[size=14.6667px]Remote control status light is blinking red and beeping. Have tried RC calibration but never can get it started. When I touch 'Calibrate' and expect to see 2 lines of instructions for moving sticks and wheel, instead I get a 'Warning' Box saying "Return sticks to midpoints before clicking 'Start' button. During calibration, follow all prompts. Not doing so may lead to calibration failure." Followed by choice of 'Cancel' or 'OK'. Click 'OK' but can't get out of the Warning Box --> Start loop and it never allows me to move the sticks or the wheel. Suggestions???

What drone are you using?
If it is Phantom 3 series, we got a tutorial video for calibrating the RC, have a quick glance if you need:
Had you rebooted the controller after you got the warning box which kept on the screen all the time?
