○If encounter the following situations, please recalibrate the aircraft compass:
1. Before the flight to a new flight site;
2. When the aircraft status indicator shows that the compass has errors;
3. When the APP and the aircraft remind to calibrate the compass;
4. When the aircraft experiences severe shifting during hovering or flying.
○ Compass Calibration via APP:
1. Enter Calibration Mode:
After the aircraft is connected to the APP, tap the “...” button in the upper right corner of the APP
control interface (Pic. 42) to enter the “General Settings” menu (Pic. 43).
Then tap the " Compass Calibration " button.
When the APP pops up a prompt, check the current environment and keep away from metal
objects as prompted. Then tap the "Calibration" button (Pic.44).
In this case, when the status indicator on the rear arm of the aircraft flashes blue and red
alternately, the compass calibration mode starts. At this time, the APP interface displays as Pic.
45.
2. Compass Calibration
There are two steps for compass calibration.
Step 1: Horizontal Calibration
When the APP prompts to rotate the aircraft horizontally, place the aircraft horizontally in the hand,
then turn the aircraft horizontally until the status indicator on the rear arm of the aircraft changes to
an alternatively flashing red and green light, which means that the horizontal calibration is
successful.
