6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your Acer M115 mouse.
- 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 harsh chemicals or abrasive materials.
- Sensor Care: Keep the optical sensor on the bottom of the mouse clean and free from dust or debris to ensure accurate tracking.
- Cable Management: Avoid sharply bending or twisting the USB cable to prevent internal damage.
- Storage: When not in use, store the mouse in a clean, dry environment away from extreme temperatures.

7. Troubleshooting
If you encounter issues with your Acer M115 mouse, please refer to the following common solutions:
- Mouse Not Responding:
- Ensure the USB cable is securely plugged into a working USB port on your computer.
- Try plugging the mouse into a different USB port.
- Restart your computer.
- Test the mouse on another computer to determine if the issue is with the mouse or your system.
- Erratic Cursor Movement:
- Clean the optical sensor on the bottom of the mouse with a soft, dry cloth.
- Ensure you are using the mouse on a clean, non-reflective, and uniform surface (a mouse pad is recommended).
- Check for any software conflicts or outdated drivers (though typically plug-and-play, system updates can sometimes affect peripherals).
- DPI Button Not Changing Sensitivity:
- Ensure you are pressing the correct DPI button.
- Verify that the mouse is properly connected and recognized by your system.
- Lighting Not Working:
- Confirm the mouse is properly connected to your computer.
- The lighting is automatic and not user-configurable. If the mouse functions but the light does not, there might be a hardware issue with the LEDs.
8. User Tips
Enhance your experience with these practical tips:
- DPI Customization: Experiment with the different DPI settings (800/1600/2400/3200) to find the sensitivity that best suits your tasks. Lower DPI is often preferred for precision work, while higher DPI can be beneficial for faster movements in gaming.
- Ergonomics: The mouse is designed for a comfortable, right-hand grip. Ensure your hand rests naturally on the mouse to reduce strain during prolonged use.
- Surface Choice: While the optical sensor is versatile, using a good quality mouse pad can significantly improve tracking accuracy and overall performance.
- Button Programming: Although the product description mentions "Macro Definition Programming," specific software for this is not provided in the basic package. For advanced button customization, you may need to explore third-party mouse customization software compatible with generic USB mice, or check Acer's official support website for any dedicated utilities.
