I have a Phantom Pro 4 with the Screenless controller. I havent used the Drone in a few months due to weather and lockdown restrictions.

Ive come to start it up today to get the Drone calibrated and tested in readiness for some up coming work. The controller however seems to constantly beep and have a flashing RED led on the front.

Checks and actions completed
1. Fully charged the controller
2. Used a fully charged Battery on the drone
3. Performed a hard reset on the controller using C1, C2 and record buttons (flashing Blue LED and beeps), and then linked to the Drone and the beeping continues with RED LED.

What would be the next steps to stop the beeping and get the control into a fully functioning state?

Hello there. I am sorry for the trouble this has caused and thank you for reaching out. Can you please try to calibrate your DJI Phantom 4 Pro's remote controller then try to relink the said DJI drone to it's remote controller. Thank you.

Thank you for the support, after resetting and calibrating the RC, resetting and re-linking the Drone the beeping stopped and the Drone is active and working again.
