Hey everyone I have a recently repaired M210 (bad battery lock where it snaps in) and I am in the hotel just running a bunch of tests and calibrations and when I power on the motors (no props) I get an error message that is a big red circle in the middle of the screen that says TOP (image attached). I am wondering if its warning me there is a ceiling to close or if its an error message for something else? I'll be testing outside tomorrow but wanted to see if anyone has run into this tonight......

Take Off Prohibited?

It looks like it was detecting the ceiling in the hotel room. Wouldn't have stopped flight but just never seen that error before.
