I posted this on the "old" Legend board as well.
It seems as though there have been a lot of Info Center related questions lately. I dug this up in the huge amount of paperwork that accompanied the purchase of my Legend. It contains what I would call, "unpublished" operating instructions/features of the Info Center.
Somebody's "Distance-to-Empty = N/A" issue is addressed as well. You just have to read the document carefully.
I hope this helps some of you get your Info Center working and displaying meaningful numbers. It should give you a better understanding of how the Info Center works.
Sorry for the large file size.
