the deco gas option on and off In order to enable two-gas diving you must turn on the deco gas option in the SET 1 menu ->46.
VI Diving with two gas mixtures • The time to reset the O2% mix to air can be set with SmartTRAK between 1 hour and 48 hours or to "no reset" (default). After the reset, the oxygen fraction of gas 1 is set to 21% and gas D is set to "– – O2%" (single gas dive). Switching between single-gas and two-gas diving If gas D is not going to be used during the next dive you can either set it to "– – O2%" (->37, point 2) or you can turn off the deco gas option in SET 1.

Switch to the regulator with gas D and start breathing. Switch to gas D MOD gas d within 30 seconds. "GAS d" and the 2.
Aladin has a dive planner which allows the planning of no-stop dives and decompression dives. Basis of the planning: • selected fraction of oxygen and MOD • selected water type • selected MB level • water temperature of the most recent dive • altitude range (if any) • status of saturation at the time the dive planner is selected • assuming a normal workload of the diver and observance of the prescribed ascent rates • assumption: the change to gas D is performed at the selected MOD of gas D.
