Alarm sounds and red light flashes when I power up the controller.  Can't find any info on that.  Overall Status:  Says "Remote Controller not calibrated".
How do I calibrate sticks in remote controller?

Maximum altitude reached..

Does it happen as soon as you power on the controller?
Do you have the Phantom on at the same time?

Yes as soon as it powers up.  Red light flashes and beeps.  P4 not turned on yet.

The User Manual for the P3 4K describes that behavior. Search for 'Remote Controller Status LED' in your Phantom 4 User Manual.

I have the same problem, so I enter into remote controller calibration on the app and I follow the instructions then, the alarm stops, but the problem starts again when I turn on the controller again.

Did you ensure that the sticks were not moved while power cycling the RC? The RC will believe it lost calibration if they are not center upon startup.

I'm having the same problem.  Red light blinking and beeping at startup, abnormal status, RC needs calibrated every time it powers up.  Sticks are not touched, they're certainly not touched EVERY time I start it and it's beeping to high heaven every time until I calibrate the RC.  Don't see what the core problem could be here.  Anyone?  Thanks.
