Maintenance
Cleaning the Keyboard

Cleaning the Trackball Mouse
- Disconnect the mouse from your computer.

- Wipe the trackball with a soft, dry cloth.
- Clean the inside cavity of the mouse, especially the optical sensor and support points, with a cotton swab or compressed air.

Troubleshooting
Keyboard or Mouse Not Responding
- Check Connection: Ensure the USB connector is securely plugged into your computer's USB port.
- Try a Different Port: Plug the devices into another USB-A or USB-C port on your computer.
- Restart Computer: Sometimes a simple restart can resolve connectivity issues.
- Test on Another Computer: If possible, test the keyboard and mouse on a different computer to determine if the issue is with the devices or your computer.
Trackball Movement is Erratic or Sticky
