Safety considerations
You must carefully read this entire manual before using your Aladin® Pro Nitrox.
Diving has many inherent risks. Even if you follow the instructions of
this manual in a careful fashion, it is still possible that you may be
WARNING
The Aladin® Pro Nitrox is a decompression tool to assist a trained and certified diver in making decisions
concerning dive planning and execution. As with any tool, the Aladin® Pro Nitrox may be misused if
the following safety and operational precautions are not strictly followed. If they are followed, car eful
use of the Aladin® Pro Nitrox can increase your diving enjoyment and reduce your risk of decompr ession
sickness. If they are not, you will be placing yourself at serious risk for decompression sickness.
While the Aladin® Pro Nitrox is a technically advanced tool based on biophysical models of decompression
sickness and oxygen toxicity, 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.

Safety considerations
Guidelines for the use of Aladin® Pro Nitrox:
The following guidelines for using Aladin® Pro Nitrox 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.
– The Aladin® Pro Nitrox is designed for dives made with nitrox and compressed air ( 21% O2) only . Do not use
the Aladin® Pro Nitrox for dives made other mixed gases.
– It is absolutely necessary to check the set mixture before each dive and to compare it to the gas mixture
actually used.
Always remember: Setting a wrong mixture cause either insufficient decompression calculations or a too
low calculation of the oxygen-toxicity!
– In accordance with the recommended maximum diving limit of all instructional agencies, do not dive
deeper than 130 feet.
– Always check the diving limits given by the used share of oxygen.
– Do not use the Aladin® Pro Nitrox for planned decompression diving. The decompression algorithm contained
in the Aladin® Pro Nitrox should be used only for emergency or unintended decompression.
Operating Manual Aladin® Pro Nitrox
E
Safety considerations
– On all dives with the Aladin® Pro Nitrox, make a safety stop for three to five minutes within the ten to thirty
feet zone.
– Never use the Aladin® Pro Nitrox for repetitive, “square“ dives deeper than 60 feet. A squar e 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.
– All divers using dive computers to plan dives and indicate or determine decompression status must use
their own computer.
– If the Aladin® Pro Nitrox 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.
– You should not dive for a period of twenty-four hours before activating the Aladin® Pro Nitrox to use it to
plan or control your diving.
F
Operating Manual Aladin® Pro Nitrox
Safety considerations
– You MUST follow the ascent rates as indicated by the Aladin® Pro Nitrox, and should the computer fail for
any reason, you must ascend at a rate of no greater than 60 feet per minute.
– Y ou MUST be familiar with all signs and symptoms of decompr ession sickness before using the Aladin® Pro
Nitrox! Seek IMMEDIATE treatment for decompression 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 Nitrox. Avoid situations of incr eased
risk which are marked with a warning sign in this operating manual.
– Never dive the Aladin® Pro Nitrox to the limit. Neither the Aladin® Pro Nitrox, 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 Nitrox.

I Introduction
2. Introduction Aladin® Pro Nitrox
Nitrox is a gas mixture consisting of nitrogen and
oxygen. The kind of air used for diving with
compressed air is the same as the normal air of the
earth‘s atmosphere (78% nitrogen, 21% oxygen and
1% inert gases). Therefore, normal air is also Nitrox!
When talking of Nitrox as the breathing gas for diving,
it concerns a mixture with a higher share of oxygen.
A higher share of oxygen (and automatically the
reduction of the share of nitrogen) has the advantage
of lengthening the no-stop phase (or reducing the
decompression phase), since less nitrogen is dissolved
in the diver‘s body during the dive.
But the higher share of oxygen in the Nitrox-mixture
also causes additional physiological problems by the
toxic effects at a higher partial pressure of oxygen
(ppO2). When breathing oxygen at a higher partial
pressure, two kinds of oxygen toxicity can occur:
I Introduction
I
CNS damages:
Symptoms of poisoning occuring at short notice in
the central nervous system(CNS). Such symptoms
are: irritations of the respiratory organs, sickness,
headache, pulmonary oedema, cramps, unconsciousness. The symptoms occur at a ppO2 of more
than 1 bar and depend on the term of exposure and
on the partial pressure of oxygen.
Damages of the lungs:
Symptoms of pulmonary poisoning occuring in the
long run. The symptoms occur at a ppO2 from 0.5 bar
and higher and with terms of exposure in the range
of days/weeks.
Aladin® Pro Nitrox considers the short term toxic effect
of oxygen (CNS damages) by means of the so called
„oxygen-clock“. It is based on a list which showa the
units of toxicity for oxygen per unit of time in
dependence of the ppO2. The indication of toxicity
uses „CNS O2 %“ (= relative toxicity of oxygen for
3
2. Introduction Aladin® Pro Nitrox
the central nervous system). CNS O2 0% corresponds
to the normal state before the first dive, and CNS O
100% corresponds to the critical upper limit. The list,
initially published by the US Navy , is nowadays known
by the names IANTD- orNOAA-list. We modified this
list for the use with Aladin NitroX in cooperation with
Dr. Bill Hamilton, Hamilton Research Ltd. (Tarrytown,
NY), a well-known specialist.
The long-term kind of oxygen poisoning has practically
no relevance for diving with independent diving
equipment and is therefore not considered in the
design of Aladin Nitrox.
The physiological peculiarities of oxygen and the
changing decompression due to the reduced share of
nitrogen require a profound training, if nitr ox is used
for diving. Additional technical problems with the use
and the maintenance of parts of the equipment bear
further dangers when diving with nitrox. Therefore,
we recommend to adhere to the following guidelines
by all means.

I Introduction
2. Introduction Aladin® Pro Nitrox
WARNING WARNING
I
1. Only dive with nitrox if you have been trained
thoroughly by a recognised institution.
2. Only use Aladin® Pro Nitrox with open breathing
systems. Aladin® Pro Nitrox must be set for a
determined gas mixture. In partially-open and
in closed circulation-systems, the gas mixture can
vary considerably. The calculations may yield
results different from those necessary for the
actual muxture.
3. Only use Aladin® Pro Nitrox for diving with an
indepent breathing apparatus. Aladin® Pro
Nitrox is not designed for long-term exposures
with Nitrox.
I Introduction
4. Aladin® Pro Nitrox always calculates considering the gas mixture set by the user . It is absolutely necessary to check the set mixture before
each dive and to compare it to the gas mixture
actually used. Maximum deviation from the
measured mixture must not exceed 1% O2. A
wrong gas mixture can be lethal!
5. Aladin® Pro Nitrox disposes of a ppO2-warning,
the default-limits of which are set at 1.5 bar

2. Further Remarks on Aladin® Pro Nitrox
WARNING
6. Frequently check the „oxygen-clock“ (CNS O
Limit), especially in the range higher than 1.5
bar ppO2. Close the dive if the CNS O2 Limit
exceeds 75%.
7. Make sure you have a sufficiently long surface
interval, just as when diving with compressed
air. Oxygen also needs sufficient time to leave
the body. Go on the next dive only when the
CNS O2 Limit has dropped below 40%.
8. Of course, Aladin® Pro Nitrox is a personal
instrument like any other diving computer . This
also applies when diving with compressed air
between two nitrox®-dives. Aladin® Pro Nitrox
can be adjusted to compressed air (21% oxygen)
WARNING

and then also includes the calculation of the
CNS O2 Limit in the same way as with any other
nitrox-dive. Always remember: setting a wrong
mixture causes either insufficient
decompression calculations or a too low
calculation of the oxygen-toxicity!

I Introduction
3. Aladin® Pro Nitrox–Reducing Risks of Decompression Sickness
By considering your individual gas mixture, depth and
time profile and water temperature, the Aladin® Pro
Nitrox can be considered a personal diving control
instrument. Relying on the latest results of medical
and physiological research for its decompression
modeling, the Aladin® Pro Nitrox differs from earlier
diving computers in a number of significant ways:
I
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!
• The ZH-L8 ADT decompression calculation model
considers eight body tissues as well as the ambient
temperature. This allows for an even more precise
calculation of a modelled risk for decompression
sickness which can lead to greater diving safety.
• The Aladin® Pro Nitrox uses both optical and
acoustic alarms. The acoustic alarm uses varied
sound signals to assist in establishing the reason
for the alarm.
I Introduction
• By using the Aladin® Pro Nitrox‘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.
7
3. Aladin® Pro Nitrox - Reducing Risks of Decompression Sickness
WARNING
Although the Aladin® Pro Nitrox 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.
• The Aladin® Pro Nitrox is designed to be mounted
on the diver‘s left or right wrist, which offers the
maximum freedom of movement as well as easy
operation and use.
8
I Introduction
4. The Calculation Model ZH-L8 ADT
4.1 Description
The Aladin® Pro Nitrox 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 in particular 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® Pro Nitrox takes
these effects into account and thus the “skin“ and
“muscle“ compartments in the Aladin® Pro Nitrox
show variable half-time periods and saturation
tolerances.
Decompression information is calculated
I Introduction
I
according to the diver‘s individual behavior 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
diver's behavior during that dive.
9
4. The Calculation Model ZH-L8 ADT
2. The decompression model used by the Aladin® Pro
Nitrox 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 Nitrox 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 Nitrox‘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 RBT 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 Nitrox, 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
4. The Calculation Model ZH-L8 ADT
4.2 Advantages
On the first dives following responsible diving
procedures, a diver using the Aladin® Pro Nitrox 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 Nitrox 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).
I Introduction
I
• Flying within 24 hours after diving.
If a diver experiences any of these risk factors while
diving, the Aladin® Pro Nitrox will add required
decompression time in order to help minimize the risk
of decompression sickness.
WARNING
Do not use the Aladin® Pro Nitrox for planned
decom-pression dives!
If signs or symptoms of decompression sickness occur
after diving with Aladin® Pro Nitrox, seek IMMEDIA TE
treatment at the nearest recompression facility.
11
5. Safety in Diving
With its new decompression model, the Aladin® Pro
Nitrox 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 Nitrox.
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 Nitrox‘s
corrected ascent instructions. Of course, the Aladin
Pro Nitrox 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 Nitrox is a highly sophisticated
technical instrument which, if used and maintained
properly , will have high r eliability. Despite this no dive
should be made with an Aladin® Pro Nitrox 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 Nitrox without a set
of accepted nitrox diving tables with you as a back
up decompression tool on every dive.
Should decompression sickness occur, whether the
®
Aladin® Pro Nitrox 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.
