I am getting the above error on my p4? It says "vision system recalibration required"   Can someone tell what I am supposed to recalibrate?  I can be flying and it just pops up and doesn't go away.  Any help will be appreciated.

OK, using DJI Assistant downloaded to a PC. Install application and usb driver (it's all there), if not already done. Connect drone to PC with USB cable and power up. Run DJI Assistant, select P4 device , when it opens up there is an option down the left hand menu that allows you to calibrate the cameras (sensors). Takes a couple of minutes to do and a steady hand

Thanks for the info. Any reason why I would have do this. The drone only has 10 hours flight time and since I am a newby it has really been babied?

Thanks

The reason I suppose is that they just need calibrated, like the IMU, compass,  gimbal & RC controls. If they've not been done since you got the aircraft then would be good working practice to calibrate all.

I saw that message for the first time today after about 80 flights.  Shutting the Phantom down and restarting cleared it.

I'm sorry but that is ridiculous to expect people to do that. I'm 76 live my life in a wheel chair and my hands shake much too much to try that. Surely it's a procedure that should be done in the workshop before being released to the general public. {:4_177:}

I have same problem but I can not complete the procedure on my PC, what can be the reason?

on my Imac, calibration won't start.... Calibration screen remains blank. Is the 27' screen to big? (5120 x 2880)

27 INCH 5K IMAC looks not supported. Tried with smaller screen and was easily able to calibrate.
