1 Calibrating the Compass
IMPORTANT: Make sure to calibrate the compass in every new flight location. The compass is very sensitive to
electromagnetic interference, which can cause abnormal compass data leading to poor flight performance or even
flight failure. Regular calibration is required for optimum performance.
(1) DO NOT calibrate your compass where there is a chance of strong magnetic interference, such as
magnetite, parking structures, and steel reinforcements underground.
(2) DO NOT carry ferromagnetic materials with you during calibration such as keys or cellular phones.
(3) DO NOT calibrate beside massive metal objects.
1.1 Calibration Procedures
Choose an open space to carry out the following procedures. Watch the Phantom 2 Vision+ quick start video for
more details.

If compass calibration is needed before flight, a prompt will appear on the DJI VISON App’s camera
page. It will disappear after successful calibration.
1.2 When to Recalibrate
1. When compass data is abnormal, the rear LED flight indicator will blink red and yellow.
2. Flying in different location to last flight.
3. Mechanical structure of the Phantom has changed, i.e. changed mounting position of the compass.
4. Severe drifting occurs in flight, i.e. Phantom does not fly in straight lines.
