PPO2 Limits
This section allows changing of PPO2 limits�
All values are in absolute atmospheres [ATA] of
pressure� (1 ATA = 1�013 bar)
OC Low PPO2
PPO2 of all gases display in flashing red when less
than this value� (Default 0�18)
OC MOD PPO2
This is the maximum allowable PPO2 during the
bottom phase of the dive -
M aximum O perating
D epth� (Default 1�4)
This MOD setting is the same as can be edited in
Mode Setup (for Air and Nitrox modes) and in the
Nitrox Gases (for 3 GasNx mode)�
WARNING
Do not change these values unless
you fully understand the effect�
OC Min. PPO2 0.18
OC Mod. PPO2 1.40
OC Deco PPO2 1.61

OC Deco PPO2
All decompression predictions (Deco schedule and
TTS) assume that the gas used for decompression at
a given depth will be the gas with the highest PPO2
that is less than or equal to this value� (Default 1�61)
Suggested gas switches (when the current gas is
displayed in yellow) are determined by this value� If
you change this value, please be sure you understand
its effect�
For example, if lowered to 1�50, then a switch to
oxygen (99/00) will not be assumed at 6m/20ft�
Bottom Gases Vs. Deco Gases
In Air only and Nitrox modes, all gases are considered
bottom gases and obey OC MOD PPO2 limit, even in
decompression�
In 3 GasNx mode, the least oxygen rich mix is
considered a bottom gas and obeys the OC MOD
PPO2 limit� Other gases are considered deco gases
and obey Deco PPO2 limit�

Button Sensitivity
This menu allows some fine
tuning of button sensitivity�
This can be useful to adjust
downward if you often
experience accidental button
presses�
