The S9's manual states that the Autostart feature won't work (at least for starting it) with a full face mask.
Thanks a lot sgearhart. I certainly hadn't noticed that. In fact I've just been over my manuals again and can't find that message. I guess what we are really talking about is called "smart start" and I have in "on".
If you have the Ramp feature turned on, the S9 will always employ it whenever you start the machine. OK that clears that one up for me.
The S9 has a peculiar behavior that requires the the unit to be totally powered down (power cord removed) for a few minutes in order for certain features to be reset after a change. It is a hit and miss as to which feature. Thanks for the tip, I shall watch out for that.
I shall try again tonight but not switch the unit off. thanks for your interest . . . Roger
Another plan might be to set the ramp time to a minimum say 5 minutes. So if you're using Cpap the pressure will return to the treatment level slowly.
I have this machine and use the start/stop button if I need to get up. I unclip my mask instead of doing what you do.

I use a full face mask and autostart works just fine on my S9 with my AirFit F10. It also worked with my previous Quattro FX. It doesn't stop or start immediately, it takes a breath or two to start and will stop after a few seconds. I'd try to reset and check the setting again. I think PsycoMike has the answer.
AutoStart vs. FFM on S9 varies with the version levels of hardware and software. On early models, setting FFM in the menu disabled autostart. It's also iffy, even when it's enabled with FFM. Some people find it works fine, some find it is iffy, some find it doesn't work. You can usually cover the anti-asphyxia vent with your hand and inhale and exhale a few times to make it work.
Turning the machine on and off with the button should work in all cases.
