On page 5 you will find an operating schematic.
2.1 Operating elements Contacts
TEC has 4 operating contacts B, E, +, on the outside of the housing. For manual operation, touch base contact B and any one of the other three contacts above the display with moistened fingers (bridging contacts). Contact B: Base contact, which has to be touched for all operations. Contact E: Enter contact. It serves to switch on TEC and to confirm or enter the displayed value. It is therefore comparable to the ENTER or RETURN key of a keyboard. + / Contacts: These allow to navigate between menus and, once inside a menu, to increase or decrease the indicated value.

The following data may be recalled with SmartTRAK: Number of past dives Total duration of past dives Atmospheric pressure Pairing information from up to 3 transmitters Dive profile Logbook Temperature curve Workload curve Alarms and attention messages Bookmarks
2.3 Switching on the display automatically, on submerging in water or when adaptation to atmospheric pressure is necessary; manually, by bridging contacts on housing (B-E). When TEC is in state of rest no information is displayed but the atmospheric pressure is continuously monitored. If a higher altitude range is detected, TEC switches on for 3 minutes automatically. -> 25 TEC switches on by bridging the contacts B and E. All segments light up for 5 seconds. Afterwards the display shows the selected O2 mix, the temperature and in certain circumstances an altitude range ->25. If the appertaining transmitter is switched on and located within transmitting distance, the tank pressure is displayed, otherwise <---> will be displayed. If no transmitter has been paired yet, the display will be blank. If there is a remaining saturation due to the last dive or change of altitude, TEC also displays the remaining desaturation time, the oxygen toxicity and the "no-fly time" ->24.

2.4 Checking the battery capacity After switching on TEC you can check the battery capacity by bridging the contacts B and E. The remaining capacity is displayed for 3 seconds as a percentage. If the value reaches 0%, the battery warning gets activated (->17) and the battery has to be replaced by an authorised SCUBAPRO UWATEC dealer. For a 7-day diving vacation TEC uses between % of its battery capacity. Battery capacity
2.5 Selection and activation of user functions At the surface you can select the dive planner, the logbook and gauge mode as well as the functions to enter the O2% mix and the microbubble levels by bridging the contacts + and B or and B. Gauge mode ->26 Input microbubble level ->30 Input O2 mix ->18 Logbook ->39 Dive planner ->37 After the selection of the desired function you can activate and deactivate it by bridging the contacts B and E.

2 Operation / 3 SOS mode

2.6 Active backlight
The display of TEC can be illuminated both on the surface and underwater. The backlight can be activated by pushing and holding button for 1 second. The light will turn off automatically after 8 seconds or after the time selected via SmartTRAK. The backlight can only be activated if the computer display is on.
The active backlight is no substitute for a dive torch. When diving at night or at increased depth we recommend the use of a dive torch.
2.7 Switching off the display On the surface TEC switches off automatically after 3 minutes without operation.

3 SOS mode

Time remaining until SOS mode switches off automatically
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. The display shows the "SOS" sign and the remaining length of the SOS mode. The dive will be entered in the logbook with "SOS". Other than that the SOS mode has no further impact on the displays and functions on the surface. Serious injury or death may result if a diver does not seek immediate treatment should any signs or symptoms of decompression sickness occur after a dive. Do not dive to treat symptoms of decompression sickness! Diving in SOS mode is extremely dangerous and you must assume full responsibility for such behaviour. UWATEC will assume no liability.
Once in the SOS mode, the computer will lock up and will be inoperable as a diving instrument for 24 hours. A diving accident can be analyzed at any time in the logbook and downloaded to a PC by means of the infrared interface (IrDA) and the SmartTRAK software.
4 Setting up Smart TEC (transmitter and dive computer)

For dives with a single gas mixture, assign the gas mixture to tank symbol 1 and shut off gas mixtures 2 and D. ->34 If more than one gas mixture has been selected, TEC will display at the surface and the number of gas mixtures. For dives with several gas mixtures please read pages 32 and 13 for further reference. To set the gas mixture, TEC must be in user mode. 1. Press to choose the tank for the O2 mixture you are going to enter. The tank symbol will start flashing. Press and hold to confirm your selection. 2. Bridge contacts B and + or B and until the symbol for the setting of the O2 mixture appears. 3. Confirm that you wish to change the displayed oxygen fraction by bridging B and E. 4. Change the oxygen fraction in increments of 1% by bridging B and + or B and. TEC will display the current fraction of oxygen, the maximum partial + pressure limit, ppO2 max (as pre-set by means of SmartTRAK) and the MOD. 5. Confirm the selected percentage with B and E. % 6. By bridging B and + or B and you can change the MOD for the chosen fraction of oxygen. TEC will now display the corresponding partial pressure limit (ppO2 + O2% mix max) for the new MOD. PpO2max. 7. Confirm your MOD settings with B and E. Max. Operating % ppO2max. Depth MOD Without confirmation the display will disappear after 3 minutes and your entries will not be accepted. Please refer to page 32 for the setting of gas mixtures for tanks 2 and D. The time to reset the O2 % mix to air can be set with SmartTRAK between 1 and 48 hours or to "no reset" (default). 3.2 3.3 Setting the MB level See chapter V, ->28 Preparation for diving with more than one gas mixture See chapter VI, ->32
3.4 Preparation for the dive and function check The following descriptions of the preparation are based on the assumption that all transmitters have been correctly mounted at the HP outlet of the regulators (->12) and successfully paired with TEC (->13). 1. Mount the regulator together with the transmitter on the tank 2. If present, check the reserve valve of your tank, the reserve valve must be open. 3. Switch on TEC (B-E) and check the test display: Are all elements of the display activated? Do not use TEC if the display does not show all elements. 4. Open the valve (transmitter will switch on automatically) and check the tank pressure (after approx. 10 seconds). If the pressure is insufficient, change the tank. 5. Check the connections and instruments for leaks. Never dive with leaky equipment! Repeat 4 and 5 with all transmitters you are going to use.

The prescribed ascent rate must be observed at all times! Exceeding the prescribed ascent rate can lead to microbubbles in the arterial circulation which can lead to serious injury or death due to decompression sickness. In case of an improper ascent TEC may require a decompression stop even within the no-stop phase because of the danger of microbubble formation. The decompression duration necessary for the prevention of microbubbles can increase massively if the ascent rate is exceeded. From great depth a slow ascent may cause heightened saturation of tissues and an extension of both decompression duration and total ascent time. At shallow depth, a slow ascent may shorten the decompression duration. Display of the ascent rate has the priority over <CNS O2>.

Visual alarm

Audible alarm

Excessive ascent rates for longer periods are entered in the logbook.
4.7 Partial pressure of oxygen (ppO2 max) / Maximum Operating Depth (MOD) The maximum partial pressure of oxygen ppO2 max (default 1.4 bar) determines 4 sec 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 MOD and consequently the ppO2 max can be reduced manually at TEC (->18, setting the gas mixture, point 6). In addition the maximum allowed ppO2 can be set by means of SmartTRAK between 1.0 to 1.95 bar. %
The MOD is a function of ppO2 max and the mixture used. If during the dive the MOD is reached or exceeded TEC sends an audible attention message, the ascent arrow appears and the current depth display starts flashing. Ascend to a shallower depth in order to diminish the danger of oxygen poisoning. Change to the gas mixture that is required at this depth by selecting the appropriate tank symbol.
The MOD should not be exceeded. Disregarding the warning can lead to oxygen poisoning. ppO2 max should not be set higher than 1.6 bar.
city reaches 75%. The symbol <CNS O2> flashes and the ascent arrow appears. Ascend to shallower depth to decrease oxygen loading. When oxygen toxicity reaches 100%, an audible alarm goes off every 4 seconds. <CNS O2>, the precentage value and the ascent arrow flash. Danger of oxygen toxicity! Start ascent at once.
During an ascent and if the CNS O2 % value does not increase anymore (due to a lower partial pressure of oxygen), the audible warning is suppressed. During the ascent, the display of the oxygen toxicity is replaced by the ascent rate. If the ascent is stopped, the display changes back to the indication of the CNS value. TEC will display CNS O2 % values exceeding 199 % with 199 %. The tank pressure is also used for the calculation of the remaining bottom time (RBT) and the workload.

Ignored decompression alarm

Total time of ascent

On all dives with TEC, make a safety stop for at least three minutes at a depth of 5 m (15 feet).
4.12 Safety stop timer The safety stop timer displays the time span a diver should spend at the safety stop depth at the end of the dive. The timer is activated by the diver and counts back to zero, starting with the time that was pre-set with SmartTRAK. It can be restarted any number of times. Range: 1 - 5 minutes (default 3 min.)
The safety stop timer can be activated under the following conditions: Depth < 6.5 m (21 ft), no-stop display 199 min., gauge mode is switched off. Activate the safety stop timer by pressing. The timer begins to count backwards and a bookmark will be created in the dive profile. The safety stop timer will switch off automatically if the depth exceeds 6.5 m (21 ft) or the no-stop phase is shorter than 199 minutes.

5 Functions at the surface
5.1 End of a dive After reaching the surface (<0.8 m/3 ft) TEC remains in dive mode for 5 minutes. The delay allows for surfacing for a short period for orientation. After 5 minutes the dive is closed and it is entered into the logbook.
For the calculations of the desaturation and no-fly time it is assumed that the diver breathes air while on the surface.

5.2 Desaturation time

Oxygen toxicity Desaturation time 5.3 No-fly time No-fly time Do not fly icon
DESAT , desaturation time in hours and After the dive has been closed minutes and, if available, oxygen toxicity is displayed. Desaturation time is determined either by oxygen toxicity, nitrogen saturation or the regression of microbubbles, depending on which requires the longer time. Oxygen toxicity (<CNS O2>) is displayed and adjusted until the value becomes 0%. Desaturation time is 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. The calculations are nevertheless continued in the background.
The <no-fly time> is indicated beside the icon <do not fly>. <No-fly time> is the time in hours that should pass before a flight and is displayed and adjusted until the value becomes 0 hours.
Flying while TEC displays <do not fly> may lead to serious injury or death from decompression sickness.
5.4 Microbubble warning Through repetitive dives microbubbles accumulate in the lungs if the surface interval is not long enough. Ignoring decompression stops or ascending at an excessive rate can also lead to microbubbles in tissues. In order to reduce the risk of decompression sickness for repetitive dives, the surface interval should be planned long enough. If TEC calculates that the formation of microbubbles occurs during the surface interval, it will advise a diver to extend the surface interval via the microbubble warning.

3 Preparation for a dive with microbubble levels (MB levels)
3.1 Setting the MB level To change the MB level TEC must be in user mode. 1. Bridge contacts B and + or B and until the symbol for MB levels appears. 2. Confirm that you wish to change the displayed MB level by bridging B and E. 3. Change MB level by bridging contacts B and + or B and . 4. Confirm with B and E the selected MB level. Without confirmation the display will disappear after 3 minutes and your entries will not be accepted. TEC will display the symbol to confirm that an MB level beyond L0 (L1-L5) has been chosen. During the dive the MB level is shown by pressing briefly. If however a level stop is ignored, the new MB level is permanently shown (->31). MB levels have an influence on the dive planner.
4 Functions during the dive with microbubble levels
4.1 Level stop information Microbubble (MB) no-stop time While diving with MB levels L1 to L5 TEC will display the MB no-stop time instead of the ordinary no-stop time. Within the MB no-stop time no level stops are required. The arrow NO STOP and the MB level symbol are visible. The remaining MB no-stop time is shown in minutes. Information and alarms for MB no-stop time and ordinary nostop time are the same (->22). Regardless of the MB level, we generally recommend to perform a slow ascent during the last few metres / feet.
MB no-stop time Level stop Level stop icon
On entering the level stop phase, the arrow NO STOP disappears and the arrow LEVELSTOP appears. The LEVELSTOP arrow flashes for 8 seconds and an audible attention beep goes off. To complete the dive without being reduced to a lower MB level, all requested level stops must be observed. To the right of the LEVELSTOP arrow, the deepest level stop is displayed in metres/feet. The display <3m 2:> (<10ft 2:>) means that a level stop of 2 minutes at a depth of 3 metres (10ft) has to be observed. When a level stop obligation is finished, the next higher level stop if present is displayed. When all level stops have been observed, the arrow LEVELSTOP extinguishes and the arrow NO STOP reappears. The indication of time shows the MB no-stop time again.

Deepest level stop depth Level stop duration Total ascent time
The attention message "Level stop ignored" is activated if the requested level stop is not observed. An attention beep* goes off, the arrow LEVELSTOP , the depth and duration of the ignored level stop begin flashing. To complete the dive without being reduced to a lower MB level, you must descend to the prescribed depth immediately! The warning "microbubble level reduced" is activated if the diver ascends more than 1.5m (5ft) above the required level stop. TEC reduces the microbubble level, an attention beep* goes off and for the rest of the dive the new MB level is indicated in the position of the maximum depth. The level stop for the reduced MB level is now displayed. To complete the dive without being further reduced to an even lower MB level the new level stop must be observed.
Level stop ignored Microbubble level reduced 4 sec

* Attention beeps can be suppressed via SmartTRAK.
4.2 Total time of ascent TEC displays the level stop information and the total time of ascent. This includes the time of ascent as well as all level stops.
Total ascent time 4.3 Decompression obligation Decompression obligation
The total 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 if TEC detects a higher workload.
Avoid decompression dives when diving with MB levels.
Level stop information 4 sec
TEC calculates and displays level stops to reduce microbubble formation, but it also calculates the diver's decompression data. If decompression stops become obligatory, the DECO symbol will be displayed. The total ascent time will now also contain a decompression stop.
You are close to entering decompression: At the beginning of a decompression phase an attention beep goes off and the DECO symbol flashes for 8 seconds. In order to prevent a dive with long decompression stops it is recommended that you ascend a few metres/feet on seeing this message.

7. Above MOD for 100%, missed switch: now TEC-3 gives the same decompression prognosis as TEC1. TEC-4 gives the same decompression prognosis as TEC-2. 8. Again below the MOD for 100%: TEC-3 and TEC-4 again show credit for the presence of the 100% mix in their calculations 9. Above MOD for 100%, switch carried out: TEC-3 and TEC-4 show the tank pressure in the 100% tank. The RBT agrees. TEC-2 is not receiving anymore signals from the 50% tank and shows - - -. However, the slow ascent and delayed switch to 100% has caused the decompression prognosis to be shorter on TEC-2 than TEC-3.

VII Dive planner

TEC has a dive planner which allows the planning of no-stop dives as well as decompression dives with freely determinable surface intervals and with up to three different gas mixtures. Basis of the planning: selected fraction of oxygen and MOD of all active gas mixtures selected microbubble 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: changes of gas mixture are performed at the selected MOD of mixtures 2 and D. If two or more divers using computers are planning a dive, planning for all divers has to be based on the dive computer showing the shortest no-stop times. Failure to do this may lead to serious injury or death from decompression sickness.
Before using the dive planner, the fraction of oxygen must be entered for each required tank and the depths for a change of gas mixture for tanks 2 and D must be entered. Tanks, i.e. gas mixtures which are not going to be used during the next dive must be switched off (->33-34). All 'activated' gas mixtures will be indicated by their tank symbols and allowed for calculation.
1 Planning a no-stop dive
With the contacts B and or B and + you can select the dive planner at the surface. (The dive planner cannot be selected in gauge mode) The microbubble warning and its duration are displayed if Microbubble warning TEC detects an increased risk (Do Not Dive) due to the accumulation of microbubbles. Duration of the warning
Dive planner icon Enter the dive planner if rep. dive
Enter the dive planner with B and E. The input window for the time interval is displayed if there was a remaining desaturation (DESAT) before the Dive Planner has been selected. This surface interval between now and the beginning of the dive can be changed with the contacts + and in steps of 15 minutes.
Input of the surface interval Icon for microbubble level 1-5
If a microbubble warning (no dive) and its duration has been displayed, TEC proposes this time rounded up to the next 15 minutes as surface interval. If the proposed interval is shortened, the microbubble warning appears.

With B and E you confirm the displayed interval (if applicable), then TEC starts scrolling the no-stop times. The no-stop times are displayed in 3 metre increments (10 ft) and are displayed for every increment for about 2 seconds. The process starts at 3 metres (10 ft). If a microbubble level has been selected (L1-5), the MB no-stop time is shown. No-stop times will be displayed as long as the selected maximum operating depth (MOD) of tank 1 is not exceeded. On page 24 you will find further information and safety considerations regarding the microbubble warning.

VII Dive planner 2 Planning a decompression dive
1. Activate the dive planner for a no-stop dive ->37. 2. Wait until the desired depth appears, then switch into decompression planning by bridging contacts B and E. TEC shows the bottom time (no-stop time + 1 minute) and the appropriate decompression information or level stop data respectively. 3. <Add> asks that you set the bottom time. This is done with contacts B and +, B and respectively. As soon as the contacts are no longer bridged, TEC calculates the decompression information or level stop data respectively for this set bottom time. If you wish to plan a decompression dive at another depth, switch from decompression planning to no-stop planning by means of B and E. TEC again shows the scrolling no-stop times. Now you can switch between no-stop planning and decompression planning at will with contacts B and E. If the calculated decompression information and the total ascent time exceed 199 minutes, or the CNS O2 % value exceeds 199%, the said values will start flashing on the display or < > values appear and the decompression calculation is suspended until the bottom time has been reduced accordingly. CNS O2% values higher than 199% will be displayed as 199 %.

Bottom Time +

3 Leaving the dive planner
With the contacts B and E (1-2 sec) you can exit the Dive Planner. This also occurs after three minutes without operation.

VIII Logbook

1 Survey A dive is entered in the logbook if the dive time is longer than 2 minutes. TEC records the profiles of about 100 hours of diving. This information can be transferred to a PC with the standard infrared interface (IrDA) and the Windows software SmartTRAK. Up to 99 dives can be displayed directly on the dive computer. The following information of the dive is displayed:

Logbook icon Ignored decompression stop* or diving in SOS mode Too fast ascent* Altitude range (if any) Maximum depth / Lowest temp. / MB level (at the beginning of the dive) Fraction of oxygen tank 1 " tank 2 " tank D *Alarms during the dive
Diving in gauge mode MB level reduced* Dive time Dive number CNS value at the end of the dive Duration of surface interval (only with repetitive dives) Increased workload warning*
dP = differential pressure (gas consumed) Gas consumed (bar or psi) from tank 1 (displays only those gas " tank 2 mixtures used during the dive) " tank D Ignored decompression stop*
If a dive is started within adaptation time (after a change of altitude), the adaptation time is displayed instead of the surface interval.
2 Operation With the contacts B and + or B and you can select the logbook. With B and E you enter the logbook.
If there was a remaining desaturation time (DESAT) before selecting the logbook, the time since the last dive (surface interval) is displayed.
With B and E you get the most recent dive displayed (LOG 1). Each bridging of B and + or B and causes a jump to the next older or more recent dive. Upon continuous bridging of the contacts all dives are displayed successively.
With the contacts B and E you can exit the logbook. The logbook closes automatically after 3 minutes without operation.

2 Maintenance

The tank pressure gauge and the parts of this product used to measure the tank pressure should be serviced by an authorized SCUBAPRO UWATEC dealer every second year or after 200 dives (whichever comes first). Aside from that your TEC is virtually maintenance free. 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 TEC, the following recommendations will help assure that it will give you years of trouble free service:

Avoid dropping or jarring your TEC. Do not allow your TEC to be exposed to direct, intense sunlight. Rinse your TEC thoroughly with fresh water after each dive. Do not store your TEC in a sealed container; make sure there is free ventilation. If there are problems with operating the contacts, use soapy water to clean TEC and dry it thoroughly. The surface of your TEC housing can be treated with silicone grease. Do not apply grease to the water contacts! Do not clean TEC with liquids containing solvent (apart from water). If the service icon appears, TEC must not be used for any further dives. Take your dive computer to an authorized SCUBAPRO UWATEC dealer. Take the dive computer to an authorised SCUBAPRO UWATEC dealer in order to change the batteries. The battery replacement is carried out by a SCUBAPRO UWATEC subsidiary. TEC is checked for its technical integrity at the same time. Do not attempt to have the batteries changed by anyone other than an authorised SCUBAPRO UWATEC dealer.
2.1 Replacing the battery of the transmitter
It is recommended to have the battery of the transmitter replaced by an authorized SCUBAPRO UWATEC dealer. The change must be made with particular care in order to prevent water from seeping in. The warranty does not cover damages due to an improper replacement of the battery.

I UWATEC Aladin dive computers
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. You MUST be familiar with all signs and symptoms of decompression sickness before using Aladin PRIME and Aladin TEC! Seek IMMEDIATE treatment for decompression sickness should any of these signs or symptoms occur after a dive! There is a direct correlation between the effectiveness of treatment and the delay between the onset of symptoms and the treatment for decompression sickness. Only dive with Nitrox after you have been thoroughly instructed by a recognised institution. Repetitive dives Do not start your next dive before your CNS O2% status has dropped below 40%. Diving with Nitrox: Make sure your surface interval is long enough (just like diving with compressed air). Plan for a minimum surface interval of two hours. Oxygen, too, needs sufficient time to leave the body. Match gas mixture to the intended dive. Do not attempt a repetitive dive if the microbubble warning is visible on the display. Plan a day without diving once a week. If you have to change computers, wait at least 48 hours before carrying out your next dive. Diving after a reset of the remaining saturation (reset, see page 41, or battery replacement, see page 45) may lead you into potentially hazardous situations which could result in death or serious injury. After a reset of the remaining saturation do not dive for at least 48 hours.
Altitude and diving Do not dive at altitudes higher than 4000m (13000 feet). After a dive do not rise to altitudes that Aladin PRIME or Aladin TEC prohibit via the flashing altitude range number (see page 27). Flying after diving After diving, wait at least 24 hours prior to flying.
Aladin PRIME and Aladin TEC dive instruments are a personal protective equipment in compliance with the essential safety requirements of the European Union directive 89/686/EEC. RINA SpA, Via Corsica 12, I-16128 Genoa, notified body no. 0474, have certified the conformity with the European Standard EN 13319:2000.

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. Aladin includes this in the calculations and displays the necessary information: <O2% MIX> Fraction of oxygen: The fraction of oxygen in the Nitrox mixture can be set between 21% (normal compressed air) and 50% (TEC:100%) in 1% increments. Your selected mix will be the basis for all calculations. Maximum allowed partial pressure of oxygen: the higher the fraction of oxygen in the mixture, the shallower the dive depth at which this value of the partial pressure of oxygen is reached. The depth at which ppO2 max. is reached is called Maximum Operating Depth (MOD). When you enter the settings for the gas mixture, Aladin will display the ppO2 max. limit setting and the corresponding MOD. Aladin warns the diver audibly and visually once the depth is reached at which the ppO2 reaches the maximum allowed value ->23. Default setting of ppO2 max. is 1.4 bar. TEC The value of ppO2 max. can be set by means of SmartTRAK or with "set 1" between 1.2 and 1.6 bar (->40). It can also be reduced at the time of setting the gas mixture (->18). The CNS O2% value/alarm is not influenced by the selected ppO2max. setting. <CNS O2> Oxygen toxicity: With the increased percentage of oxygen, the oxygen in the tissues (especially in the central nervous system (CNS)) becomes important. If the partial pressure of oxygen rises above 0.5 bar, the CNS O2 value increases, if the partial pressure of oxygen is below 0.5 bar, the CNS O2 value decreases. The closer the CNS O2 value is to 100%, the closer the limit where symptoms can occur ->23.

4.10 Decompression information NO STOP and the no-stop time (minutes) are displayed if no decompression stops are necessary.
No-stop display <99:> means remaining time of 99 minutes or more. No-stop time is calculated on line and influenced by the current water temperature If no-stop time drops below 3 minutes, an audible attention signal is activated, the no-stop value and the nitrogen loading bar begin to flash. If no-stop time is less than 1 minute, the no-stop display shows the flashing value "0". In order to prevent a decompression dive, ascend slowly until the no-stop time is 5 minutes or more. Dives that require decompression stops are not recommended.
No-stop time Nitrogen loading bar 4 sec
No-stop time less than 1 minute
Decompression values Decompression obligation
On entering the decompression phase, "NO STOP" disappears, the symbol appears and an attention beep goes off. The nitrogen loading bar stops flashing and the 6th segment lights up (red area). The deepest decompression stage in metres (feet) is displayed and the decompression stop duration of the displayed stage appears in minutes. The display <7: 3m (10ft)> means that a decompression stop of 7 minutes at a depth of 3m (10ft) 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 symbol extinguishes, "NO STOP" and no-stop time reappear.
Decompression stop duration Decompression depth
Deco stop depths deeper than 27m (90 ft) are displayed as < : >
Ignored decompression alarm
The decompression alarm is activated if the , WARNING 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. When the surface is reached during the decompression alarm, the arrow , the decompression stop duration and decompression stop depth continue 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 (->14). If the total (cumulative) duration of the decompression alarm is longer than one minute, it is entered in the logbook. Descend to the prescribed decompression stop depth immediately!

Total time of ascent

As soon as decompression stops are necessary Aladin shows the total time of ascent. This includes the ascent time from the current depth to the surface and all decompression stop obligations. The total time of ascent is calculated on the basis of the prescribed ascent rate. Total time of ascent can be subject to change if the ascent rate is not ideal (100%). Ascent time greater than 99 minutes is displayed as < >.

Total ascent time

On all dives with Aladin, make a safety stop for at least three minutes at a depth of 5 m (15 feet).

4.11 Safety stop timer

The safety stop timer displays the time span a diver should spend at the safety stop depth at the end of the dive. The timer is activated by the diver and counts back from 3 minutes (default) to zero. It can be restarted any number of times. TEC The duration of the timer can be set between 1 and 5 minutes. The safety stop timer can be activated under the following conditions: Depth < 6.5 m (21 ft), no-stop display 99 min., gauge mode is switched off. Activate the safety stop timer by pressing. The timer begins to count backwards and a bookmark will be created in the dive profile. If you press again, the timer will start again from the full value. To visualize the safety stop bookmarks on the dive profile, the box "Generate safety stop markers" under "Program options" in SmartTRAK must be selected. The safety stop timer will switch off automatically if the depth exceeds 6.5 m (21 ft) or the no-stop phase is shorter than 99 minutes.
Safety stop icons Remaining Minutes time span Seconds
5 Functions at the surface

5.1 End of a dive

After reaching the surface (<0.8 m/3 ft) Aladin remains in dive mode for 5 minutes. The delay allows for surfacing for a short period for orientation. After 5 minutes the dive is closed and it is entered into the logbook. The time of day is then displayed for 3 minutes, after which the computer turns off.
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. There are two exceptions however: the uppermost segment will stay lit until the desaturation time is completely extinguished. This is done to show that there is desaturation time left and that a dive started at this point will be logged as a repetitive dive. If the remaining desaturation time is very short, this segment could however at first disappear during the dive; during the 24 hours of an SOS-lock, all segments will stay on. 5.3 Desaturation time, No-fly time and Microbubble warning 5 minutes after a dive Aladin shows the time of day, the <do not fly time>, No-fly time the microbubble warning (if applicable), the current altitude range and the proDo not fly icon hibited altitude range (->27). Microbubble No-fly time is the time in hours that should pass before a flight and is diswarning played and adjusted until the value becomes 0 hours.

Level stop phase To complete the dive without being reduced to a lower MB level all requested level stops must be observed.
3 Preparation for a dive with microbubble levels (MB levels)

Decompression stop depth = level stop depth
5 Complete a dive with MB levels
A dive with MB levels is completed the same way as a dive without MB levels (L0) (->25), save for the following exceptions: If the MB level has been reduced during the dive, Aladin TEC will display a flashing MB level symbol and the current MB level for five minutes after reaching the surface. The dive is then completed and Aladin TEC changes to user mode with the MB level switching back to the original MB setting. Repetitive dives and microbubble levels: If during a dive a level stop is being ignored and the diver starts another descent shortly afterwards, Aladin TEC might immediately request level stops. To complete the dive with the initially set MB level all level stops must be observed.

VI Dive planner

Aladin has a dive planner which allows the planning of no-stop dives. TEC The dive planner allows planning of decompression dives. Basis of the planning: selected fraction of oxygen and MOD TEC selected water type TEC selected microbubble 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 If two or more divers using computers are planning a dive, planning for all divers has to be based on the dive computer showing the shortest no-stop times. Failure to do this may lead to serious injury or death from decompression sickness.
