Safety considerations

I UWATEC Aladin TEC 2G

You must carefully read and understand this entire manual before using your

Aladin TEC 2G

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. Unless you are fully aware of these risks and are willing to personally accept and assume responsibility for those risks, do not use

Aladin TEC 2G

Guidelines for the use of Aladin TEC 2G:

The following guidelines for using Aladin

TEC 2G are derived from the latest medical research and the recommendations of the American Academy of Underwater Sciences for diving with diving computers. Following these guidelines will greatly increase your safety while diving, but cannot guarantee that decompression sickness or oxygen toxicity will not occur.

• Aladin TEC 2G is designed for dives with compressed air (21% O2) and Nitrox (22 to 100% O2) only. Do not use Aladin TEC 2G for dives made with other mixed gases.

• It is absolutely necessary to check the set mixture before each dive and to compare it to the gas mixture currently used. Always remember: setting an incorrect mixture carries an inherent risk of decompression sickness and/or oxygen toxicity! Maximum deviation from the measured mixture must not exceed 1%O2. An incorrect gas mixture can be lethal!

• Only use Aladin TEC 2G with open circuit breathing systems.

• Only use Aladin TEC 2G for diving with an independent breathing apparatus. Aladin TEC 2G is not designed for long term exposures with Nitrox.

• Always observe the visual and audible alarm signals. Avoid situations of increased risk which are marked with a warning sign in this operating manual.

• Aladin TEC 2G

has a ppO2 warning. The default limit is set at 1.4bar ppO2 max. It can be changed

between 1.2 and 1.6bar.

• Frequently check the "oxygen clock" (CNS O2). Ascend and finish the dive if the CNS O2 exceeds 75%.

• Never dive deeper than the Maximum Operating Depth (MOD) pertinent to the gas mixture in use.

• Always check the diving limits considering the oxygen content and standard sports diving procedures (decompression sickness, oxygen toxicity).

• In accordance with the recommended maximum diving limit of all instructional agencies, do not dive deeper than 40 metres/130 feet.

•

The danger of nitrogen narcosis has to be taken into consideration

. Aladin TEC 2G gives no warning

about this.

• On all dives, with or without dive computer, make a safety stop for at least 3 minutes at 5 metres (15 feet).

• 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 Aladin TEC 2G

fails at any time during the dive, the dive must be terminated, and appropriate surfac-

ing procedures (including a slow ascent and a 3 to 5 minute safety stop at 5

metres /15 feet

) should

be initiated immediately.

• Comply with the ascent rate and carry out any decompression stop required. If the computer should fail for any reason, you must ascend at a rate of 10m (30ft) per minute or less.

• On any given dive, both divers in a buddy pair must follow the most conservative dive computer for that particular dive.

• Never dive without a buddy. Aladin TEC 2G

does not substitute for a dive buddy.

• Only make dives that are appropriate to your level of dive training. Aladin

TEC 2G

does not increase

your knowledge of diving.

• Always dive with back-up instruments. Make sure that you always use back-up instrumentation including a depth gauge, submersible pressure gauge, digital bottom timer or dive watch, and have access to decompression tables whenever diving with a dive computer.

• Avoid repeated ascents and descents (yo yo diving).

WARNING

English

I UWATEC Aladin TEC 2G

• 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 TEC 2G! 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 O

% status has dropped below 40%.

• When 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 no-dive warning NO 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 47, or battery replacement, see page 51) 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 (13000ft).

• After a dive do not rise to altitudes that Aladin TEC 2G

prohibits via the flashing altitude

range number (see page 29).

Flying after diving

• After diving, wait at least 24 hours prior to flying.

Aladin TEC 2G

dive instrument is 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.

Important remarks concerning signal words and symbols

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.

We thank you for choosing Aladin TEC 2G and we hope you will enjoy safe dives in the future! Further information on UWATEC dive computers and other products by UWATEC can be found on our web page at www.scubapro-uwatec.com. To make this manual easier to read we will use the term "Aladin" as an abbreviation for "UWATEC Aladin TEC 2G diving computer" throughout this booklet.

Safety considerations Dive computers provide divers with data; they, however, do not provide the knowledge how this data should be understood and applied. Dive computers cannot replace common sense! You must therefore carefully read and understand this entire manual before using your Aladin.

Downloading your dives

Aladin’s memory allows you to store approximately 25 hours of dive profile information in 4 second sampling intervals. With SmartTRAK you can transfer this information to the PC in order to visualize and analyze your dives on the monitor. To download data from Aladin, click on "NEW" under the "LOGBOOK" menu to open and name a new logbook or open an existing logbook. Then click on the "TRANSFER DIVES" icon: a box will appear on the screen identifying the computer being downloaded, and a progress bar will show the status of the transfer. You can choose between transferring all dives or new dives only (default setting) from Aladin’s memory. If you choose to transfer new dives only, SmartTRAK will only transfer dives that are more recent than the most recent dive already saved in the PC logbook. To transfer all dives, you must change the default setting by selecting "Transfer" under "Dives" in the main menu bar.

Once the data is downloaded, a window will show you a summary table of all dives; for the selected dive, another window will show you its details. From these windows you can add and edit your dive information.

WARNING

Bar graph interpretation

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).

Aladin displays the estimated remaining battery performance for 5 seconds as

a bar graph. If the bar graph shows 3 segments the battery warning appears

->19 and the battery has to be replaced ->51.

• If the bar graph shows 2 segments, the battery symbol will blink, on the surface and in dive mode, to alert the diver of a dangerous situation: the battery may not have enough energy to finish a dive.

• Replace the battery when the steady battery symbol appears (3 segments)!

The temperature influences the battery performance. In cold water it is lower than in warm water. If the battery shows 4 segments on the surface, it is possible for it to drop to 3 segments during the dive. If this is the case, the backlight will be temporarily disabled. See below.

Aladin

marks dives started with 3 or less segments in the logbook with the

battery symbol.

Logbook information is not lost even when the battery is removed for a long

time.

Activation: automatic If the diver remains above a depth of 0.8m (3ft) for more than three minutes without observing a prescribed decompression stop, the computer will automatically switch into SOS mode after the dive.

Push to see the "SOS" sign and the remaining length of the SOS mode. The dive will be entered in the logbook with "SOS".

The SOS mode will be unlocked after 24 hours.

While in SOS mode, the computer cannot be used for diving. The computer can however be used in gauge mode ->30. All segments in the nitrogen loading bar will flash throughout the dive.

Diving within 48 hours after the end of an SOS mode will result in shorter no stop times or longer decompression stops.

• Serious injury or death may result if a diver does not seek immediate treat

ment 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.

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 SmartTRAK software.

On the surface Aladin switches off automatically after 3 minutes without operation.

2.12 Alarm clock

The alarm clock goes off only at the surface. If the alarm clock is "on", the time of day display shows .

When alarm is triggered: flashes and special attention beeps are played for 30 seconds or until the user presses a button.

Setting the alarm clock: ->48 ("set 2")

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. Aladin monitors the battery level throughout every dive, and if the available energy drops below the warning threshold, Aladin will automatically disable the backlight to prevent a computer shut down.

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. 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 100% in 1% increments. Your selected mix will be the basis for all calculations.

ppO2 max 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 cor

responding MOD. Aladin warns you audibly and visually once the depth is reached at which the ppO2 reaches the maximum allowed value ->25.

•

Default setting of

ppO2 max

is 1.4bar.

The value of

ppO2 max can be set by means of SmartTRAK or with "set 1" between

1.2 and 1.6bar (->46). It can also be changed at the time of setting the gas mixture (->20).

• The CNS O2% value/alarm is not influenced by the selected ppO2 max 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 0.5bar, the CNS O2 value increases, if the partial pressure of oxygen is below 0.5bar, the CNS O2 value decreases. The closer the CNS O2 value is to 100%, the closer the limit where symptoms of oxygen toxicity can occur.

Nitrox diving may only be attempted by experienced divers after proper training from an internationally recognized agency.

2 Attention messages and alarms

III UWATEC Aladin TEC 2G

Aladin draws the diver’s attention to certain situations and warns the diver of unsafe diving practices. Attention messages and alarms are visual and / or audible.

• 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.

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.

III

2.1 Attention messages

Attention messages are communicated to the diver visually by symbols, letters or flashing figures. In addition, two short audible sequences can be heard (in an interval of 4 seconds) in two different frequencies under water.

Attention messages come up in the following situations (more information can be found on the listed pages):

Page

• Maximum Operating Depth / ppO

max

is reached 25

• Set max depth is reached 23

• Oxygen toxicity reaches 75% 25

• No-stop time less than 3 minutes 26

• Prohibited altitude (surface mode) 29

•

Entering decompression

(when diving with L0)

• Half of set dive time is reached 22

• Set dive time is reached 22

•

Diving with MB levels (L1-L5):

• MB no-stop time = 0 34

• MB level stop ignored 35

• MB level reduced 35

• Entering decompression when diving with MB level L1-L5 35

2.2 Alarms

Alarms are given to the diver visually by flashing symbols, letters or figures. In addition, an audible sequence in one frequency can be heard during the whole duration of the alarm.

An alarm occurs in the following situations (more information can be found on the listed pages):

Page

• Oxygen toxicity reaches 100% 25

• Ignored decompression 27

• Exceeding the prescribed ascent rate 24 (Particular scale of beeps, ->24)

• Altitude alarm 29

• Low battery alarm (without audible alarm): the battery icon appears if the battery has to be replaced. 51

until

3.1 Setting the gas mixture and ppO2 max

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. If the fraction of oxygen is set too low this can lead to oxygen poisoning without warning. If the value is set too high decompression sickness may occur. Inaccuracies in the calculations are carried over to repetitive dives.

For dives with two gas mixtures please read page 37 for further reference.

To set the gas mixture, Aladin must be in user mode (

time of day display).

1. Push

or until the GAS 1 O

menu appears.

Confirm that you wish to change the oxygen fraction of gas 1 by pushing .

3. Change the oxygen fraction in increments of 1% by pushing or . Aladin will display the current fraction of oxygen, the maximum partial

pressure limit (ppO2 max) and the MOD.

4. Confirm the selected percentage with .

5. By pushing

or you can change the ppO2 max for the chosen fraction of oxygen down to 1.0bar. Aladin will now display the corresponding MOD for the new ppO2 max.

6. Confirm your ppO2 max settings with .

4 Functions during the dive

III UWATEC Aladin TEC 2G

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), 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. depth and dive time displayed, max depth stored, saturation of tissues calculated, no-stop time or decompression prognosis determined, ascent rate controlled and displayed and the correctness of the decompression procedure supervised.

4.2 Setting bookmarks

During the dive you can create bookmarks in your dive profile by pressing . The logbook icon appears for 4 seconds and an audible signal confirms the creation of the bookmark. These bookmarks will be graphically displayed in the dive profile of SmartTRAK.

4.3 Dive time

The whole time spent below a depth of 0.8m (3ft) is displayed as dive time

in minutes. The time above 0.8m (3ft) is counted as dive time only if the diver descends again below 0.8m (3ft) within 5 minutes.

While the dive time is running, the colons on the right of the figures are flashing

in one 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.

4.4 Current depth / O2% mix

4.6 Ascent rate

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. The

intensity of the alarm increases in direct proportion to the degree that the prescribed ascent rate is exceeded.

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 Aladin 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".

Reduce ascent rate

Excessive ascent rates for longer periods are entered in the logbook.

4.8 Oxygen toxicity (CNS O2%)

Aladin calculates oxygen toxicity based on depth, time and the gas mixture

and displays it in the location of the ascent rate. The toxicity is expressed in 1% increments of a maximum tolerated value (O2 clock).

The symbol "CNS O2" is displayed together with the percentage.

An audible attention signal goes off if oxygen toxicity reaches 75%. The symbol "CNS O2" flashes. Ascend to shallower depth to decrease oxygen loading and consider terminating the dive.

When oxygen toxicity reaches 100%, an audible

alarm goes off every 4 seconds. "CNS O2" and the percentage value flash. Danger of oxygen toxicity!

Start procedure for terminating the dive.

• During an ascent and if the CNS O

% 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.

• Aladin will display CNS O2% values exceeding 199% with 199%.

4.7 Partial pressure of oxygen (ppO2 max

) / Maximum Operating Depth (MOD)

The

maximum partial pressure of oxygen

ppO2 max

(default 1.4bar) determines the Maximum Operating Depth (MOD). Diving deeper than the MOD will expose the diver to oxygen partial pressures higher than the set maximum level.

The ppO2 max

and consequently the MOD can be reduced manually (->20, setting the gas mixture, point 5). In addition the maximum allowed ppO2 can be set by means of SmartTRAK or with "set 1" between 1.2 to 1.6bar ->46.

The MOD is a function of ppO2 max

and the mixture used. If during the dive the MOD is reached or exceeded Aladin sends an audible attention message and the MOD is displayed (flashing) in the lower left corner.

Ascend to a depth shallower than the displayed MOD in order to diminish the danger of oxygen poisoning.

The MOD should not be exceeded. Disregarding the warning can lead to oxygen poisoning.

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.

** Depending on your profile, the no-stop time may drop below 3 minutes before the upper 5 segments are lit. In this case, only those seg-

ments that are lit will flash.

If you have entered decompression, the 6th segment will turn off as soon as you complete your last decompression obligation to indicate that you are no longer in decompression.

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 influenced by the 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.

5.3 Desaturation time, No-fly time and No-dive warning

5 minutes after a dive Aladin shows the time of day, the "do not fly time", the no-dive warning (if applicable), the current altitude range and the prohibited altitude range (->29).

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 Aladin displays "do not fly" may lead to serious injury or death from decompression sickness.

If the "no-dive" warning is visible during the surface interval, the diver should not undertake another dive.

If Aladin detects a situation of increased risk (due to the potential of microbubble accumulation from previous dives or a CNS

O2 level above 40%), the no-dive symbol will appear on the display. The duration of the no-dive warning is visible in the dive planner menu. Aladin recommends this as minimum surface interval in order to reduce the number of microbubbles and/or to reduce the CNS

O2 level

below 40%.

You should not undertake a dive as long as the no-dive warning message is

displayed on the computer screen. If the warning is prompted by microbubble accumulation (as opposed to CNS O2 over 40%) and you dive anyway, you will have shorter no-stop times or longer decompression times. Moreover, the duration of the no-dive warning at the end of the dive can increase considerably.

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.

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. If the dive starts within this adaptation time, Aladin treats it as a repetitive dive, since the body is offgassing. Altitude is divided into five ranges, which are influenced by barometric pressure. That is why the defined altitude ranges overlap on their fringes. If a mountain lake is reached, the altitude range is indicated at the surface (time of day display), in the logbook and in the dive planner by a stylised mountain and the current altitude range.

V Diving with microbubble (MB) levels

V UWATEC Aladin TEC 2G

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. Dives within no-stop time and observance of decompression stops do not prevent the formation of microbubbles in the venous blood circulation. Dangerous microbubbles are those migrating into the arterial circulation. The reasons for the migration from the venous blood circulation to the arterial circulation can be a great many microbubbles collecting in the lungs. UWATEC has equipped

Aladin dive computers with a new technology to protect from microbubbles. The diver chooses – according to his/her needs – an MB level and influences through it the level of protection from microbubbles.

Diving with MB levels requires additional ascent stops (level stops), the ascent is slowed down and the body gets more time to desaturate. This works contrary to the formation of the microbubbles and increases safety

. Aladin features 6 microbubble levels (L0-L5). Level L0 corresponds to UWATEC's well-known decompression model ZH-L8 ADT and does not require level stops due to microbubble formation. Levels L1 to L5 offer additional protection from microbubble formation with level L5 offering the highest protection. Similar to the display of information during decompression dives or dives within no-stop time,

Aladin

displays depth and duration of the first level stop as well as the total time of ascent as soon as the MB no-stop time has run out. As the MB no-stop time is shorter than the ordinary no-stop time a diver will be required to carry out a stop (level stop) sooner than a diver using level L0. If a diver ignores a required level stop, Aladin will cascade to a lower MB level and the dive can not be completed with the initially chosen MB level. E.g. if a diver sets level L4 on Aladin prior to the dive and during the dive ignores the recommended stops Aladin will automatically adjust the setting to level L3 or lower.

1 Comparison of dives with MB level L0 and MB level L5

When two Aladin are used simultaneously, one unit is set for example to MB level L5, the other to L0, the no-stop time will be shortened and level stops will be required before the diver has the obligation of a decompression stop. These additional level stops help dissipate the microbubbles.

Whereas the quantitative information relative to L0 can be seen by pressing the right button, qualitative information is always visible on the display in form of the nitrogen loading bar. In particular, when the L0 no-stop time is less than three minutes, the nitrogen bar will flash ->26. This will help you avoid entering inadvertently into decompression.

3 Preparation for a dive with MB levels

V UWATEC Aladin TEC 2G

3.1 Setting the MB level

To change the MB level Aladin must be in user mode (time of day display).

1. Push or until the symbol for MB levels appears.

Confirm that you wish to change the displayed MB level by

pushing .

3. Change MB level by pushing or .

4. Confirm the selected MB level with .

Without confirmation the display will disappear after 3 minutes and your entries will not be accepted.

Aladin 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 2x

. If however a level stop is ignored, the new MB level is shown (->35).

MB levels have an influence on the dive planner.

4 Functions during the dive with MB levels

4.1 Level stop information

MB no-stop time

While diving with MB levels L1 to L5 Aladin 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. "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 (->26).

• No-stop time relative to L0 is shown by pressing 3x

(see )

• Regardless of the MB level, we generally recommend to perform a slow ascent during the last few metres / feet.

Level stop

On entering the level stop phase,

"NO STOP"

disappears and the arrow

STOP

appears. The

STOP

arrow flashes for 8 seconds and an audible attention beep goes off. To complete the dive without cascading to a lower MB level, all requested level stops must be observed.

The deepest level stop is displayed in metres (feet). The display "2: 3m "

("2: 10ft") means that a level stop of 2 minutes at a depth of 3 metres (10 feet) has to be observed. Deco information relative to L0 is shown on an alternate display (see ).

When a level stop has been finished, the next higher level stop – if present

– is displayed. When all level stops have been observed, the arrow

STOP

extinguishes and "NO STOP" reappears. The indication of time shows the MB no-stop time again.

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. To complete the dive without being reduced to a lower MB level, you must descend to the prescribed depth immediately!

The warning "MB level reduced" is activated if

the diver ascends more than 1.5m (5ft) above the required level stop. Aladin reduces the MB level, an attention beep* goes off and the new MB level is shown in the lower left corner.

To complete the dive without being further reduced

to an even

lower

MB level the new level stop must

be observed.

* Attention beeps can be suppressed with

set 1" (->47) or via

SmartTRAK.

Total time of ascent

Aladin displays the level stop information and the total time of ascent. This

includes the time of ascent as well as all level stops.

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%)

4.3 Decompression obligation

Aladin calculates and displays level stops to reduce microbubble formation, but

it also calculates the diver's decompression data.

Avoid decompression dives when diving with MB levels.

How to avoid decompression stops:

• Check ordinary no-stop time by pushing until L0 appears.

• Observe the nitrogen loading bar (it is relative to L0) ->26, ->33

• If the nitrogen loading bar flashes (less than 3 minutes to deco): ascend slowly a few metres/feet.

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.

If decompression stops become obligatory, the

DECO

symbol will be displayed.

The total ascent time will now also contain a decompression stop.

5 Complete a dive with MB levels

A dive with MB levels is completed the same way as a dive without MB levels

(L0) (->27), save for the following exceptions:

If the MB level has been reduced during the dive, Aladin 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 changes to user mode with the MB level switching back to the original MB setting.

Repetitive dives and MB levels: If during a dive a level stop is being ignored and the diver starts another descent shortly afterwards, Aladin might immediately request level stops. To complete the dive with the initially set MB level all level stops must be observed.

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

STOP

VI Diving with two gas mixtures

The following chapter deals with the characteristics of diving with two gases.

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

Depth

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.

Setting the gas mixture and the depth for changing the gas mixture

During dives with two gas mixtures the bottom mix (gas 1) contains the lower

fraction of oxygen. Aladin will only accept settings corresponding with this order.

For gas mixtures having an oxygen percentage of 80% or greater the pp

O2 is fixed at 1.6bar and

cannot be altered in any way.

Procedure:

1. Enter the setting for the fraction of oxygen and the pp

O2 max (MOD) for gas 1

(bottom mix) according to the instructions on page 20 (points 1-6).

Repeat the process in the GAS D

O2 menu to set the oxygen fraction and

O2 max for gas D. Note that in this case the resulting MOD corresponds to the depth at which you plan to switch from gas 1 to gas D during the ascent phase (switch depth).

3. If you set gas D

to "– –

O2%

", Aladin will compute the dive considering gas 1

only.

Aladin will only accept a gas switch depth (MOD gas D) as input where the maximum partial pressure of oxygen (pp

O2 max), as pre-set manually (->20

point 5) or by means of SmartTRAK, is not exceeded.

• During the ascent an audible and visual attention message will indicate that you have reached the depth which requires the change to gas D ->40.

• Without confirmation with the display will disappear after 3 minutes and your entries will not be accepted.

• If the deco gas option is turned on and the oxygen fraction of gas D is set to a value other than "--

O2%

", in surface mode and up to a depth of 0.8m Aladin will display "2G" in the lower right corner of the display instead of a percentage value.

VI UWATEC Aladin TEC 2G

Alternate displays during a dive with two gases

All displays time out after 5 seconds and the default display is shown again. (Only exception is the temperature, screen 2 below.)

The default display shows the predictive decompression prognosis, which assumes the diver will

switch to the deco gas at the specified switch depth. In the bottom left corner the temperature is displayed unless the current depth is 1m/3ft shallower than the max depth, in which case the max depth is displayed.

Upon pressing the right button, the temperature and the current O

% are shown in the lower row.

O2% will time out after 5 sec while the temperature remains.

Upon pressing the right button, "GAS 1" or "GAS d" appears in the middle row to indicate the cur

rently active gas and the MOD appears in the bottom left corner. "GAS 1" or "GAS d" will time out after 5 seconds unless the right button is pressed again.

In case that gas 1 is the active gas, pressing the right button one more time shows O

% of gas 1 in the bottom right corner and the decompression information in case the deco gas is not used (decompression information relative to gas 1 only). This is the calculation that Aladin would switch to in case, having reached the switch depth, the diver did not confirm the switch. The decompression information and the O2% blink.

If an MB level greater than L0 is active, pressing the right button one more time shows the predictive

decompression information and in the bottom left corner the currently active MB level.

Pressing the right button again shows the predictive decompression information relative to L0 togeth

er with the L0 symbol at the bottom left.

One more right button push shows the decompression information relative to L0 if only gas 1 is used,

with the decompression information and the O2% of gas 1 blinking.

Upon pressing the right button again, the time of day appears in the middle row.

• 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

"– – O

%" (->37, point 2) or you can turn off the deco gas option in SET 1. When you turn off the deco gas option in SET 1, the setting in the GAS D O2 menu remains but Aladin calculates the dive using gas 1 only.

If the deco gas option is turned off, the GAS D O2 menu will display OFF in the

lower left corner (instead of an MOD) and the ppO

setting will not appear.

VI Diving with two gas mixtures

Predictive decompression prognosis

The calculation of decompression data is based on the assumption that the change of gas mixture will be performed at the previously selected switch depth (MOD gas D). If a diver ignores the required change or changes the mixture belatedly, Aladin will readjust the decompression calculation accordingly. In case of an ignored switch the dive computer will then base its calculations on the assumption that the diver will ascend to the surface with gas 1.

WARNING

Functions during a dive with two gas mixtures

Diving with more than one gas mixture represents a much higher risk than diving with a single mixture, and mistakes by the diver may lead to serious injury or death.

During dives with several gas mixtures, always make sure you are breathing from the tank you intended to breath from. Mark all your tanks and regulators, so they can under no circumstances be mixed up! Before every dive and after changing a tank, make sure that each gas mixture is set to the correct value for the corresponding tank.
