Operating the Mouse

Basic Mouse Functions

• Left Button: Primary click for selecting items, opening files, etc.
• Right Button: Secondary click for context menus and additional options.
• Scroll Wheel: Scroll up or down through documents and web pages. Can also be pressed as a middle button for specific functions (e.g., opening links in new tabs).

Using the Fingerprint Reader

• Login/Authentication: When prompted for authentication (e.g., Windows login, secure websites, or applications configured with the SDK), gently place your enrolled finger on the fingerprint sensor. The system will verify your identity.
• Best Practices: Ensure your finger is clean and dry. Place your finger flat on the sensor for optimal recognition.

Maintenance

• Cleaning the Mouse: Use a soft, slightly damp, lint-free cloth to wipe the exterior of the mouse. Avoid abrasive cleaners or solvents.
• Cleaning the Fingerprint Sensor: Gently wipe the sensor surface with a clean, dry, soft cloth. Do not use liquids or harsh chemicals on the sensor.
• Storage: Store the mouse in a clean, dry environment when not in use.
• Cable Care: Avoid sharp bends or excessive pulling on the USB cable to prevent damage.

Troubleshooting

Mouse Not Responding

• Check USB Connection: Ensure the USB cable is securely plugged into a working USB port on your computer.
• Try Another USB Port: Connect the mouse to a different USB port on your computer.
• Restart Computer: A system restart can often resolve connectivity issues.
• Test on Another Computer: If possible, test the mouse on another computer to determine if the issue is with the mouse or your system.

Fingerprint Reader Not Working

• Clean Sensor: Ensure the fingerprint sensor is clean and free of dirt or moisture.
• Re-enroll Fingerprint: If recognition is consistently failing, try deleting and re-enrolling your fingerprints in Windows Hello settings.
• Check Drivers: Verify that the latest drivers for the fingerprint reader are installed. Check Windows Device Manager for any error indicators.
• Windows Hello Settings: Confirm that Windows Hello Fingerprint is enabled and configured correctly in your system settings.

Erratic Cursor Movement
