Operating Manual Aladin®Pro
You must carefully read this entire manual before using your Aladin®Pro.
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 standard safe diving practices as well
as the admonitions contained in this manual.
Safety considerations
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
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!

Operating Manual Aladin®Pro
Guidelines for the use of Aladin®Pro:
The following guidelines for using Aladin®Pro are derived from the latest medical research and the
recommendations oftheAmericanAcademy ofUnderwater Sciencesfor divingwith divingcomputers. Following
theseguidelineswillgreatly increase yoursafety whilediving,but cannotguarantee thatdecompression 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.

Operating Manual Aladin®Pro
– 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.
– You should not dive for a period of twenty-four hours before 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 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. 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.

The impressing operational features and its aspects
ofsafetyand qualitymakeAladin®Proanoutstanding
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 infor-
mation 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 them-
selves 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.

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
decompressioninformationforrepetitivedivesthat
thephysicalperformance atthesurface islessthan
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.
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-bubblesin thevenouscirculationdependingon
workload and skin temperature.
Thishasledto the developmentofa 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
