Out of the Box???Normally constant beeping is an indication of failed firmware update and requires reloading.. Since its new out of the box call the support for p3 and they can better guide you.
On which page on the manual is the constant beeping mentioned?Out of the Box???
Read and study the manual
Do a firmware upgrade, and IMU Calibration and a Gimbal calibration and a control stick calibration.
If all of those succeed, and you still have the constant beeping , then call DJI support.
It is not in the manual, but there are various things a person needs to know from the manual that could be of help in diagnosing and determining the cause of problems or maybe avoiding problems. At least that has been the case for this ol' dog.On which page on the manual is the constant beeping mentioned?
I looked for it but did not find it.
