Safety considerations
You must carefully read this entire manual before using your Aladin® Pro.
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
WARNING
The Aladin® Pro is a sophisticated decompression tool to assist a trained and certified diver in making
decisions concerning dive planning and execution. As with any tool, the Aladin® Pro may be misused
if the following safety and operational precautions are not strictly followed. If they are followed,
careful use of the Aladin® Pro 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® Pro is a technically advanced tool based on a biophysical model of decompression
sickness, neither it nor any other diving computer (or table) can actually 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. Not only that, but each individual diver‘s own susceptibility may vary from
day to day. Combined with the fact that decompression modelling is an inexact science, and of
necessity must be based at least partly on certain unproven assumptions, it is incumbent upon you,
the individual diver , to dive responsibly and to carefully follow all standar d safe diving practices as well
as the admonitions contained in this manual.

careful fashion, 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® Pro!

Safety considerations
Guidelines for the use of Aladin® Pro:
The following guidelines for using Aladin® Pro 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
will not occur.
– In accordance with the recommended maximum diving limit of all instructional agencies, do not dive
deeper than 130 feet.
– Do not use the Aladin® Pro for planned decompression diving. The decompression algorithm contained in
the Aladin® Pro should be used only for emergency or unintended decompression.
– On all dives with the Aladin® Pro, make a safety stop for three to five minutes within the ten to thirty feet
zone.
– Never use the Aladin® Pro for repetitive, “square“ dives deeper than 60 feet. A square dive is a dive that is
performed for its duration at a uniform depth.
– Always make the deepest dive of the day first when repetitive dives are planned, and for each successive
dive make sure that the deepest portion of that dive is done at the beginning of the dive.
– The Aladin® Pro is designed for dives made with compressed air only. Do not use the Aladin® Pro for dives
made with nitrox or other mixed gases.
– All divers using dive computers to plan dives and indicate or determine decompression status must use
their own computer.
E
Operating Manual Aladin® Pro
Safety considerations
– If the Aladin® Pro 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) 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.
– Y ou should not dive for a period of twenty-four hours befor e activating the Aladin® Pro to use it to plan or
control your diving.
– You MUST follow the ascent rates as indicated by the Aladin® Pro, and should the computer fail for any
reason, you must ascend at a rate of no greater than 60 feet per minute.
– You MUST be familiar with all signs and symptoms of decompression sickness before using the Aladin
Pro! Seek IMMEDIA TE treatment for decompr ession sickness should any of these signs or symptoms occur
after a dive! There is a direct correlation between the efficacy of treatment and the delay between the
onset of symptoms and the treatment for decompression sickness.
– Always observe the optical and acoustic alarm signals of the Aladin® Pro. Avoid situations of increased risk
for decompression sickness which are marked with a warning sign in this operating manual.
– Never dive the Aladin® Pro to the limit. Neither the Aladin® Pro, nor any other diving computer or
decompression table should be pushed to its limit. Give yourself a margin of safety by always leaving at
least a few minutes in the “no-stop“ box before making your ascent.
– Avoid repeated ascents and descents (yo-yo diving) while using the Aladin® Pro.

1. Aladin® Pro - With More Safety
The impressing operational features and its aspects
of safety and quality make Aladin® Pro an outstanding
diving computer. Building on the proven technique
and finish the Aladin® Pro has now been made safer
and more comfortable by incorporating
a new, revolutionary calculation
model.
Aladin® Pro desplays 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.
The Aladin® Pro of the
new generation brings
you in possession of a
device that guarantees
more safety, quality and comfort in diving.
Read this operating manual carefully and to the
last page.

I Introduction
2. Aladin® Pro - Your Personal Companion
Aladin® Pro considers your individual reactions during
the dive, the cooling of your skin and includes your
workload by a constant value in the calculations.
The latest results of medical and technical research
were taken into consideration. As a special feature
the calculation model also considers the formation of
micro-bubbles in the venous circulation depending on
workload and skin temperature.
This has led to the development of a unique, adaptive
calculation model.
Aladin® Pro was exclusively designed for diving with
compressed air and distinguishes itself from previous
models and other commercial diving computers in a
number of significant ways.
• The ZH-L8 ADT decompression calculation model
considers eight body tissues as well as the diver‘s
conduct and the ambient conditions. This allows
for an even more precise calculation of a modeled
risk for decompression sickness which can lead to
greater diving safety.
• Compared to all previous models the Aladin® Pro
I Introduction
I
is much more of a personal instrument, which
considers the individual conduct of the diver.
Different conducts of diving buddies can lead to
distinctive differences in the display of the
decompression information, since risk situations
(violations of the diving rules) may have a strong
influence by the anticipation of physiological
processes. On the other hand, Aladin® Pro
“rewards” a diving conduct following the rules
with highest diving comfort.
• The diver‘s workload is incorporated in the
decompression calculations as a constant value.
The new calculation model considers for the
calculation of the surface intervals and the
decompression information for repetitive dives that
the physical performance at the surface is less than
during the dive.
• The Aladin® Pro uses both optical and acoustic
alarms. The acoustic alarm uses varied sound
signals to assist in establishing the reason for the
alarm.
3
2. Aladin® Pro - Your Personal Companion
WARNING
You must strictly observe all optical and acoustic
alarms and take appropriate action based upon
those alarms to avoid serious injury or death from
decompression sickness!
• By using the Aladin® Pro‘s logbook, a diver may
directly call up information from the last 19 dives.
When interfaced with a personal computer, 37
dives and 200 minutes of dive profile in intervals
of 20 seconds can be read out.
• The dive planner allows the advance planning of
no stop dives with readily determinable surface
intervals.
WARNING
Although the Aladin® Pro can be used to plan
decompression dives, such dives are beyond
the realm of recreational or sport diving and must
not be attempted by recreational or sport scuba
divers.
• Aladin® Pro is designed to be mounted on the
diver‘s wrist or built in consoles. Ease handling,
easy to watch and unambiguous arrangement of
the data in the display, increase of diving safety
without the loss of diving comfort and the
possibility of transferring data to a personal
computer are the main features of the Aladin® Pro
comfort.

I Introduction
3. The Calculation Model ZH-L8 ADT
3.1 Description
The Aladin® Pro 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 body‘s organs
is not constant. Skin and muscle tissues
are especially subject to changes in
blood perfusion, depending on temperature and workload. Changes in blood
perfusion to these organs change their
nitrogen saturation tolerance. The model used by
the Aladin® Pro takes these effects into account
and thus the “skin“ and “muscle“ compartments
in the Aladin® Pro show variable half-time periods
and saturation tolerances.
Decompression information is calculated according
to the workload and decrease in skin temperature.
I Introduction
I
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, depend-
ing upon the depth, time, and temperature of a
dive, as well as the diver‘s
workload
during that
dive.
5
3. The Calculation Model ZH-L8 ADT
2. The decompression model used by the Aladin
Pro 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® Pro 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 body‘s tissues as
well. If a particular dive profile may result in the
creation of microbubbles according to the Aladin
Pro‘s 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 body‘s 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 requir ed, both
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® Pro, 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.

I Introduction
3. The Calculation Model ZH-L8 ADT
3.2 Advantages
On the first dives following responsible diving
procedures, a diver using the Aladin® Pro should never
be required to decompress, although a three to five
minute safety stop between ten and thirty feet is
recommended for every dive. If, however, unplanned
circumstances arise during the dive which increase the
risk of decompression, the Aladin® Pro can, if closely
followed, reduce the risk of decompression sickness
by reducing remaining bottom time and/or increasing
decompression time. Some of the more common risk
situations are as follows:
• Repetitive dives, especially those deeper than 60
feet and those with short surface intervals.
• Repetitive dives using square dive profiles.
• Repetitive diving over the course of several
successive days.
• Diving in cold water.
• Y o-yo diving (repeated descents and ascents to the
surface during a given dive).
• Flying within 24 hours after diving.
I Introduction
I
If a diver experiences any of these risk factors while
diving, the Aladin® Pro will decrease remaining bottom
time without requiring decompression, or will add
required decom-pression time in order to help
minimize the risk of decompression sickness.
WARNING
Do not use the Aladin® Pro for planned decompression dives!
If signs or symptoms of decompression sickness occur
after diving with Aladin® Pro, seek IMMEDIATE
treatment at the nearest recompression facility.

4. Safety in Diving
With its new decompression model the Aladin® Pro is
an extremely versatile tool which can increase your
diving comfort and safety. As with any diving tool,
however, ultimate responsibility for diving safety
remains with the individual diver . The same responsible
diving practices taught by all diving certification
agencies are still absolutely necessary in order to safely
dive with the Aladin® Pro.
Certain mistakes which may be made by a diver , such
as ascending at an excessive rate, going too deep, or
staying too long at depth, may be overcome if the
diver carefully follows the Aladin® Pro‘s corrected
ascent instructions. Of course, the Aladin® Pro can do
nothing to prevent the occurrence of lung
overexpansion injuries or nitrogen narcosis, whose
avoidance lies solely with the individual diver . The Aladin® Pro is a highly sophisticated technical instrument
which, if used and maintained properly , will have high
reliability. Despite that, no dive should be made with
an Aladin® Pro without a thorough understanding of
decompression theory and dive table use, and every
diver must have a set of decompression tables with
him on every dive.
WARNING
Do not use the Aladin® Pro without a set of
accepted diving tables with you as a back up
decompression tool on every dive.
Should decompression sickness occur, whether the
Aladin® Pro was used correctly or not, a detailed history
of the previous dives may be used to allow a better
diagnosis and the most effective treatment for the
diver.

Wait-mode:
Activation: automatically on reaching the surface.
The wait-mode is activated if the diver surfaces (diving depth less than 2 ft). 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.
Surface-mode:
Activation: automatically after a dive or when changing altitude.
After a dive has been completed, Aladin® Pro is in surface-mode. All data belonging
h
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® Pro 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® Pro switches from sleep-mode or from surface-sleep into surface-mode 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).
