Sorry if this has been answered already, but I could not find what I am experiencing. I bought a used Phantom 3 standard and everything was fine for a few flights. Now I have an issue I cannot solve. When I turn on my controller it will constantly beep and won't stop. If I turn it off and back on the beeping resumes. It is a BEEP-BEEP-BEEP like an alarm with no varing tempo (No BEEP-PAUSE-BEEP_BEEP-PAUSE, etc.). I talked to a friend and he suggested the throttle was in the down position (not the case). I replaced the remote controller battery (no change). I tried to check the connections on the board, all seem fully engagd. Any ideas would be appreciated.

Hello there Z. I am sorry for the trouble this has caused and thank you for reaching out. Can you please try to calibrate the remote controller of your DJI Phantom 3 Standard to see if the issue will still persist? I will post a DJI Tutorial video on how to calibrate the said remote controller of the said DJI Drone. Thank you.

That seems to have done the trick! I was not able to get to the calibration screen for some time, glitchy app I guess, but when I was it fixed it right away. Thank you!!!

I have the same beeping issue phantom 4 but at the RC calibration screen every time I press start a warning window pops up about returning sticks to midpoint before clicking “start” so click “OK” and back to start screen press start and window comes up again!!
How do I progress the RC calibration?
