Storage in a safe. Interference in Red zone

[ShonVon]

Hello. Acted stupidly. Left the drone for the night in a metal safe. Magnetized compass. Nothing is working now. Compass error and atti mode always. What should I do? Change the compass or demagnetize the compass or give the drone for repair under warranty?

Cfixer gets recommended a lot, seems to do the trick.

Thank. Yes, this device has helped me. I read a lot of threads in different forums and this device really works. In the service, I demagnetized my compass and the problem disappeared.
