F&P SleepStyle 200 cpap machine adjustment

Help...anyone out there!!! I was using nasal pillows at a #8 pressure but my mouth was leaking so Dr. bumped me up to 10. It was of course worse. So....I took matters into my own hands and set the machine back to 8. The tech walked me thru it. Since that time I've now graduated to a full face mask (F&P 431) and my wife is now catching me snoring a bit WITH MY EQUIPMENT ON !! I'd like to move this setting back to 10 but I've forgotten how to do it. Can anyone walk me thru resetting it????
