F&P Icon slow to calculate AHI and leak rate

I have had the Icon since January and I'm happy with it. However in the last month or so it has been taking hours to calculate my overnight AHI and leak rate figures. it never did this when I first got it. I could look up the numbers for the previous night and find them immediately. In all other ways it seems to be working perfectly well. Any ideas?

Thanks

the Icon uses 12 noon - to - 12 noon for a sleep period, as a result you won't be able to see your numbers on the LCD screen for the last night's sleep session until the clock gets past 12:00 noon the following day. There is also a "time zone" setting in the clinical menu that must be set to the correct time zone "GMT Offset" for the system to work properly in terms of time. I noticed when we switched to DST recently that I had to go into my clincal menu and adjust the time zone offset from GMT (example: mountain time is -7 hours; mountain daylight saving time is -6 hours) to get the machine to display my numbers properly right at 12:00 noon. If you didn't know this before, the numbers you might have been looking on your LCD screen could have been for the night before last if you were looking at the screen before 12:00 noon. Hope this makes some sense - - it might seem a bit confusing at first, but just realize that if you want to check your numbers for the last night on the machine's screen you have to wait till after the clock hits 12:00 noon to see the correct info for the previous night.

Thanks. That explains it.
