Adjusting my REMstar pro2 w/C-flex myself

I've had this machine for 8-9 years, recently lost over 160 lbs. I've been having to tighten my mask so tight it's giving me headaches. Had a sleep test September last year. The tech said my pressure is OK I need to try a new mask, I've tried 5 different ones full face, nose only, nasal. I'm fine with the mask i'm using I just want to have the pressure turned down a few notches. i'm currently at 14. I'd like to just try to adjust it to see if it helps. The noise and the pressure are to much and i'm tired of arguing with the tech about it. Can anyone help me with this?

You have my favorite machine. (I have several of them)
Here are the instructions I wrote up years ago for getting into the setup and the options.

REMstar Pro 2 Setup

When in the Setup Menu, the humidifier ^ and ramp v buttons operate as up and down keys to change the settings, the left/right user buttons < > allow you to go to the previous/next question or setting, and the pressure start/stop button is used to exit the Setup Menu. Holding the humidifier or ramp buttons down will cause the values to change more quickly.

To enter the Therapy Setup Menu, hold the two top user buttons < > down while plugging in the power cord.
Continue holding the buttons down until the REMstar Pro 2 with C-Flex beeps twice.

Note: The word "setup" will appear on all of the screens indicating that you are in the Therapy Setup Menu.
If you press the Pressure start/stop button, you will exit the Setup Menu.

Thanks for your help. I'll give it a try. And yes I was lucky to get this machine, it's my third and by far the best machine I've ever used. Thanks again.
