Second Treatment... Are These Settings Right?

I just had my second treatment yesterday! Yay! It was a very different experience from my first. It felt cold and wet, and there was a tube of compressed-something attached to the laser head. I snapped a quick picture of the settings after the technician left the room. I’m getting my bikini done, and I have coarse, medium to dark-brown hair. Are these settings right for me? What do they mean? I’ve attached the picture.
