I"m just a one "mask" man

I have one question. How often does your power go out that you even need to worry about all of this? I lost power in my house last year a total of 3 times and only once during the night.

Used system one and could not deal with the conductive noise it produced. Went with resmed 9 and could not be happier.

Can someone please PM me the link for rescan 3.11 software. I would like to upgrade from 3.10 . Thanks..............

I tried it and it did not work for me.......................
