Info on RP System One CPAP

Hello,

I have been reviewing your site. Several years ago I just gave up and I stopped using my CPAP machine and sold it. Lately I have my sleeping has really decline, so I am going to have to restart therapy. I have the chance buy a used Respironics System One Auto.

I am not familiar with the new machines. So that I will know what I am getting, I would like to be able to know how many hours the machine has been used.

Can any of you tell how to check the machine to determine the usage?

Thanks and this seems like a really great site!

Hi again,

Disregard the the request.

I found the link to http://www.apneaboard.com and found the information regarding Hours of Use.
