Oceanic Atom 3.0 air settings

[hazmat]

I just used my new-to-me Atom 3.0 for the first time for a couple of dives off Lana'i in Hawaii. It'll take a little getting used to after being used to my Atom 2.0, but I can't find a setting like I remember in the 2.0 for plain air, not Nitrox. I know that Nitrox of 21% is air, but I remember there being a non-Nitrox air option in the 2.0. Anyone know if this is on the 3.0 and I'm just missing it? I looked in the manual, but we all know how bad the Oceanic manuals are.

Thanks.

Weird, now I do see Air setting, then it goes to 21%. Scratch this. I may have had it on 21% instead of Air. I'll have to see next time I dive with it.
