FAQ1
How to Clean Your Trackball Mouse?
If your trackball mouse cursor is sticking or jumping around on your screen,
or it's just not moving smoothly, you can clean it for better performance.
(1) Push the trackball from the bottom of the mouse.
(2) Use a humid cloth to clean the trackball, the surface of the inner trackball
housing and the sensor. Then use a cotton swab to clean the dust on three
white rollers.
Note:
Don't clean the mouse and trackball with alcohol or wet wipes containing
alcohol.
When you clean near the optical sensor, please wipe it carefully to avoid
damaging it.
