The last time I had it in to get adjusted, I tried to watch the tech as he did it. The bastard took my unit, hunched over it and did some magical crap with the controls and had it changed in nothing flat...
So tonight I have done a web search in earnest to find out how to do it. I think the last sleep study they screwed up and the settings are too low anyway.
So I found this site: http://www.cpaptalk.com/CPAP-Sleep-Apnea-Forum.html
I have found the instructions for my unit and soon hopefully will be sleeping like a baby.
I may have to kill the damned cat if he doesn't stay off the thing though.
