Safety considerations

You must carefully read and understand this entire manual before using your Aladin Sport Plus. Diving has many inherent risks. Decompression sickness is among the most serious of those 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 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 Sport Plus! The Aladin Sport Plus is a sophisticated dive computer to assist a trained and certified diver in making decisions concerning dive planning and execution. As with any tool, the Aladin Sport Plus may be misused if the following safety and operational precautions are not strictly followed. If they are followed, careful use of the Aladin Sport Plus can increase your diving enjoyment and reduce your risk of decompression sickness. If they are not, you will be placing yourself at serious risk for decompression sickness. While the Aladin Sport Plus is a technically advanced tool based on a mathematical model of decompression sickness, neither it nor any other diving computer (or table) can exactly monitor the physiological changes that occur in your body as you dive. In addition, each diver will vary in his or her susceptibility to decompression sickness. In addition, each diver will vary in his or her susceptibility to decompression sickness. In addition to this, each individual divers own susceptibility may vary from day to day. Combined with the fact that decompression modelling is an inexact science, and must be based to some extend on certain unproven assumptions, it is emphasis on you, the individual diver, to dive responsibly and to carefully follow all standard safe diving practices as well as the recommendations contained in this manual. Guidelines for the use of Aladin Sport Plus: The following guidelines for using Aladin Sport Plus are derived from the latest medical research for diving with diving computers. Following these guidelines will greatly increase your safety while diving, but cannot guarantee that decompression sickness will not occur. The Aladin Sport Plus is designed for dives made with compressed air only. Do not use the Aladin Sport Plus for dives made with nitrox or other mixed gases. Due to the danger of nitrogen narcosis do not dive deeper than 40 m. Aladin Sport Plus does not warn you in this respect.

On all dives with the Aladin Sport Plus, make a safety stop for at least one to three minutes within the 3 to 5 metre zone. Always make the deepest dive of the day first when repetitive dives are planned, and for each dive make sure that the deepest portion of that dive is done at the beginning of the dive. All divers using dive computers to plan dives and indicate or determine decompression status must use their own computer which they take with them on all dives. If the Aladin Sport Plus fails at any time during the dive, the dive must be terminated, and appropriate surfacing procedures should be initiated immediately. On any given dive, all divers in a buddy group must follow the most conservative dive computer for that particular dive. Repetitive dives after exchanging the dive computer: Wait at least 24 hour before you start with the repetitive dive. Always observe the optical alarm signals of the Aladin Sport Plus. Avoid situations of increased risk for decompression sickness which are marked with a warning sign in this operating manual. The decompression algorithm contained in the Aladin Sport Plus only serves for emergency or unintended decompression. You MUST follow the ascent rates as indicated by the Aladin Sport Plus and if the computer should fail for any reason, you must ascend at a rate of no greater than 10 metres per minute. You MUST be familiar with all signs and symptoms of decompression sickness before using the Aladin Sport Plus! 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. See also page 10-11, 40-41, 65.

1 Aladin Sport Plus - Safe No-Stop Diving / 2 Your Personal Companion 1 Aladin Sport - Safe No-Stop Diving
The proven no-stop dive computer Aladin is furnished with a new, revolutionary calculation model which makes it even safer and more comfortable. The Aladin Sport Plus is designed for no-stop diving, but also provides the necessary information for safe diving in case of a decompression dive. Aladin Sport Plus displays all information necessary for safe diving in such a manner that it is easy to survey and to be understood at once. The convincingly simple handling and the high comfort of carrying speak for themselves from the first dive. Read this operating manual carefully and to the last page.

3 The Calculation Model ZH-L8 ADT
3.1 Description The Aladin Sport Plus uses a new decompression calculation model known as the ZH-L8 ADT. This model uses eight compartments or tissue groups with nominal half time periods from 5 to 640 minutes. This model differs considerably from other models by its consideration of the following additional physiological processes: 1. Blood perfusion to the bodys organs is not constant. Skin and muscle tissues are especially subject to changes in blood perfusion, depending on temperature and work load. Changes in blood perfusion to these organs change their nitrogen saturation tolerance. The model used by the Aladin Sport Plus takes these effects into account and thus the skin and muscle compartments in the Aladin Sport Plus show variable half-time periods and saturation tolerances. Decompression information is calculated according to the workload and decrease in skin temperature. The decrease in skin temperature is based upon the water temperature and the dive time. By considering these changes in saturation, the time that must be spent at the surface prior to flying can be considerably lengthened, depending upon the depth, time, and temperature of a dive, as well as the divers work during that dive. 2. The decompression model used by the Aladin Sport Plus considers nitrogen in both its dissolved as well as its gaseous phase (microbubbles). Formation of microbubbles is considered to be a strong indicator of a high risk of decompression sickness. The Aladin Sport Plus model calculates the formation of microbubbels depending on various assumed influences in arterial and venous blood. In normal, slow ascents, microbubbles form mainly in venous blood. During fast ascents, microbubbles may also form in arterial blood and in the bodys tissues as well. If a particular dive profile may result in the creation of microbubbles according to the Aladin Sport Pluss model, decreased bottom time and/or increased decompression times as well as increased no fly time will be indicated. Microbubbles can form if the diver makes too fast an ascent, ignores required decompression stops, or makes repeated ascents during a dive (yo-yo diving). These microbubbles can form in arterial blood as well as in the bodys tissues. If these microbubbles partially impair circulation, the rate of gas diffusion and saturation tolerance for those tissues immediately surrounding this area of impaired circulation are changed. If required, no-stop time, decompression time and -depth will be adjusted in such a way that already existing microbubbles will stop growing. Increased decompression time will also assist those local areas of impaired circulation to desaturate with less risk of decompression sickness.

The calculation of microbubbles results in altered ascent instructions. If microbubbles are assumed to be present based on the data used by the Aladin Sport Plus, the ascent rate to the surface is reduced to 23 feet/minute. This will help prevent the formation of microbubbles in the arterial circulation and minimizes formation of microbubbles in the venous circulation after the dive. 3.2 Advantages On first dives with correct diving technique and avoiding risk situations, there are no extended decompression times. On the other hand, it is possible to react correctly in risk situations due to the realistic simulation of the physiological processes in the body. This increases safety considerably. Risk situations are, for example: Repetitive dives, especially those deeper than 20 metres and those with short surface intervals. Repetitive diving over the course of several successive days. Diving in cold water. Yo-yo diving (repeated descents and ascents to the surface during a given dive). Flying within 24 hours after diving. Excessive ascent rate.
In case of mistakes on the part of the diver, actual prevention of decompression sickness is possible for the first time due to the reconstruction of the bubble formation and its consequences. The correction of the decompression must not be confused with a real recompression, which serves as therapy of already existing damage.

4 Safety in Diving

If signs or symptoms of decompression sickness occur after diving with Aladin Sport Plus, seek IMMEDIATE treatment at the nearest recompression facility. With its new decompression model Aladin Sport Plus offers a so far unreached level of safety. However, responsibility for the dive finally remains with the diver as before. The usual diving caution is still absolutely necessary when diving with Aladin Sport Plus. In case of diver mistakes (ignoring decompression stops, excessive ascent rate etc.) Aladin Sport Plus can calculate a corrected ascent instruction immediately which minimizes the occurrence of decompression sickness. The prevention of barotrauma and nitrogen narcosis still lies in the hands of the diver. Aladin Sport Plus is a highly developed technical instrument of high reliability. Despite this, the user of the Aladin Sport Plus is to have an understanding of the physiological interrelations, to know the use of decompression tables and to have them with him on every dive. Should an incident occur, the detailed previous history of the incident is stored in the dive computer. The evaluation of these records allows better diagnosis and the most effective treatment for the diver.

1 The Aladin Sport Plus-System 1
The dive computer as the central unit of the Aladin Sport Plus system becomes a valuable aid by a number of additional features: 1 During the dive the Aladin Sport Plus dive computer supplies all important dive- and decompression information and warnings if necessary. It has a logbook with the last 19 dives and a dive planner. 2 The dive computer has a data memory which stores the dive data. The data can be downloaded out into a MemoMouse from where they can be transmitted to a Windows personal computer with the logbook program DataTrak. MemoMouse and DataTrak are available as an option.

2 Operation
2.1 Operating the surface functions Switching on display: automatically, on submerging in water or when adaptation to atmospheric pressure is necessary. manually by manipulating contacts on housing. Switching off display: automatically, after three minutes without operation. Aladin Sport Plus 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. Contact B: Base contact, which has to be touched for all operations. Contact E: Enter contact. It serves the switching on of the computer and the activation of logbook and diveplan-mode. It is also used to confirm inputs and is therefore comparable to the ENTER- or RETURN-key of a computer. + / contacts: They serve the selection of logbook and dive-plan as well as the setting of values (time, depth, dive-number etc.).
Active backlight The display of the Aladin Sport Plus can be illuminated both on the surface and underwater. The backlight can be switched on by pressing the unit above the display. The light will turn off automatically after 7 seconds. 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. Replace the battery if the battery warning appears. See page 38.
On page 2 of the English manual you will find a reference guide. On page 3 of the German manual you will find an openable operating scheme. 1. Aladin Sport Plus is in a state of rest; no information is displayed (-> sleep-mode or -> surface-sleepmode).

Ready-Modus 2.2 Operating modes
Surface-Modus Aladin Sport Plus works in various operating modes: Sleep-mode: Activation: automatically When Aladin Sport Plus is not used, it is in the so called sleep-mode. In that case, the electronics are sleeping in that the display does not show any information. The computer is briefly activated once every minute to measure atmospheric pressure. The display remains switched off. If a change in altitude is recognized, Aladin Sport Plus switches to -> surface-mode for 3 minutes.
Ready-mode: Activation: By touching contacts B and E from sleep-mode. To check the display, all signs light up for 5 seconds.
Aladin Sport Plus switches into ready-mode afterwards. Once in ready-mode, the display is switched on and altitude sections are eventually displayed. By touching contacts B and E in the ready-mode once more, Aladin Sport Plus will display the remaining battery capacity by percentage. Three minutes after activating the ready-mode, Aladin Sport Plus will fall back into the > sleepmode.
Dive-mode: Activation: automatically, when depth more than 0.5 m. In dive-mode all diving functions are monitored: i.e. depth and dive time are displayed, maximum depth is stored, saturation of tissues is calculated with allowance for temperature, no-stop time or decompression prognosis is determined, ascent rate is controlled and displayed and the correctness of the decompression procedure is supervised.

ft h m

Wait-mode: Activation: automatically on reaching the surface. The wait-mode is activated if the the diver surfaces (diving depth less than 0.5 m). At the surface, the dive is not completed and entered into the logbook for an interval of 5 minutes. This allows a short surfacing for the purpose of orientation.

max. depth depth

deco info dive time
Surface-mode: Activation: automatically after a dive or when changing altitude. After a dive has been completed, Aladin Sport Plus is in surface-mode. All data belonging to the surface interval are calculated and displayed: simulation of microbubble formation, actualization of the saturation of tissues depending on the calculated skin temperature and the assumed work load at the surface, calculation of desaturation time and no fly interval. In order to save energy, Aladin Sport Plus falls into the surface-sleep after 3 minutes. The functions of surface-mode are then carried out in the background. The atmospheric pressure is measured in surface-sleep once every minute. If the atmospheric pressure decreases, for example in case of change of altitude, Aladin Sport Plus switches from sleep-mode or from surface-sleep into surfacemode automatically and displays the adaptation time. The adaptation time is the time after which all body tissues have adapted to the ambient pressure (= desaturation time).
Logbook-mode: Activation: manually by contacts Data of 19 past dives can be called up in the logbook-mode. It shows maximum depth, dive time, preceding interval*, altitude sections and, where appropriate, alarms. A dive is entered in the logbook if it has lasted more than 2 minutes. When the dive was a repetitive dive then it also shows the interval which has passed since the last dive or a preceding change of altitude. The last 37 dives and the last 200 minutes of dive-profiles can be downloaded out into a MemoMouse and later from there into a personal computer (Windows). * Preceding interval is only shown when the computer calculated that there was a residual nitrogen uptake at the beginning of the logged dive.
Diveplan-mode: Activation: manually by contacts The diveplan-mode serves the planning of a future dive. It allows the planning of no-stop dives at various depths. On repetitive dives, the surface interval can be chosen at will. Calculations are based on the temperature data of the last dive and assuming normal workload.
SOS-mode: Activation: automatically If the diver remains above a depth of 0.5 metres for more than three minutes without observing the prescribed decompression, the computer switches into SOS-mode after the dive and displays <SOS> instead of the depth. The computer is locked from use for the next 24 hours. Desaturation is further calculated including microbubbles in the tissues. Diving is again possible after 24 hours, but the SOS-mode can influence the calculations of Aladin Sport Plus for three days after the incident due to the possible presence of microbubbles. If a diver using Aladin Sport Plus experiences a diving accident resulting in decompression sickness, the dive can be analyzed by means of the MemoMouse and DataTrak-software. An automatic program transmits the logbook data after connecting the dive computer via MemoMouse with a PC once a minute from the locked dive computer to the personal computer. Dive computer, MemoMouse and PC need to be connected. The PC has to be ready for receiving data and the DataTrak download-procedure has to be activated. Serious injury or death may result if a diver does not seek immediate treatment at a recompression chamber should any signs or symptoms of decompression sickness occur after a dive.

1 Terminology/Symbols

The Aladin Sport Plus is a dive computer primarily designed for diving in the no-stop phase. If a decompression dive is carried out in spite of that, the Aladin Sport Plus offers a decompression prescription. The indications of the display vary depending on the phase of the dive. No-stop phase: Dive phase during which ascent is allowed without decompression stops. Decompression diving should not be attempted by recreational or sport scuba divers. Do not use the Aladin Sport Plus for intentional decompression diving. Decompression phase: Decompression depth: Dive time: Dive phase during which a decompression stop has to be observed during the ascent. Lowest stage is displayed. Time of the dive below depth of 1.2 m.

2 Attention Messages and Alarms
Aladin Sport Plus draws the divers attention to certain situations and warns the diver of unsafe diving practices. Attention messages and alarms are communicated to the diver optically by lit up symbols, letters or flashing figures. 2.1 Attention messages Attention messages come up in the following situations: Dive in mountain lake depth dive time On a change of altitude, the altitude section (0-3) and adaptation time is shown. See pages 37-38.

On entering the decompression phase, the arrow <NO STOP> extinguishes. The arrow <STOP> appears. Right below the arrow, the lowest decompression stage in metres is displayed. The display <6m> means that a decompression stop at a depth of 6 m has to be made. When a decompression stop has been finished, the next higher is displayed. When all decompression stops have been made, the arrow <STOP> extinguishes and the arrow <NO STOP> reappears. The indication of time on the lower right shows the no-stop time again.
4 Functions during the Dive / 5 Functions at the surface

Messages:

Descend to the prescribed decompression depth immediately!
5 Functions at the surface

5.1 End of a dive

After reaching the surface, Aladin Sport Plus switches into wait-mode automatically for five minutes. This is the time span necessary to recognize the end of the dive. The delay allows the diver to come to the surface for orientation and to resume the dive afterwards. When the dive is closed after 5 minutes in wait-mode, it is entered into the logbook and Aladin Sport Plus switches into surface-mode. In surface-mode, Aladin Sport Plus shows desaturation time and no fly time.
The decompression alarm is activated if the decompression stop is ignored. Arrow <STOP> flashes. Due to the formation of microbubbles decompression can increase massively while a decompression stop is ignored. If the surface is reached during the decompression alarm, the arrow <STOP> continues flashing, in order to point to the risk of a decompression accident. The SOS-mode is activated 3 minutes after the dive. If the total (cumulative) duration of the decompression alarm is longer than a minute it is entered in the logbook.

5.2 Desaturation time

Aladin Sport Plus is in surface-mode. The arrow <DESATURATION> appears; beside desaturation time in hours and minutes is displayed. Desaturation time is continually indicated until the next dive or until it reaches zero. The display is switched off to save energy 3 minutes after the last manipulation (surfacesleep-mode). Desaturation calculations continue to be made in the background.
In some cases, desaturation times with the Aladin Sport Plus are considerably longer than those of other models. 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 Plus are desaturated and it switches into the sleep-mode

Recommended response of the diver During the dive: Observe the decompression prescription shown by Aladin Sport Plus After the dive: Watch out for symptoms of arterial gas embolism and decompression sickness. Seek immediate medical attention at a recompression chamber should any signs or symptoms of decompression sickness appear. Before the next dive, plan a sufficiently long interval (display <Atn> should disappear).
An exessive ascent rate can lead to serious injury or death from decompression sickness. Failure to seek IMMEDIATE treatment for any signs or symptoms of decompression sickness after a dive may result in serious injury or death.
Situation 2: Reaction of computer:
The diver disregards the prescribed decompression depth. The model calculates the formation of bubbles due to ignoring decompression. Waiting time at the displayed decompression stage is extended or a lower decompression stage is displayed in order to assure sufficient time for desaturation.
Recommended response of the diver During the dive: Avoid decompression dives. Descend to the prescribed decompression depth at once. Do not descend to greater depths during the dive. Observe the decompression prescribed by Aladin Sport Plus. After the dive: Watch out for symptoms of arterial gas embolism and decompression sickness. Before the next dive, plan a sufficiently long interval (display <Atn> should disappear). Failure to comply with all decompression information on the Aladin Sport Plus may result in serious injury or death due to decompression sickness. There is a risk of decompression sickness on every dive even if all precautions described in this manual are taken.
Situation 3: The diver is physically exerting himself or herself, (e.g. swimming against the current).
Recommended response of the diver During the dive: Avoid further physical exertion if possible. Relax. Extend decompression time at the highest stop if possible. After the dive: Refrain from heightened physical exertion on your next dive. Make sure the surface interval is long enough. It may be advisable to go on another dive only the next day.

Situation 4:

It is very unlikely to have a surface interval long enough to clear the <Atn> prior to the next dive during an organized dive trip from a boat. This previous buildup of nitrogen must be taken into consideration for the next dive. Aladin Sport Plus calculates a shorter no-stop time or decompression prescription to reduce the risk of decompression sickness.

Reaction of computer:

Recommended response of the diver During the dive: Dive conservatively on all repetitive dives. Limit your maximum depth to no more than 25 m at the very beginning of the dive and make a very slow ascent. After the dive: Before the next dive, plan a sufficiently long surface interval (<Atn> display should disappear).

When diving in spite of the display <Atn>, a clear shortening of the no-stop time and/or an extension of decompression has to be expected. If a dive is made during <Atn>-time, the <Atn>-time following the dive can increase considerably. Making a repetitive dive when <Atn> is displayed will increase your risk of serious injury or death from decompression sickness!
5 Leaving the Diveplan-Mode
If the contacts B and E are touched, Aladin Sport Plus falls back into ready- or surface-mode. This also occurs three minutes after the activation of the diveplan-mode.
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.

The Aladin Sport Plus is able to communicate with a personal computer. The connection is established by contact sensors and the MemoMouse. The MemoMouse and the PC software DataTrak and DataTalk is available as an option. For the Aladin Sport Plus it is only allowed to use DataTalk version 1.6 or higher. Communication with a personal computer (Windows) has a number of advantages: 1.1 Personal programming of the dive computer (DataTalk) By means of the Data-Talk-software you can choose, if depth is indicated in feet or metres. 1.2 Analysis and storage of real dives The last approx. 200 minutes of dive time are stored by the dive computer in increments of 20 seconds and can be transferred to the PC. The DataTrak software allows the representation and analysis of the profiles. By this means all relevant data are examined and displayed for every point in time. The DataTrak releases 1.6 and higher recognize the Aladin Sport Plus and display the respective data. The PC program enables the diver to keep a personal logbook. Apart from the last 200 minutes of diving, 37 dives are recorded in the logbook of Aladin Sport Plus. If the data from Aladin Sport Plus are transferred regularly into the MemoMouse and then to the PC, all dives will be stored in the PC with their profiles.Time and date of the dives are automatically recorded and the dives can be printed out on a page for the divers logbook. 1.3 Updates The last versions of DataTrak and DataTalk are available for free from the Internet (http://www.uwatec.com). These programs are backwards compatible but not for MS-DOS.

4 Safety considerations

The Aladin Sport Plus gives to the diver a high level of reassurance and safety. However these units can never be a substitute for a thorough diving education. Pay careful attention to warnings given by the Aladin Sport Plus. Do not make risky dives. Pay special attention to the parts of this manual which are marked with a warning sign. Follow all standard safe diving practices: Never dive without a buddy. The Aladin Sport Plus does not substitute for a dive buddy! Only make dives that are appropriate to your level of dive training. The Aladin Sport Plus does not increase your knowledge of diving. Do not dive deeper than 40 m. This manual is part of the Aladin Sport Plus safety concept.

I Introduction
1 Aladin Sport Safe No-Stop Diving
The proven no-stop dive computer Aladin is enhanced with a new, revolutionary calculation model which makes it even safer and more comfortable. The Aladin of the new generation is called Aladin Sport and is part of the Aladin family which also includes the air integrated Aladin Air X and the decompression computer Aladin Pro. Although the Aladin Sport is designed for nostop diving it does provide the minimum necessary information in the event of a dive requiring decompression stops. The new generation Aladin Sport provides an increased level of safety and more features together with its traditional ease of use.

the divers physical performance is lower than during the dive. By considering the differences in physical performance the no fly time becomes considerably longer. 2. The model considers inert gas not only in the dissolved state, but also in the gaseous phase (microbubbles). Formation of microbubbles is calculated with allowance for the different influences in arterial and venous blood. With normal ascents gas bubbles mainly form in venous blood, with fast ascents also in arterial blood and on ignoring decompression stops in the tissues. As the model calculates microbubbles, those physiological processes are reconstructed which actually occur. The bubbles on the venous side of the circulation are carried into the lungs where they change the arterial nitrogen pressure. This influences mainly repetitive dives, dives with very long decompression times and the no fly time.
Gross disregard of the ascent rate, exceeding the decompression depth and repeated ascents to the surface (yoyo dives), can all cause microbubbles to form on the arterial side and in tissues. Where the bubbles partially impair circulation, the rate of gas diffusion and the saturation tolerance are changed. No-stop-time, decompression time, and if necessary decompression depth, are adjusted so that existing bubbles stop growing. In addition, altered decompression assures that the tissue desaturates sufficiently if microbubbles impair circulation locally. The calculation of the gas bubbles results in a new ascent instruction. The ascent rate near the surface is reduced down to 7m/min. This prevents with high reliability the formation of microbubbles in the arterial circulation and minimizes the formation of microbubbles in the venous circulation after the dive. 3.2 Advantages On first dives with correct diving technique and avoiding risk situations, there are no extended decompression times. On the other hand, it is possible to react correctly in risk situations due to the realistic simulation of the physiological processes in the body. This increases safety considerably. Risk situations are, for example: Repetitive dives (especially with short intervals) and dives on several successive days Dives in cold water Yoyo dives Flying after the dive
In case of mistakes on the part of the diver, actual prevention of decompression sickness is possible for the first time due to the reconstruction of the bubble formation and its consequences. The correction of the decompression must not be confused with a real recompression, which serves as therapy of already existing damage.
With its new decompression model Aladin Sport offers a so far unreached level of safety. However, responsibility for the dive finally remains with the diver as before. The usual diving caution is still absolutely necessary when diving with Aladin Sport. In case of diver mistakes (ignoring decompression stops, excessive ascent rate etc.) Aladin Sport can calculate a corrected ascent instruction immediately which minimizes the occurrence of decompression sickness. The prevention of barotrauma and nitrogen narcosis still lies in the hands of the diver. Aladin Sport is a highly developed technical instrument of high reliability. Despite this, the user of the Aladin Sport is to have an understanding of the physiological interrelations, to know the use of decompression tables and to have them with him on every dive. Should an incident occur, the detailed previous history of the incident is stored in the dive computer. The evaluation of these records allows better diagnosis and the most effective treatment for the diver.

II Aladin Sport Survey

1 The Aladin System
The potential of the Aladin Sport computer is expanded by the additional of accessory items.
1 During the dive the Aladin Sport dive computer supplies only the important dive and decompression information, plus warnings if necessary. It has a logbook with the last 19 dives and a dive planner.
2 The configuration software DataTalk (supplied together with DataTrak) allows the alteration of a number of preset parameters of Aladin Sport.

ma x. d
3 The external memory extension (ESE) makes it possible to read data from the logbook memory of Aladin Sport without a personal computer. This is especially valuable on diving holidays. 4 The logbook software DataTrak enables you to print out logbook pages. You can get a special logbook with insert folders from your retailer.

2 Operation

Switching on display: automatically, on submerging in water or when adaptation to atmospheric pressure is necessary. manually by operating contacts on housing. automatically, after three minutes without operation.

Switching off display:

Aladin Sport 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. Contact B: Base contact, which has to be touched for all operations Enter contact. It serves to switch on the computer, to activate the logbook and dive-plan-mode and to switch between no-stop and decompression planning. It is also used to confirm inputs and is therefore comparable to the ENTER- or RETURN-key of a computer. They serve to select the logbook and dive-plan as well as to set values (time, depth, dive-number etc.).

2.2 Operating modes

Aladin Sport works in various operating modes: Sleep-mode: Activation: automatically When Aladin Sport is not used it is in the so called sleep-mode. In this case, the electronics are sleeping for the most part, the display does not show any information. The computer is briefly activated once every minute to measure atmospheric pressure. The display remains switched off. If a change in altitude is recognized, Aladin Sport switches to -> surface-mode for 3 minutes. Ready-mode: Activation: By touching contacts B and E from sleep-mode. To check the display, all signs light up for 5 seconds.

max. depth depth

deco info dive time
Aladin Sport switches into ready-mode afterwards. In ready-mode, the display is switched on and in certain circumstances altitude sections are also displayed. On touching contacts B and E in ready-mode once more, Aladin Sport displays the remaining battery capacity in percent. Three minutes after activating readymode, Aladin Sport falls back into -> sleep-mode.
Dive-mode: Activation: automatically, when depth more than 0.5 m. In dive-mode all diving functions are monitored: i.e. depth and dive time are displayed, maximum depth is stored, saturation of tissues is calculated with allowance for temperature, no-stop time or decompression prognosis is determined, ascent rate is controlled and displayed and the correctness of the decompression procedure is supervised.

Wait-mode: Activation: automatically on reaching the surface. The wait-mode is activated when the surface is reached after a dive. At the surface, the dive is not closed and entered into the logbook for an interval of 5 minutes. This allows a short surfacing for the purpose of orientation.
Surface-mode: Activation: automatically after a dive or when changing altitude. After a dive has been closed, Aladin Sport is in surface-mode. All data belonging to the surface interval are calculated: Calculations are made on microbubble formation, on state of saturation of tissues after allowing for skin temperature and the assumed diver performance on the surface, on desaturation time and on no fly interval time. In order to save energy, Aladin Sport falls into the so called surface-sleep after 3 minutes. The functions of surface-mode are then carried out in the background. The atmospheric pressure is measured in surface-sleep once every minute.
If the atmospheric pressure decreases, for example because of change of altitude, Aladin Sport automatically switches from sleep-mode or from surface-sleep into surface-mode and displays the adaptation time. The adaptation time is the time after which all body tissues have adapted to the ambient pressure (= desaturation time).
Logbook-mode: Activation: manually by contacts Data of 19 past dives can be called up in the logbook mode. It shows, for example, maximum depth, dive time, preceding interval, altitude sections and, where appropriate, alarms. A dive is entered in the logbook if it has lasted more than 2 minutes. It also shows the interval which has passed since the last dive or a preceding change of altitude. By means of an interface Aladin Sport can be connected with an MS DOS personal computer. In that case, the last 37 dives and the last dive-profiles can be read out. The number of profiles depends on the length of the dives (a maximum total of 200 diving minutes).
Diveplan-mode: Activation: manually by contacts The diveplan-mode assists the planning of a future dive. It allows planning of nostop and decompression dives with freely determinable depth and dive time. On repeat dives, the surface interval can be chosen at will. Calculations are based on the temperature data of the last dive and assume a normal workload.

Warning of bubbles. Extension of the surface interval is recommended. See pages 36 and 57.

2.2 Alarms

An alarm occurs in the following situations: Excessive ascent rate. Reduce ascent rate.
Ignoring decompression stop Descend to the prescribed decompression depth at once!

In dive-mode, <bAt> is indicated by flashing display and alternating with the display of maximum depth, as soon as battery capacity is 0%. In ready-mode and surface-mode, <bAt> is shown instead of maximum depth. Have the batteries changed by your retailer!
3 Preparation for the Dive
Basically, Aladin Sport need not be switched on manually. When submerged in water, the contacts are bridged by the water and the dive computer switches into dive-mode directly. It is advisable to check the functions immediately before the dive in the diving location:
1 Switching on Aladin Sport manually. Bridge contacts B and E with moistened fingers. Check test display: Are all displays lit?
2 The Aladin Sport is now in ready-mode. After three minutes without operation or submerging in water, Aladin Sport switches off the display. It need not be switched on again. It switches on automatically on submerging in water and activates the dive-mode as soon as a depth of more than 2 feet is reached. The display of the depth may appear a little delayed. In extremely pure freshwater, it may occur that automatic activation of dive-mode does not work. On descending Aladin Sport responds to the increase in pressure and switches into > dive-mode. There may be a delay of up to 1 minute.
4 Functions during the Dive
4.1 Dive time The whole time spent below a depth of 1.2 metres is displayed as dive time in minutes. While the dive time is running, the colon on the right of the figures is flashing at 1 second intervals. Maximum dive time displayed is 199 minutes.
If a dive lasts longer than 199 minutes, the dive time display starts again at 0 minutes, because the display cannot show a larger figure.

4.2 Current depth Current depth is given in 10 cm increments. On switching on and at a diving depth of less than 0.5 m the void display <> appears.
Depth measurement is based on freshwater. Therefore, Aladin Sport shows a slightly greater depth than actually true when diving in salt water, depending on the salinity of the water.

4.3 Maximum depth

The maximum depth is only displayed if it exceeds the current depth by more than one metre. This is to prevent the display changing very frequently when diving in the vicinity of the maximum depth.

max. depth deco info

4.4 Ascent rate
Optimal ascent rate varies between 7 and 20 m/min dependent on the depth. It is displayed in percent of the set value. If the ascent rate is bigger than 100% of the set value, the black arrow <SLOW> appears. If the ascent rate exceeds 140%, the arrow starts flashing.

Messages

Ascent rate

Optical alarm

The prescribed ascent rate has to be observed. Excessive ascent rate can lead to microbubbles in the arterial circulation. Reduce ascent rate!
It is possible that Aladin Sport demands a decompression stop within the nostop phase because of the danger of the formation of microbubbles. Decompression time necessary for the prevention of microbubbles can increase massively, if the ascent rate is exceeded. From great depth, too slow an ascent causes super-saturation of tissues and an extension of decompression timeand total ascent time. From little depth, shortening of decompression times is possible because the tissues already start desaturating during the ascent.
4.5 Decompression information No-stop time is displayed, if no decompression stops are necessary yet. The arrow <NO STOP> is visible. The figures indicate no-stop time in minutes.
No-stop display <99:> means remaining time of 99 minutes or more. No-stop time is calculated assuming normal workload and current water temperature.

Messages:

In the last minute of the no-stop phase the no-stop display shows the flashing value <0>.

Action:

In order to prevent a decompression dive, you have to ascend a few metres after this message.

Decompression values

On entering the decompression phase, the arrow <NO STOP> extinguishes. The arrow <STOP> appears. Right beside the arrow, the lowest decompression stage in metres is displayed. Beside the decompression depth, the decompression time of the dipslayed stage in minutes appears. The display <6m> means that a decompression stop at a depth of 6 m has to be made. When a decompression stop has been finished, the next higher is displayed. When all decompression stops have been made, the arrow <STOP> 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. Arrow <STOP> flashes. Due to the formation of microbubbles decompression can increase massively while a decompression stop is ignored. If the surface is reached during the decompression alarm, the arrow <STOP> continues flashing, in order to point to the risk of a decompression accident. The SOS-mode is activated 3 minutes after the dive. If the total (cumulative) duration of the decompression alarm is longer than a minute it is entered in the logbook. Action: Descend to the prescribed decompression depth at once!

5.1 End of a dive

After reaching the surface, Aladin Sport switches into wait-mode automatically for five minutes. This is the time span necessary to recognize the end of the dive. The delay allows for coming to the surface for orientation and the resumption of the dive afterwards. When the dive is closed after 5 minutes in wait-mode, it is entered into the logbook and Aladin Sport switches into surface-mode. In surface-mode, Aladin Sport shows desaturation time and no fly time.

5.2 Desaturation time

Aladin Sport is in surface-mode. The arrow <DESATURATION> appears; beside desaturation time in hours and minutes is displayed. Desaturation time is continually indicated until the next dive or until it reaches zero. The display is switched off to save energy 3 minutes after the last manipulation (surface-sleepmode). Desaturation calculations continue to be made in the background.

In some cases, desaturation times of the new Aladin Sport are considerably longer than those of its predecessors, because the calculation model assumes reduced physical activity at the surface and calculates with shorter half-time periods. If desaturation time reaches the value 0, all tissues are desaturated. Aladin Sport switches into sleep-mode.

5.3 No fly time

The waiting period until the next flight is indicated as follows: <DO NOT FLY>; beside, time in hours. In some cases the no fly time is considerably longer than with previous models (reason: see desaturation time).
The no fly time must be strictly observed because of the danger of the formation of gas bubbles.

5.4 Warning of bubbles

Through repetitive dives microbubbles accumulate in the lungs if the surface interval is not long enough. Ignoring decompression or an excessive ascent rate can also lead to bubbles in tissues. In certain circumstances, in order to reduce the risk through further repetitive dives, an extended surface interval should be planned. The prognosis on the formation of bubbles during the surface interval allows Aladin Sport to advise the diver to extend the surface interval. If the display <Atn> (=attention) is visible instead of the depth during the surface interval (surface-mode), the diver should extend the surface interval. The extension of the interval prevents a high concentration of bubbles in the lungs during the planned dive and avoids a risk situation.
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.
Aladin Sport also measures the atmospheric pressure in sleep-mode. If the computer detects a higher altitude section, 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.
The entire altitude range is divided into four sections which are influenced by meteorological circumstances. That is why the following altitude sections overlap on their fringes. The altitude section is indicated at the surface, in the logbook and in the dive planner by stylized mountains, if a mountain lake altitude is reached. Section 0 is not indicated. In the following, you can see the approximate altitude ranges of the four sections:

After the dive:

Situation: The diver is exposed to exertion for a long period (e.g. in a current).
Recommended action of the diver During the dive: Avoid further physical exertion if possible. Make a break for relaxation. Extend decompression time at the highest stop if possible. After the dive: Refrain from intense physical exertion on your next dive. Make sure that the surface interval is long enough. It may be advisable not to go on another dive on the same day.
Situation: It is impossible to have a sufficient surface interval so that the indication <Atn> would extinguish prior to the next dive (e.g. on organized diving trips from a boat). Aladin Sport calculates a more conservative no-stop time or decompression prescription in order to allow nitrogen in the vicinity of bubbles enough time for desaturation.

Reaction of computer:

Recommended action of the diver During the dive: Be careful to have a profile 'low in bubbles' on your next dive (limit depth to 25 m max., slow ascent). Before the next dive, plan a sufficiently long interval (display <Atn> should have disappeared).

VI Dive Planner

The Aladin Sport is equipped with a dive planner which allows the planning of no-stop and decompression dives with freely determinable surface intervals. The water temperature of the most recent dive and present altitude sections are incorporated in the calculation. The Aladin Sport does not allow the planning of decompression dives.

3. Contacts B and E afterwards activate the planning mode.
4. The display shows no-stop times for increasing depths (scrolling no-stop times, see page 57, planning of a no-stop dive).
3 Selection and Activation from Surface-Mode
1. From surface-mode, you switch into the dive-plan input stage by B and.
2. The display shows<DIVEPLAN>. You return to surface mode by B and +.
3. After confirming by B and E, the display shows <Add>, <Int> and the interval (flashing). Aladin Sport expects your input for the duration of the dive interval.
4a. If no surface interval is to be entered, (diving at the present moment), confirm this with contacts B and E, and you switch into no-stop planning.
4b. You can extend the interval with contacts B and +. B and shorten the interval.
5. You confirm the new interval with B and E and get to no-stop planning (page 57).
4 Planning a No-Stop Dive
After confirming the surface interval (if possible), no-stop times are displayed in 3-metre-increments. The process starts at the deepest depth where the no-stop time is for the first time less than 99 minutes. The no-stop time for every 3-metreincrement is displayed for about 3 seconds (scrolling no-stop times).
Repetitive dives usually cause more microbubbles in the lungs than first dives if the surface interval is not long enough. Too rapid ascent and/or disregard of decompression instructions can lead to microbubbles. By calculating the formation of bubbles, Aladin Sport is able to advise the diver to extend the surface interval if necessary. If <Atn> is displayed instead of the depth in addition to the no-stop times, the diver should plan an extension of the interval if possible. This reduces the risk of many microbubbles in the lungs for the planned dive.
By repeated recalculations of the dive-plan with varying surface intervals the minimum interval can be found out. When diving in spite of the display <Atn>, a clear shortening of the no-stop time and an extension of decompression has to be expected. If a dive is made during <Atn> -time, the <Atn>-time following the dive can increase considerably.
5 Leaving the Dive-Plan-Mode
If the contacts B and E are touched for about 3 seconds, Aladin Sport returns to ready-mode or surface-mode. This also occurs three minutes after the activation of the dive-plan-mode.
