Maintenance
To ensure optimal performance and longevity of your CHUWI Wireless Mouse S1:
- Cleaning: Use a soft, dry cloth to wipe the surface of the mouse. For stubborn dirt, slightly dampen the cloth with water or a mild cleaning solution. Avoid using harsh chemicals or abrasive materials.
- Sensor Maintenance: Periodically clean the optical sensor area at the bottom of the mouse with a cotton swab to prevent dust buildup, which can affect tracking performance.
- Storage: When not in use for extended periods, consider removing the AA battery to prevent potential leakage. Store the USB receiver in its designated slot within the mouse to prevent loss.
- Environmental Protection: The mouse features a splash-proof and dust-proof design, contributing to its durability. However, avoid exposing it to excessive moisture or dust.
Troubleshooting
If you encounter issues with your CHUWI Wireless Mouse S1, refer to the following common solutions:
- Mouse Not Responding:
- Ensure the AA battery is correctly installed and has sufficient charge. Replace the battery if necessary.

- Restart your computer.
- Erratic Cursor Movement:
- Clean the optical sensor at the bottom of the mouse.
- Ensure you are using the mouse on a suitable surface. Highly reflective or transparent surfaces may affect tracking. A mouse pad is recommended.
