-In an open environment, there is no occlusion, so as not to affect the search for satellite signals.
-The wind is less than 5 (
≤
8m/s).
-There is no strong magnetic field around, such as high-voltage lines, magnetite, etc., so as not to affect the
normal operation of the magnetic compass.
Do not calibrate in areas with strong magnetic or large blocks of metal, such as high voltage lines,
magnetic mines, parking lots, and buildings near steels.
Do not carry magnetic substances with your body during calibration, such as mobile phones
If the compass is calibrated indoors, remember to recalibrate when using it outdoors to prevent the
magnetic field difference between the two areas and cause abnormal flight data.
The position of the Earth's magnetic field is different. Please recalibrate the compass when replacing
a remote area.

-Make sure that the drone battery, remote control battery, and ground station (Android phone) are fully
charged.
-Make sure the drone battery is fixed.
-Ensure that the components are tightly fastened and that all screws are not loose.
-Make sure all connections are correct.
-Make sure that the propellers are not damaged, securely mounted, in the right direction, and that it works
correctly. All arms and propellers are fully deployed and the arm sleeve is locked.

Compass calibration must be performed before first use, otherwise the system may not work properly, which
may affect flight safety.
Calibration Steps:
The remote control E switch continuously dials 7-8 times or clicks the magnetic calibration command in
the ground station software. The LED indicator turns green and enters the horizontal calibration phase, as
shown below:
