Is there a complete list of Varia RLT510 error codes anywhere?

I have a Varia RLT510 and today I got Varia error code 0:FC displayed on my Edge 130 but I can't find any information about that error code or any error codes. It's not helpful to display an error code without any information about what is means and what needs to be done to correct it. My Varia has been working fine,  I do get a few false alarms but usually in exactly the same places along my usual ride, some of them I can associate with particular road signs or large mailboxes. But on the last couple of rides it has been acting up, giving sudden bunches of false alarms, and today I got the 0:FC error code. I checked and the software is up to date.
