5. Maintenance

5.1 Cleaning the Trackball

If you experience issues such as stickiness, slowness, or scrolling problems with your trackball mouse, it likely needs cleaning. Follow these steps to clean and lubricate your trackball for optimal functionality:

1. Remove the trackball from its socket using the eject button on the bottom of the trackball frame.
2. Clean the trackball and the trackball frame with a damp cloth or rubbing alcohol. Allow them to dry completely.
3. Lightly lubricate the trackball with a non-acidic lotion. An oil-based lotion like Vaseline is recommended for best results. Evenly rub a pea-sized amount of lotion into the palms of your hands and roll the trackball across the lotion until it is evenly lubricated.
4. Gently push the trackball back into the socket. If it feels slightly sticky, roll it around in the socket until it moves freely.

6. Troubleshooting

If you encounter issues with your Kensington TB450 Trackball Mouse, consider the following:

• Connectivity Issues: Ensure the mouse is turned on and the correct channel (2.4GHz, Bluetooth 1, or Bluetooth 2) is selected. For Bluetooth, verify your device's Bluetooth is enabled and the mouse is paired. For 2.4GHz, try plugging the USB receiver into a different port.
• Cursor Movement Problems (Sticky, Slow, Erratic): This is often due to dirt or debris on the trackball or inside the socket. Refer to Section 5.1 for detailed cleaning instructions.
• Battery Life: If the mouse is unresponsive, the battery may be low. Replace the AA battery. The mouse offers up to 18 months with 2.4GHz and 15 months with Bluetooth.
• DPI Sensitivity: If the cursor speed is not as desired, adjust the DPI setting using the DPI switch button on the underside of the mouse.
