DANGER: Do not dive with cylinders containing Nitrox mixes without having
verified personally the oxygen percentage in the mix.
IMPORTANT: before diving, always verify the setting for the %O2 parameter
(oxygen percentage) on the computer!
This can be done at surface level, from the main DIVE screen and the DIVE
SET screen, which provide a quick view of the parameters previously set.
IMPORTANT: Keep in mind that time underwater being the same, a Nitrox
mix requires longer decompression times than Air. It is essential to adhere
strictly to the max depth values permitted by the Nitrox mix used.
DIVING WITH NITROX
During a dive with a Nitrox mix conducted within the safety curve, besides all the
info associated with a normal Air dive, the following data will also be given:
• Bar chart showing the current O2 toxicity level for the CNS.
• NITROX GAS1 icon, or GAS2 icon (CARTESIO).
• The mix currently used (GAS 1 or GAS 2 CARTESIO)
NITROX mode : Diving with nitrox.
The memory of the GOA/CARTESIO computer retains the Oxygen percentage
%O2 value entered previously until this parameter is changed manually by the
diver.
Hence, it is important to realise that:
Articial breathing mixes pose extremely severe risks to a person’s health if they
are not perfectly known, analysed and studied in all aspects to do with diving
activities. It is essential to understand that THE MIX YOU BREATHE MUST BE
PERFECTLY IDENTICAL TO THE ONE SET ON THE COMPUTER. OTHERWISE
THE INFORMATION on decompression and toxicity of the gas SUPPLIED BY THE
COMPUTER WILL POSE A RISK TO HUMAN LIFE. Before, during and after a NI-
TROX dive, it is imperative to check the oxygen percentage and ensure it matches
exactly the percentage of oxygen in the scuba diving cylinder.
BEFORE A NITROX DIVE.
The GOA/CARTESIO computer keeps the Air dive mode always active until the
scuba diver sets it to Nitrox mix mode. In this case, the display will show the
NITROX icon, which remains visible throughout the dive and as long as the GOA/
CARTESIO computer remains set to NITROX MODE-S. To enable the computer
to adjust its computation algorithm according to the new parameters, once the
Nitrox program has been activated, it is necessary to enter the exact value of the
oxygen percentage (%O2) contained in the cylinder that you are going use, after
conducting a careful analysis of the content thereof.
DANGER: The use of this computer with hyper-oxygenated (NITROX) mixes
is reserved for divers who have successfully completed a training course on
the use of such mixes.
