BiPAP Auto M series Provider mode

Does anyone know how to get into provider mode? I have tried unplugging my unit and then plugging it in holdown the - Button. Nothing happens. I am new to this and only have the user guide. I am having touble with the exhale pressure and want to reduce it while it get used to the system. Thanks

Unplug unit, hold down both arrow buttons while plugging it back in. Then press + button to enter setup mode. then press right arrow key or left arrow to move back and forth thru menu. Hope this helps. If I remember correctly, this is the way 'tis done. How are you doing with your M auto bipap? Add your equipment at the bottom of your profile and then we can see what you are working with.

If you're doing it correctly you'll hear two beeps as the machine starts up. Also, press the power button to exit the provider menu once you've changed your settings.
