The precautions for using the Xiaomi Wireless Mouse Lite 2 are as follows:
1. Maintain a flat surface on your desk and consider using a mouse pad, preferably one with a fabric surface, for optimal performance;
2. Do not use the mouse on transparent glass or high-gloss mirror surfaces, as these can affect tracking accuracy;
3. Keep the mouse clean, and promptly remove any dust or debris from the lens area on the bottom;
4. Avoid exposing the mouse to liquids, as spills can cause issues with feel and electrical performance;
5. It is recommended to connect the mouse directly to the computer's USB port. Using USB hubs or adapters can cause lag or connectivity issues.
