Pro Nitrox – More Safety in Diving
4. Aladin ® Pro Nitrox always calculates considering the gas mixture set by the user. It is essential to check the
mixture calculation before each dive and to compare it to the gas mixture to be used. Maximum deviation
from the mixture calculation must not exceed 1% O
2
. A wrong gas mixture can be lethal!
5. Aladin
®
Pro Nitrox has a ppO
2
-warning, the default-limits of which are set at 1.5 bar ppO
2
max
. This limit can
be adjusted via Interface/Data Talk in the range of 1.2 to 1.95 bar. An alternation of the ppO
2
max
to higher
than 1.6 bar is risky and is not recommended.
6. Frequently check the „oxygen-clock“ (CNS O
2
Limit), especially when the ppO
2
is greater than 1.5 bar. Close
the dive if the CNS O
2
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 O
2
Limit has dropped below
40%.
8. Aladin

Pro Nitrox is a personal instrument like any other diving computer. This still applies when diving with
compressed air (21% oxygen) between two nitrox-dives. Aladin ® Pro Nitrox can be adjusted to compressed
air and then also includes the calculation of the CNS O
2
Limit in the same way as with any other nitrox-dive.
9. Always remember: setting a wrong mixture causes either insufficient decompression calculations or a too
low calculation of the oxygen-toxicity!
