Turn the remote control over, and you can see the sticker on the back side, there is this marking to the left above. The whole thing is the transmitter that is directly installed in the remote control, and in 1B it is much weaker. The situation with the Mavic Mini is absolutely identical, only in Mavic Mini also has a weak signal transmitter in the drone itself, they have different boards for FCC and CE. With
Mavic 2, the situation is much simpler, the difference is in the remotes. Therefore, there is no point in redoing with the Ocusinc 2.0 system since it sends a signal for 12 km and more, it is already 100% verified, but only if your remote control 1A. Good luck, and I hope that you are lucky ... with the remote control.
