adjust a 209 remrest?

My 209 no longer seems to kick out sufficiant pressure. I just perchased a new mask, so that is not the problem. Can anyone tell me how to increase the pressure from 5 to 6.......My Apnea must be getting worse

I would guess that a screw located in the back of the machine would likely be what would adjust the pressure. If it has an LCD screen, that will likely show you what the pressure is. If it doesn't, then you may need and external manometer to see what pressure it is putting out.

Please keep in mind that is only a guess.
