Notes:

2. To avoid the misalignment of the compass, please maintain a certain distance from iron mesh and objects with magnetic properties (such as high-voltage lines, generators, sound equipment, magnets, etc.)
3. Do not strike or pat the compass with your hand, which may affect the measurement accuracy.
4. Keep the shell and mirror surface clean, do not use dirty cloth or hands to wipe.
5. When not in use, store it in the box, and do not place it near magnetic materials to avoid losing its magnetism.
