4.2 Enriched Air Nitrox diving use
This device can be used with nitrox breathing gases (also known as oxy-nitrogen).
The maximum nitrox breathing gas oxygen concentration is 40%.
WARNING: Do not use nitrox gas mixtures if you do not have proper training.
Appropriate training courses about nitrox and oxygen diving are essential prior to
the use of this kind of equipment with oxygen content greater than 22%.
WARNING: In nitrox use, the maximum operating depth and exposure time are
dependent on the oxygen content of the gas.
WARNING: There is a danger when using nitrox that contaminants may give rise
to an oxygen ignition.
WARNING: The use of breathable air according to EN 12021 may contaminate
the diving apparatus.
NOTE: To minimize the risk of oxygen ignition, pressure vessel valve(s) should
always be opened slowly.
4.3 Oxygen calculations
The oxygen calculations are based on currently accepted exposure time limit
tables and principles.
By default in Air/Nitrox dive mode, CNS% and OTU values are not displayed until
they reach 80% of their recommended limits. When either value reaches 80%,
Suunto EON Steel notifies you and the value stays in the view.
• Audible alarm when pO
2
value exceeds the preset limit (pO
2
high alarm)
• Audible alarm when pO
2
value is < 0.18 (pO
2
low alarm)
WARNING: WHEN THE OXYGEN LIMIT FRACTION INDICATES THAT THE
MAXIMUM LIMIT IS REACHED, YOU MUST IMMEDIATELY TAKE ACTION TO
REDUCE OXYGEN EXPOSURE. Failure to take action to reduce oxygen exposure
after a CNS%/OTU warning is given can rapidly increase the risk of oxygen toxicity,
injury, or death.
NOTE: You can customize views to always show CNS% and OTU.
