The Forward, Backward, and Downward Vision Systems can be calibrated with DJI Assistant 2 and DJI GO 4. If there is an error with the Forward, Backward, or Downward Vision Systems, a prompt stating that auto calibration for the Vision System is required will pop up in the DJI GO 4 app. Follow the instructions in the DJI GO 4 app for calibration. It is recommended to calibrate the Forward, Backward, and Downward Vision Systems with DJI Assistant 2. If you don't have a computer at hand, calibrate them with the DJI GO app.
As per your second inquiry, the maximum altitude for Phantom 4 is 10m. The red light showing on the front led light on your aircraft indicates that you already reached the maximum limit. Please refer on the specs below.
"As per your second inquiry, the maximum altitude for Phantom 4 is 10m. The red light showing on the front led light on your aircraft indicates that you already reached the maximum limit. Please refer on the specs below."
This statement is at best incorrect. The limit of the visual positioning system is 10m above surface below. The altitude limit above take off point is 500m as set in the aircrafts firmware.
The front red LEDs are the navigation lights and are always illuminated unless you chose to extinguish them.
