             A low battery level warning is indicated by the Aircraft Status Indicators blinking red
              slowly or rapidly during flight.
             Watch our video tutorials for more flight information.




Flight Status Indicator

The Spark has Front LEDs and Aircraft Status Indicators. The Front LEDs show the orientation of the
aircraft. The Front LEDs glow solid red when the aircraft is turned on to indicate the front (or nose)
of the aircraft (the Front LED can be turned off in the DJI GO 4 app). The Aircraft Status Indicator
communicates the system status of the flight controller. Refer to the table below for more
information about the Aircraft Status Indicator.




                                                                                                    15


Calibrating the Compass

Only calibrate the compass when the DJI GO 4 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 4 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. 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.
                                                                                                  16


3. Hold the aircraft vertically, with nose pointing downward, and rotate it 360 degrees around
   the center axis.
4. Re-calibrate the aircraft if the aircraft status indicators blink red.


       If the Aircraft Status Indicator blinks red and yellow after the calibration procedure, move
       your aircraft to a different location and try again.
           DO NOT calibrate the compass near metal objects such as a metal bridge, cars, and
            scaffolding.
           If the aircraft status indicator is blinking red and yellow alternately after placing the
            aircraft on the ground, the compass has detected magnetic interference. Change
            your location.
