2. Adjusting Sensitivity (DPI)
The G102's gaming-grade sensor offers adjustable sensitivity from 200 to 8,000 DPI (Dots Per Inch). You can set up to 5 different DPI levels and cycle through them using a dedicated button, which is useful for games requiring varying levels of control (e.g., precise aiming vs. fast movement).

- Animations: Choose dynamic lighting animations.
- Screen Sampler: Synchronize your mouse lighting with the colors on your screen.
- Audio Visualizer: Make your mouse flash colors to the beat of your music, movies, or games.

4. Onboard Memory
The G102 features onboard memory, allowing you to save your custom settings directly to the mouse. This means you can take your personalized configurations with you and use them on other computers without needing to install Logitech G Hub software or re-configure your settings. Simply plug and play.

Maintenance
To ensure the longevity and optimal performance of your Logitech G102 mouse, follow these simple maintenance tips:
- Cleaning: Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution to wipe down the mouse surface. Avoid harsh chemicals or abrasive materials.
- Sensor Care: Keep the optical sensor on the underside of the mouse clean from dust and debris. Use a can of compressed air to gently blow away any particles. Do not touch the sensor directly.
- Cable Management: Avoid sharp bends or excessive pulling on the mouse cable to prevent damage.
Troubleshooting
If you encounter issues with your Logitech G102 mouse, try the following steps:
- Mouse Not Responding:
- Ensure the USB cable is securely plugged into your computer.
- Try plugging the mouse into a different USB port.
- Restart your computer. - DPI or RGB Settings Not Applying:
- Make sure Logitech G Hub software is running and updated to the latest version.
- Check if the mouse is in 'Onboard Memory Mode' if you expect software settings to apply. If so, ensure your profile is saved to the onboard memory.
- Try creating a new profile in G Hub and applying it. - Inconsistent Tracking:
- Clean the optical sensor on the bottom of the mouse.
- Ensure you are using the mouse on a clean, uniform surface (a mouse pad is recommended).
- Check for any software conflicts or background applications that might interfere with mouse performance. - Buttons Not Working:
- Verify button assignments in Logitech G Hub. Ensure no conflicting assignments are present.
