( Manual Mode). Level your multicopter. Flip CH5 switch three times quickly between Position 1 and Position

Rotate the multicopter counter clockwise( or clockwise) three times. ENSURE that the GREEN LED remains ON
during this procedure. If it turns OFF, it means the aircraft is not horizontal. Adjust the position until the GREEN
LED is back ON and continue with the rotation and put the multicopter level again.
