[Equipment] TIME/DATE - ResMed AirSense AutoSet 10

[Hydrangea]

Ok! I understand it now!

You can only push it back to noon. So after midnight, I pushed it back to noon, and then the machine's tomorrow-date was finally today. Yay. And at noon today, I'll push it back to noon, and hopefully it'll be all correct.

And I will never mess with daylight savings again!!

From the clinician's manual:

If you set a new date that occurs in the past then an error message is
displayed. Before this change can be made, erase the compliance data
available under the Configuration menu.

Remember to save the data to the software of your choice (ResScan, OSCAR, Sleepyhead, etc.) before erasing data. I also save the contents of my SD card to a folder. When I changed my date in this manner, I lost all of the the detail data that I had not already transferred but my A10 copied all of the summary data back on the card.

I stumbled on this thread after I too became trapped in this bizarre spider web of Resmed code. The only way I can defend the way it is coded is if they ran out of firmware space, because it is very unprofessional. Granted, we take on more responsibility using the Clinician's Menu, BUT this is a crazy bug. It is one more indication to me that Resmed is ignoring the data from the cell tower that would give it date and time so I couldn't have set a future data accidentally in the first place. (If there is no modem connection, it could fallback to another approach like asking "are you sure because it will overwrite data already recorded for that date").

I backed up the SD card and then left it OUT of the machine when I used ericxob's suggestion from the manual to clear the data. I told it to erase and then I was able to change the date back. Then I inserted the card and it appears it just picked up where it left off. Whew....
