6. Entretien
6.1 Nettoyage de la trackball
To ensure smooth and accurate tracking, regularly clean the trackball and the three white rollers inside its housing. After a period of use, dust and debris can accumulate, affecting performance. To clean:
- Gently push the trackball from the bottom opening to remove it.
- Use a soft, lint-free cloth to wipe the trackball and the three internal rollers.
- Réinsérez la boule de commande dans son logement.
Note: If the trackball does not run smoothly, especially when the computer is just started or a large application is running, it may indicate a need for cleaning.

7. Dépannage
7.1 Getting Used to the Trackball Mouse
For first-time users, adapting to the thumb-controlled trackball may require a learning curve. It is recommended to experiment with different hand positions to find what is most comfortable. Many users find that after 1-2 weeks of consistent use, the trackball mouse significantly reduces wrist pressure and pain compared to traditional mice.
7.2 Trackball Not Moving Smoothly
If the trackball's movement becomes sluggish or imprecise, it is likely due to accumulated dust or debris. Refer to Section 6.1 for instructions on how to clean the trackball and internal rollers.
