1 SAFETY CONSIDERATIONS
WARNING
You must carefully read and understand this entire manual before using your Scubapro Aladin
TEC 3H.
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 3H.
Guidelines for the use of Aladin TEC 3H
The following guidelines for using Aladin TEC 3H 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 3H is designed for dives with compressed air (21% O
2) and Nitrox (22 to 100% O2)
only. Do not use Aladin TEC 3H 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
2. An incorrect gas mixture can be lethal!
• Only use Aladin TEC 3H for diving with an independent breathing apparatus. Aladin TEC 3H 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 3H has a ppO
2 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 3H 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 3H 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 5m /15ft)
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 3H does not substitute for a dive buddy.
• Only make dives that are appropriate to your level of dive training. Aladin TEC 3H does not
increase your knowledge of diving.

ENGLISH
Safety considerations
• 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).
• 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 3H! 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
• 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
• 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 71, or battery replacement,
see page 76) 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 3H prohibits via the flashing altitude range
number (see page 30).
2% status has dropped below 40%.
is visible on the display.
Flying after diving
• After diving, wait at least 24 hours prior to flying.

Repeated activation of the backlight will reduce battery life.
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 TEC 3H monitors the battery level throughout
every dive, and if the available energy drops below the warning threshold, Aladin TEC 3H will
automatically disable the backlight to prevent a computer shut down.

4.1.3 Nitrox information (O2 information)
For dives with compressed air in normal recreational diving, nitrogen is the decisive gas for the
decompression calculations. When diving with Nitrox, the risk of oxygen toxicity rises with the increase
of the fraction of oxygen and the increase of depth and can limit dive time and the maximum depth.
Aladin TEC 3H includes this in the calculations and displays the necessary information:
O
2% mix Fraction of oxygen: The fraction of oxygen in the Nitrox mixture can be set between
2 max Maximum allowed partial pressure of oxygen: the higher the fraction of oxygen in
ppO
When you enter the settings for the gas mixture, Aladin TEC 3H will display the
21% (normal compressed air) and 50% in 1% increments. Your selected mix will be
the basis for all calculations.

of oxygen is reached. The depth at which ppO2 max is reached is called Maximum

• The CNS O
2% 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 O
2 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.

4.2 Attention messages and alarms
Aladin TEC 3H 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.
F
• In addition, the sound can be turned off ompletely in "set 2" ->73.
• The audible attention messages can be swtched off in "set 1" ->70 or LogTRAK.
With LogTRAK they can be switched off selectively.
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 3H.
4.2.1 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.

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 3H 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 45 for further reference.
For CCR dives please read page 52 for further
reference.
To set the gas mixture, Aladin TEC 3H must be in
