SAFETY CONSIDERATIONS
You must carefully read and understand this entire manual before using your Scubapro Aladin TEC 3G.
WARNING
Diving has many inherent risks. Even if you follow the instructions of this manual in a careful manner, it is still
possible that you may be seriously injured or die from decompression sickness, oxygen toxicity or some other
inherent risk of scuba with Nitrox or compressed air. 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 3G.
Guidelines for the use of Aladin TEC 3G
The following guidelines for using Aladin TEC 3G 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 3G is designed for dives with compressed air (21% O
Do not use Aladin TEC 3G 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%O
• Only use Aladin TEC 3G for diving with an independent breathing apparatus.
. An incorrect gas mixture can be lethal!
2
Aladin TEC 3G 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 3G 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 O
). Ascend and finish the dive if the CNSO2 exceeds 75%.
2
• 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 3G gives no
warning about this.
• On all dives, with or without dive computer, make a safety stop for at least 3 minutes at 5metres
(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 3G fails at any time during the dive, the dive must be terminated, and appropriate
surfacing 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 3G does not substitute for a dive buddy.
• Only make dives that are appropriate to your level of dive training. Aladin TEC 3G 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.
) and Nitrox (22 to 100% O2) only.
2
1
• 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
TEC 3G! 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 recognized institution.
Repetitive dives
• Do not start your next dive before your CNSO
% status has dropped below 40%.
2
• 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
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 90, or battery replacement,
see page 99) 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 3G prohibits
via the flashing altitude range number (see page 38).
Flying after diving
• After diving, wait at least 24 hours prior to flying.
Aladin TEC 3G dive instrument is compliant with the European Union directive 2014/30/EU.
Standard EN 13319: 2000
Aladin TEC 3G dive instrument is also compliant with the European standard EN 13319: 2000 (EN 13319: 2000 – Depth gauges and
combined depth and time measuring devices – Functional and safety requirements, tests methods).

2.2.8 Displaying the date
From the time of day display you can display the date by pushing 1x or 2x (depending on whether
there is desaturation time left).
The display switches back to the time of day display after 5 seconds without operation.
2.2.9 Checking the battery condition
Battery condition / performance
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 TEC 3G displays the estimated remaining battery performance for 5 seconds as a bar graph.
If the bar graph shows 3 segments the battery warning appears ->23 and the battery has to be
replaced ->99.
WARNING
• 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 nish a dive.
• Replace the battery when the steady battery symbol appears (3 segments)!

System and operation
NOTE: The temperature inuences 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.

ENGLISH
2.2.10 Active backlight
The display of Aladin TEC 3G can be illuminated both on the surface and underwater.
The backlight can be activated by pushing . The light will turn off automatically. The default duration
is 6 seconds. The duration can be changed in “set 1” (->84) or with LogTRAK between 2 and 12
seconds. It can also be set to “push on / push off”, in which case the light stays on until you turn it off
by pressing again.
The backlight can only be activated if the computer display is on.
NOTE: Repeated activation of the backlight will reduce battery life.
NOTE: 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 rst 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 TEC 3G monitors
the battery level throughout every dive, and if the available energy drops below the warning
threshold, Aladin TEC 3G will automatically disable the backlight to prevent a computer shut down.
2.2.11 Switching off the display
From the time of day display you can switch off Aladin TEC 3G by pushing .
On the surface Aladin TEC 3G switches off automatically after 3 minutes without operation.
2.2.12 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: ->92 (“set 2”)

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 ->41. 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.
WARNING
• 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 behavior. Scubapro
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 LogTRAK software.

3.1.3 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
TEC 3G includes this in the calculations and displays the necessary information:
O
% mix Fraction of oxygen: The fraction of oxygen in the Nitrox mixture can be set between
2
21% (normal compressed air) and 100% in 1% increments. Your selected mix will be the basis for all
calculations.
ppO
max Maximum allowed partial pressure of oxygen: the higher the fraction of oxygen in the
2
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 TEC 3G will display the ppO2 max
limit setting and the corresponding MOD. Aladin TEC 3G warns you audibly and visually
once the depth is reached at which the ppO2 reaches the maximum allowed value ->30.
NOTE:
• Default setting of ppO2 max is 1.4bar.
The value of ppO2 max can be set by means of LogTRAK or with “set 1” between 1.2 and
1.6bar (->86). It can also be changed at the time of setting the gas mixture (->24).
• The CNSO2% 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.

3.2 Attention messages and alarms
Aladin TEC 3G 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.
NOTE:
• The audible attention messages can be switched off in “set 1” ->84 or LogTRAK. With
LogTRAK they can be switched off selectively.
• In addition, the sound can be turned off completely in “set 2” ->94.
WARNING
If you turn off the sound you will have no audible warnings. Without audible warnings you could inadvertently get
into potentially hazardous situations which could result in death or serious injury.
WARNING
Serious injury or death may result from failing to immediately respond to alarms given by Aladin TEC 3G.
3.2.1 Attention messages
Attention messages are communicated to the diver visually by symbols, letters or ashing gures. In addition,
two short audible sequences can be heard (in an interval of 4seconds) in two different frequencies under water.
4s (can be switched off)
Attention messages come up in the following situations (more information can be found on the listed pages):
23
Diving with Scubapro Aladin TEC 3G
• Maximum Operating Depth / ppO2 max is
reached 30
• Set max depth is reached 28
• Oxygen toxicity reaches 75% 31
• No-stop time less than 3 minutes 32
• Prohibited altitude (surface mode) 38
• Entering decompression
(when diving with L0) 32
• Half of set dive time is reached 27
• Set dive time is reached 27
• Depth for tank switch has been reached 64
3.2.2 Alarms
Alarms are given to the diver visually by ashing symbols, letters or gures. 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):
• Oxygen toxicity reaches 100% 31
• Ignored decompression 34
• Exceeding the prescribed ascent rate 29
(Particular scale of beeps, ->29)
• Altitude alarm 38
•

• MB no-stop time = 0 49
• MB level stop ignored 50
• MB level reduced 51
• Entering decompression when diving
with MB level L1-L5 52
• Apnea mode alarm 44
3.3 Preparation for the dive
You have to check the settings of Aladin TEC 3G especially before the first dive. All settings can be
checked and changed directly at Aladin TEC 3G or via LogTRAK.
3.3.1 Setting the gas mixture and ppO
max
2
WARNING
Before every dive and after changing the tank, make sure that the settings for the gas mixture correspond with
the current mixture used. An incorrect setting causes Aladin TEC 3G 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 2 or 3 gas mixtures please read page 59 for further reference.
For CCR dives please read page 66 for further reference.
To set the gas mixture, Aladin TEC 3G must be in user mode (time of day display).
