CCX flashing red lights

[mint peak]

My CCX flashes red lights, 2 top then 2 bottom blinks. Not sure what this means. I'm using it to type, but haven't tried any chords yet.
Edit: I reinserted the device, and it's flashing red but a different pattern. Is there a page where these are described?

Hi there! Is the device otherwise functioning properly?

The flashing lights are normal.
