Appendix B. Cleaning the mouse

This appendix provides instructions on how to clean your mouse. The procedure will be different depending on which type of mouse you have.

Cleaning an optical mouse

If you experience some problems with your optical mouse, check the following:

1.Unplug the mouse from the computer.

2.Turn the mouse over and look carefully at the lens area.

a.If there is a smudge on the lens, gently clean the area with a plain cotton-tipped swab.

b.If there is some debris in the lens, gently blow the debris away from the area.

3.Check the surface on which you are using the mouse. If you have a very intricate picture or pattern beneath the mouse it is difficult for the digital signal processor (DSP) to determine changes in the mouse position.
