PR Series APAP set up

[breathright]

Iim a 4yr CPAP user new to APAP and I'm interested in setting up an optimal range. My 90% is is reporting 9cm and I've set it for 7cm low and 12cm high as a start point. Also when in CPAP mode is the 90% # the suggested place to start" I understand that I will need to try different settings to get my best results but without available software I'll have to fly by LCD AHI reading and how I feel. I would go back to my M Series or Tank so I could use Encore Pro but I do like the way I sleep with this new PR. Best feature so far has been no rain out (I call it water boarding) Its also quieter than my M but not as quiet as my trusty old Tank. Thanks
