Error Code on ResMed AutoSet II

Hello,

I work up this morning with a slight smell of something burning. It was faint but I could pick it up. At first I thought someone might have been cooking something in the Kitchen, as there has been a few times, that the smell of burnt toast will get into my Cpap very fast.
So I went to turn the machine off and it wouldn't turn off, and there was a error code. I unpulled it and plugged it back in and it worked fine and the smell was gone. I called my DME and they are coming to replace it.
Because I was just waking up, I didn't pay attention to the error that came up on the screen. Do anyone know if there is a way to access any errors that came up on the machine after the fact. Would it possibly show up on the data card if I downloaded it.
