Thank you to all. Excellent insturctions. I do have one question. Item # 5 states to remove the data card from the computer operating system before removing card from printer. Not certain if I know what this means.

Printer Brother MFC 210 has memory slot used for photos to PC. Can the memory card from S9 be used to monitor software for the S9 without harming either the printer or PC?

Where can I go to change the language setting....?

How difficult is it to set and monitor the S9 Auto without the assistance of the medical supply company? I had difficulty previously setting a cpap and had to rely on the supply company. It is less expensive for me to purchase on line. I have a prescription.

I would like to purchase a new auto cpap. How does one learn the medicare requirements for upgrading an old machine to newer model? Also is it possible to manage without a local DME and purchase Apap on web as long as one has a sleep doctor? Thanks
