i recently swapped a defective s9 for a supposedly new one under warranty. but the "new" machine has a noise problem. how may i be certain this is not a used machine? i'm returning it today for inspection, but i don't entirely trust the provider.

you can read the hours used via the clinician's menu. Press the info button and push-dial together for 3 seconds to get into the menu then navigate from there. (I'm working on my iPad at the moment and don't have my manual handy to be more specific).

thanks, deep breathing. rebooted last night, and machine returned to its quirky ways, once again delivering ahi in the mid-twenties, which indicates, at least, that the zero reading was probably a one-time event that had little to do with reality.
meanwhile, i took the machine back to dme this morning, and the tech agreed that the noise is not natural, but it may take him a few days to replace the device, which i am now told is indeed a loaner, not a replacement for the former s9. he says also that the s9's are in short supply as resmed is coming out with a new generation, not yet widely available in this configuration. at any rate, it is dme policy, he says, to observe this machine for 3 weeks before a decision will be made re a new machine. in other words, i think he is saying that dme wants to make sure it's not me, but the machine, causing the problem,
all of this sounds a bit confusing, if not deceptive, but as long as i am only signed off for a "loaner," and as long as it functions ok, i am willing to wait a bit longer, and put up with the noise.
