IMPORTANT NITROX NOTE:
- If either mix is set to 22% or higher, the Quantum will default the FO
2
for that mix to
99% at midnight and display the mix as two dashes ( - - %); if either mix is set to Air,
it will stay set to Air indefinitely.
- If mix 1 defaults to a 99% FO
2
, it will be denoted by the flashing Nitrox label. This
99% default is built in to protect you from making subsequent nitrox dives with the
wrong FO
2
setting. If you make a dive with the FO
2
set to 99%, an audible alarm will
sound upon entering the water. Return to the surface and reset the FO
2
to the proper
percentage. If you continue the dive, you will reach the PO
2
limit at about 20 feet (6
m). Again, return to the surface and reset the FO
2
to the proper percentage.
- If Mix 1 defaults to 99%, the no-decompression and decompression calculations will be
calculated as though you were diving with normal air (79% nitrogen). Therefore, the
Quantum calculates a worst-case scenario (99% Oxygen, 79% Nitrogen). At worst, the
computer will be more conservative on subsequent dives.
- If only Mix 2 defaults to 99% (Mix 1 set to Air), you will only get an audible warning
when entering the water. Upon hearing the warning, return to the surface and reset the
Mix.
