When you dive with an SCR with Oxy2 and Aladin
®
Air Z O
2
you will know your exact decompression, CNS
clock status, Oxygen fractions and ppO
2
on line and in real time. With Aladin
®
Air Z O
2
paired to a pres-
sure transmitter or Oxy
2
you dive more safely than ever before, though you can make more of your diving
time thanks to the exact calculation of the gas-supply. In addition, Aladin
®
Air Z O
2
offers an unmatched
comfort in carrying and operation. Aladin
®
Air Z O
2
gives you increased safety due to it`s calculation model.
All the information necessary for safe diving are combined in one instrument.
With the Aladin
®
Air Z O
2
you are – due to it`s multi-function – ready for the future.
The Aladin
®
Air Z O
2
can increase both your diving pleasure and safety by reducing your risk of decom-
pression sickness provided you carefully follow the instructions and guidelines given you in this manual.
Unlike previous diving computers, which only base their decompression information on depth and time
data, the Aladin
®
Air Z O
2
also considers temperature and diver workload, which are known to be addi-
tional risk factors for decompression sickness. By considering these risk factors as well as monitoring your
exact supply, the Aladin
®
Air Z O
2
allows you to plan and execute dives with a greater degree of safety
than with previous models of decompression computers.
The Aladin
®
Air Z O
2
and the Oxy2 are not to be used with closed circuit
rebreathers.
Please read this operating manual carefully and to the last page.
If you are using an Oxy2, you must also carefully read the Oxy2 manual.

– More Safety in Diving
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 describes a mixture with a higher percentage of
oxygen. A higher percentage of oxygen (and automatically the reduction 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.
