For a safe take-off, make sure that the Aircraft Status Indicators blink green slowly (using RTK* or
GNSS for positioning).
●
Spinning propellers can be dangerous. Stay away from spinning propellers and motors. DO NOT start the
motors in confined spaces or when there are people nearby.
●
Always keep your hands on the remote controller when the motors are spinning.
●
Stopping motors mid-flight: Perform the CSC to stop the motors. It can be enabled in a DJI app or
through DJI Mobile SDK (support coming soon, requires a selection in the third-party app). Only stop
motors mid-flight in emergency situations when doing so can reduce the risk of damage or injury.

Hover Accuracy Range
RTK enabled and functioning properly:
Vertical: ±0.1 m; Horizontal: ±0.1 m
RTK disabled:
Vertical: ±0.1 m (with vision positioning); ±0.5 m (with GNSS positioning)
Horizontal: ±0.3 m (with vision positioning); ±1.5 m (with GNSS positioning)
Image Position Offset
The position of the camera center is relative to the phase center of the onboard D-RTK antenna
under the aircraft body’s axis: (36, 0, and 192 mm) already applied to the image coordinates in
Exif data. The positive x, y, and z axes of the aircraft body point to the forward, rightward, and
downward of the aircraft, respectively.
