Mask Setting?

I am using a quattro fx and a prs1auto bipap and was wondering what my setting should be in system one resistance. It is currently set to x1 but the quattro has no number as this machine only uses the Repironics mask numbering system. Any Ideas?

It is not a critical issue. There are no Resistance settings for non Respironics masks. You can set it to zero if you wish.
It won't affect leak rate reported. The setting is not designed for affecting the reporting of leak.
If one setting happens to "feel" better, that is fine but I have mine set to zero. I tried the settings..could feel no difference and leak reports didn't change with change in settings.
