I understand why they might want to lock out patients from the settings, but it's strange that they bother to hide important therapy data. When I asked, My DME told me the machine could not show more data then the usage hours. Now I wonder whether he is incompetent or outright lying.
The problem is, at least in Germany, that I cannot choose the DME. The contracts go between DME and insurance, and insurance only worries about costs.
It appears that the machines come from the factory with most things set to the dumb/evil option by default.
Sleep quality usage, Ramp=45/4, EPR off, etc.

If it's midnight and a DME tells you it's dark outside, go and check it yourself.
