4. Keep the disk surface and lens clean, do not wipe with dirty cloth or hands
5. It should be closed when not in use, and should not be placed close to ferromagnetic substances to avoid loss of magnetism

The method used by the compass:
The compass must be held horizontally so that it can rotate freely. The w on the dial stands for west, N for north, E for east, and S for south. The red one on the pointer is the N pole, and the white one is the S pole. When using the compass, do not get close to ferromagnetic objects, high-voltage lines and electromagnetic devices, so as not to cause errors and reduce the sensitivity of the compass.
