Maintenance
Regular cleaning of your trackball mouse ensures optimal performance and longevity.
Cleaning the Trackball
- Remove the Trackball: Gently push the trackball from the underside of the mouse or use a blunt object to pop it out from the top.
- Clean the Ball: Wipe the trackball with a soft, lint-free cloth. If necessary, dampen the cloth slightly with water or a mild, non-abrasive cleaner.
- Clean the Sensor Area: Inside the trackball cavity, you will see the optical sensor and small support points. Use a dry cotton swab or compressed air to remove any dust or debris that may have accumulated around these areas. Avoid touching the optical sensor directly with your fingers.
- Reinsert the Trackball: Place the clean trackball back into its cavity, ensuring it sits securely.
Note: Do not use harsh chemicals or abrasive materials, as these can damage the mouse surface or internal components.
