4. Maintenance
4.1 Cleaning
To maintain optimal performance and hygiene, regularly clean your mouse. Use a soft, dry, lint-free cloth to wipe down the surface. For stubborn dirt or grime, a slightly damp cloth can be used, ensuring no moisture enters the internal components. The advanced surface materials are designed to combat heat, moisture build-up, and fingerprints.
4.2 Cable Care
Avoid sharp bends, kinks, or excessive pulling on the mouse cable to prevent internal wire damage. Proper cable management can significantly extend the lifespan of your mouse.
5. Troubleshooting
5.1 Mouse Not Responding
- Ensure the USB cable is securely connected to your computer's USB port.
- Try connecting the mouse to a different USB port on your computer.
- Restart your computer to refresh USB device detection.
- If using Logitech Gaming Software, ensure it is up to date and correctly configured.
5.2 Intermittent Clicking Issues
If the mouse buttons exhibit inconsistent or double-clicking behavior, this may indicate wear over time. While the G100s buttons are rated for an impressive 20 million clicks, extensive and prolonged use can eventually lead to such issues. Ensure your operating system drivers are updated. If the problem persists, refer to the warranty and support section for further assistance.
