Just got a new IQ-750 and while going through the setup I ran into a little problem. My 700 P02 is set at 1.4 for mix 1 and 1.6 for mix 2. It appears the 750 P02 is set the same for both gases. Am I missing something. If that is the way it is supposed to be I don't like it. Help me out guys.

HI-
The IQ-700 PO2 is set for Mix 1 (21-50%) at 1.4 and Mix 2 (21-99%) at 1.6. You can't change the preset PO2 alarms, so if you wanted to dive at 1.6 or less you would need to dive Mix 2. You can't set the PO2 alarm or change the PO2 settings.
The IQ-750 PO2 alarm can be set from 1.2 to 1.6 in .1 increments in the Set A mode, outlined on page 33 of the user manual. The Mix 1 and Mix 2 are set, but the alarm can be set as desired.

I still have a problem. In set mode A I can set the P02; no issues there. However, when the comp calculates the mod it calculates for both mixes based on the P02 I just set in set mode A.
I don't see any way to set the P02 individually for mix 1 and mix 2. That means if I plan on doing deco on 02 I have to set my P02 at 1.6. If I set it for 1.4 the comp sets the alarm at 13 ft. for mix 2. If I set it for 1.6 it gives me a mod of of 132 ft for a 32% nitrox mix. I want to be able to set my P02's for both individual mixes. My question is how do I do that? I don't see anything in the directions that allows for that and I do believe that is a desirable function. Sorry to be a pest but I don't see how to do it.
