of dust or lint around the mouse ball and tracking mechanism. Periodically, however, the
mouse ball must be cleaned. Use the following procedure to clean the mouse.
1. Unplug the mouse from the system.
2. Turn the mouse upside down and locate the mouse ball cover (see Figure Section
4-2).
Turn the ball cover counterclockwise and remove the cover.
