About The Mouse And Keyboard

To use an optical mouse (USB)

If you are using an optical mouse, use an appropriate surface to ensure good
mouse tracking. A good mouse surface requires a certain amount of detail or
texture to enable mouse tracking.
❑Use surfaces such as plain paper, card stock, or fabric that do not have a
lot of repetitive patterning. Avoid surfaces such as mirrors, smooth
glass, or magazines. To avoid possible damage to easily-scratched
surfaces, use a mouse pad.
❑Avoid surfaces that may damage or soil your optical mouse. Dirt or
damage may cause the mouse to malfunction.
❑If the cursor is not moving properly, try using the mouse on another
mousing surface or using a mouse pad.

3Remove the mouse ball cover on the back of the mouse by turning
clockwise the ring that covers the mouse ball.
4Turn the mouse upright, and drop the mouse ball into your hand.
5Using a piece of tape, remove any dust or dirt on the mouse ball and
inside the mouse ball socket.
6Return the mouse ball to the socket, and replace the mouse ball cover.
