Hours of Use data problems with myAir

For weeks I have been trying to find out why my Hours of Use reported to myAir is usually 5-6 hours when my actual use is between 7 and 8 hours ... something just wasn't right!

Finally figured it out ... a forum post (not sure which forum, though) recommended checking the date/time on my AirSense10 if erroneous data was being recorded. Had to find my "cheat sheet" for getting to the technician's setup ... discovered that although the date was correct, the time was way off! When I checked at around 10pm, the time on my machine was "8" am ... no wonder I have been getting wonky readings!! The data is transmitted each day at noon, and reset after transmission. So what has been happening is that my machine was reporting data after around four hours of sleep ... so the remainder of my sleep was simply dismissed ...

Since I changed the time on my machine to the correct 24-hour time, myAir has been reporting the correct Hours of Use data. Hurray! My data is now correct, and my nightly score is almost always near 100!

Hi tback

I hadn't realised it would dismiss the balance.

Most CPAP suppliers don't seem to bother setting the time correctly.

Both times I've accepted a machine from a local CPAP sleep centre the clock was several hours out.

You'd think it was an essential part of their job.

I don't have any online existence that I am aware of but don't they have the capacity to tweak your settings?

If they do why can't they synchronize the clock while they are at it?
