I just got my S9 Autoset last week. I noticed the time is off by 2 hrs on my data in ResScan. Can I reset the clock inside my machine? Browsed the clinician manual and didn't see anything there. Did I miss it? You can reset the date and time without loosing any information. Go to the clinical menu,...

S9 uses the oscillating technology the PRS1 uses.......... at the moment I can't think of the name of the PR technology. So back to the other thing so even the NEW PRS1 are getting noise complaints? Funny PR says they are now the quietest 25% quieter than the S9. Why couldn't this be a a broken arm...

From the complaints on this board, I get the feeling that PRS1 machines get more noise complaints. Those with PRS1 sound problems seem to be complaining louder. There may be some bias due to factors such as more people owning PRS1. Even if the S9 is better, I don't think it's a big enough differenc...

As a physician, you should be able to afford both. Wasting your time worrying over which one is quieter is useless, as people hear and worry about sounds differently, and also the odd's of two machines making the same sounds are unlikely due to being built from different parts. Also the sounds you ...

I am also sorry to say I think this is a bunch of bunk. I also have permanent low Vit D levels, and take a pharmaceutical grade (prescription only) D3 supplement every month. Prescription D3 is available in Europe but not in the USA I have not noticed any difference in my OSA at all and my levels ar...

I must say I really like my Auto S9, but it is different than being on my PR System One Auto, on the S9 leaks or no leaks I often wake up tired and I must say a bit depressed.I first notice it after using the machine for about 3 months. I at first thought this was really just circumstance I then fo...

Everything I have read says leak under 24 on ResMed machine is acceptable. What is your AHI in these different scenarios? And of course, you have to go based on how you feel. Some nights I have zero leak with my S9. I run constant cpap mode pressure of 14. I do not have an auto. You know the leaks ...

I have another question. Despite the fact that I am a physician, I do not know everything. I have a ResMed S9 Autoset, previous to this I had a Respironics PR System One Autoset (older version), thus the post about if the new PR System One Auto is quieter than the ResMed S9 Autoset. I notice that on...

I have had a PR System One DS150 and now a Resmed S9 Autoset. Neither machine put out discernable noise sufficient to disturb most humans. Perhaps a human with dog-like hearing could differentiate between the machines or talk about dB level, but not me. Perhaps this my problem. I am a physician, an...

That video does not mean what many people think it does. It does NOT compare how much noise the machines make. It discusses "dynamic noise," i.e. how much the noise varies. "Static" noise is how noisy the machine is at any instant in time. "Dynamic" noise measures the difference between the highest...

So I guess that I am splitting hairs. I have talked with both Respironics and ResMed trying to figure this out. Respironics swears the new PR Stystem One Autoset is now quiter than the ResMed S9 Autoset due to the new motor and baffling built into the system.

Hi I am new here! I am having a really hard time trying to make a decision. I have a PR System One Autoset which is the old version V1.2 it is OK but kind of noisy. I recently got the newest machine from ResMed the S9 Autoset. Now the ResMed S9 is very quite I must say, but I have now been told that...
