5. Maintenance
Proper care and maintenance will extend the life of your mouse.
- Cleaning: Regularly clean the mouse surface with a soft, dry, lint-free cloth. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaner. Avoid spraying liquids directly onto the mouse.
- Optical Sensor: Ensure the optical sensor on the underside of the mouse remains clean and free of dust or debris for accurate tracking. Use a cotton swab to gently clean the sensor area if necessary.
- Cable Care: Avoid bending or twisting the mouse cable excessively, as this can damage the internal wires. Store the cable neatly when not in use.
- Operating Environment: Use the mouse on a clean, flat surface. Avoid extreme temperatures, high humidity, or direct sunlight.
