Great Idea thanks

Does anyone know how to turn off this M Series Respironics unit? All that I can figure out is to unplug it. Has a power button but that seems to just turn on and off the blower. Am I missing something? Please help

Thanks Everyone! I will have to change my sleep pattern to incorporate back sleep patterns. Jay, yes I do sleep in my truck it has all of the comforts of home including kitchen sink.

I am new and have a full mask. when I roll onto my stomach I can can feel the air pressure escape under my chin. After 3 nights of sleeping on my back. I really need a solution to get back on my stomach and still get the proper therapy. Any suggestions? New mask?
