How to use the compass:
the compass must be held horizontally, let it rotate freely. On the dial W on behalf of the West, N north, E on behalf of the East, S represents the South. Pointer red is N pole, White is S pole. When using a compass, do not approach ferromagnetic objects, high-voltage wires, electromagnetic devices, etc. to avoid errors and reduce the sensitivity of the compass.
