Machine time set wrong

[me50]

I think if you wait until after noon real time - your machine will show 12:45 or 1:00 or later - you will be able to set the clock back. The new day starts at noon, so as long as you don't record data after that you can set the clock back to any time after noon.

My ResMed loses time - 3-4 minutes per month - so I haven't had to set my clock back. But I'm pretty sure waiting past noon will work.

Well, just got back from the DME and they were able to change the minutes but its still an hour ahead and they could not change that. They did not want to mess with it any further until my compliance period is over.

Hmmm.....concerns me that they figured out how to change the minutes but not the hour. If they change minutes, they can change the hour by turning the knob back to the hour position. That is how I did it if I am not mistaken.

I would give you more help but you said you haven't met your compliance yet so I presume you want to leave things alone for now.

You should be able to go back in time as long as there's no data there.

Example:

Turn the blower off at 8 AM. Wait until 9 AM. At that point, you should be able to set the clock back to 8:01 AM.

You don't need to unplug or do any such stuff.

This is correct. The machine will let you set the time back, but not if there is data in that time period. If you try to change it in the morning when you first wake, it will not do it - but later in the day it should be fine. I did this to mine when it was about a week old too.
