Hi, I'm unable to calibrate my Phantom 4 Pro V2.0 remote controller.  I can only take off and land using the beginner's mode and precision Return Home setting because I cannot use the controller joysticks to fly forward or backwards or turn the aircraft left or right, including the camera gimbal. The red button stays on and beeps non-stop. This is extremely frustrating.  I'll really appreciate your assistance with this problem, thank you.
