Monitor screen
Do not use abrasive cleaners when cleaning the surface of the monitor screen.
The screen surface is easily scratched, so avoid touching it with pens, pencil
points, and erasers.
To clean the screen surface, wipe it gently with a soft, dry cloth, or blow on the
screen to remove grit and other loose particles. Then use a soft cloth moistened
with a nonabrasive liquid glass cleaner.
Mouse
If the pointer on the screen does not move smoothly with the mouse, you
might need to clean the mouse.
To clean your mouse:
1. Turn off the computer.
2. Disconnect the mouse cable from the computer.
3. Turn the mouse upside down. Unlock the retainer on the bottom of the
mouse by moving it in the direction indicated by the arrow on the retainer.
4. Turn the mouse right-side up, and the retainer and ball will drop out.
5. Wash the ball in warm, soapy water and dry it well.
6. Using a damp cloth, wipe the outside of the mouse and the retainer. Be
sure to wipe the rollers inside the mouse.
7. Insert the ball and retainer. Lock the retainer by moving it in the opposite
direction of the arrow.
8. Reconnect the mouse cable to the computer.
