The button will blink red when the aircraft is ready to link. Switch on the remote controller, turn the gimbal dial to the far left, and toggle the S2 switch back and forth quickly for at least three times. You will hear a pulsating beep sound when the remote controller is trying to link to the aircraft. The remote controller will stop beeping and the Link Button on the aircraft will turn solid green if linking is successful.
