REMOTE STOPPED PAIRING is reciever damaged?

REmote stopped pairing. I got the symbol on remote, when I turned on vesc power, for a moment, then it stopped.

I went thru motor startup again, and set up the remote. It doesnt pair, when I try on remote. There is no led lit on reciever. Is there supposed to be, I forget? If I remember correctly, there is one.

I ordered another, just in case.
