I get my CPAP machines for free from the VA. I also got an S9. I got it in Sept. 2013. The firmware version is 0907. I went from an AHI score or 21 to .4. But its weird because I actually do not feel any differently. I have been using my CPAP faithfully for over 4 years. The VA gives me as much free sh*t as I want, when I want. So I get a new hose and mask about every 6 months. I don't really bother with cleaning the machine all that much. When it starts to look dirty, I turn it in and they give me a brand new one right out the box!
I just downloaded the Res Scan software from y'all site today and its a lot of info / BS to look at. But I guess that many number is AHI and how often I actually use the machine (which is 100% of the time).
Anyone got a firmware version of higher than 0907? From reading the above, I guess the only way to get an update is to get a new machine. lol What a ridiculous method. But since it is a medical device and not, for instance, a printer or USB Video Camera, I guess for liability they got to do it this way.
thanks for all the great posts!
