What settings to use for Spectra s2?

I switched from breastfeeding to pumping in the middle of the night, last night. I’m only 6 days PP and I just don’t want to exclusively breastfeed (I could feel the anxiety creeping in like it did with my first). I have the Spectra S2. I have been pumping every 2 hours and have been getting on average .75-1.25 oz on each side, per session.

I have no clue how to use the settings and what cycle and speed to use to get the optimal pump.

Any ideas? :)
