Calibrating the Compass
Only calibrate the compass when the DJI GO app or the status indicator prompt you to do so. Observe 
the following rules when calibrating your compass:
 DO NOT calibrate your compass where there is a chance of strong magnetic interference, such 
as magnetite, parking structures, and steel reinforcements underground.
 DO NOT carry ferromagnetic materials with you during calibration such as cellular phones. 
 The DJI GO app will prompt you to resolve the compass issue if the compass is affected by 
strong interference after calibration is complete. Follow the prompted instructions to resolve the 
compass issue.
Calibration Procedures
Choose an open area to carry out the following procedures. 
1. Ensure that the compass is calibrated. If you did not calibrate the compass as part of your pre-flight 
preparations, or if you have moved to a new location since the last calibration, tap the Aircraft Status 
Bar in the app and select “Calibrate”, then follow the on-screen instructions.
2. Hold the aircraft horizontally and rotate 360 degrees. The Aircraft Status Indicators will display a solid 
green light.
