thanks for clearing that up for me.
i appreciate your help and will continue to check out this forum from time to time

i have a couple of questions. first, i am new to this forum but i have been using my cpap for 6+ years. i honestly didn't know there was a venue such as this. i am glad to know there are people to share my experience with and to gain experience from. however, i'm not sure about the tone people take ...

Thank you to those who helped me.
I am not stupid enough to do something I shouldn't, but I also don't believe it is necessary to make a visit.It took me 30 seconds and I saved gas, time & money!

where is the main power switch? on the back of my machine there is a cord coming out of a "little door" I can't get the door open and i don't see a power switch of any kind anywhere else.

i also need to change the pressure on my machine. where is the master switch to turn the machine off-someone said it is on the back of the machine. i see a cord in the back with a door of some kind but i can't get it open
