10 Calibrating the Compass
IMPORTANT: Make sure to perform the Compass Calibration procedures prior to the first flight.
The compass is very sensitive to electromagnetic interference which causes abnormal compass data and leads
to poor flight performance or even flight failure. Regular calibration of the compass enables the compass to
perform at its optimal level.
10.1 Calibration Warnings
(1)
(2)
(3)
DO NOT calibrate your compass where there is a possibility for the existence of strong magnetic
interference such as magnetite, parking structures, and steel reinforcement underground.
DO NOT carry ferromagnetic materials with you during calibration such as keys or cellular phones.
Compass Calibration is very important; otherwise the flight control system will not work properly.
10.2 Calibration Procedures
Choose an open space to carry out the following procedures. Please watch the quick start video of the PHANTOM
2 VISION for more compass calibration details.

10.3 When Recalibration Is Required
(1) When Compass Data is abnormal, the LED flight indicator will blink alternating between red and yellow.
(2) Last compass calibration was performed at a completely different flying field/location.
(3) The mechanical structure of the aircraft has changed, i.e. changed mounting position of the compass.
(4) Evident drifting occurs in flight, i.e. the aircraft doesn’t fly in straight lines.
