WARNING
It is essential to correctly set the
oxygen percentage in the breathing mix
to ensure correct readouts of:
- no decompression time remaining
- decompression stop times
- alarm for exceeding maximum
permitted PPO2.
!
WARNING
Do not use mixes with an O2% greater
than 50%.
!
WARNING
If you have completed a NITROX dive and
are planning a repetitive dive using
compressed air, set your dive computer
for NITROX mode with a % O2 of 21%. In
this way, the monitoring of the % CNS O2
will remain active.
