4 flashing green, then rapid red

[Sumolounge]

Hi. I am new to the forum and hobby. I have flown about 4 times now, but somehow can't get rid of the rapid red flashes after a series of 4 green flashes. Home point has been successfully set with rapid green, and the quad is flying nicely.
Does anyone know what 4 green followed by rapid red sequence means? Can't find it in the manual. The hardware is the following:

Phantom 2
H3-3d gimbal
Go pro black
Fpv

Can it be that it needs recalibration?

Thanks for your help and an awesome forum

Interesting, and makes sense since there is an airport about 5km away. Funny thing is that I am flying at a dedicated rc plane field (created by government). How do you know? Can you refer to the documentation?

Thanks

Great, thanks!
I guess they don't mention the indicator in their video. Where is this described? ( just for reference)
Anyway, thanks for the really quick response...
