Gas mix number flashes on the screen
To change gases underwater:
1. Press button A.
The back light turns on and the mix number flashes.
2. Press button B to select a mix number.
The O2 and HE percentages change to the programmed mix
and the PO2 indicator changes to reflect the PO2 for the
selected mix.
Note: Only the mix numbers that have been programmed
with a gas mixture are available.
3. Press button A to lock in the mixture and return to the
primary diving mode screen.
Note: You cannot lock in a mix if it causes you to exceed a
PO2 of 1.4 or 1.6 atmospheres, depending on what was
programmed.
Changing Setpoints Underwater
Because the NiTek X has the ability to be used with a closed-
circuit rebreather, you can switch between different PO2
setpoints while underwater. When you change setpoints, the
computer displays the current mixture you are breathing.
Note: Only switch setpoints when you have reached a safe
operating depth for the PO2 you are switching to.
