Using the USB Optical Mouse
The USB optical mouse is available with select models. It provides
the same functions as the scroll mouse and wireless wheel mouse
except it uses an optical sensor instead of a mechanical ball to
determine the position of the cursor on the screen. The surface on
which you use the optical mouse plays an important role in tracking
the cursor. When using the optical mouse:
■
Use a mousepad or a white sheet of paper underneath your
mouse. Using it on a glass or see-through surface will inhibit the
ability of the sensor to track the cursor.
■
Avoid using the mouse on a reflective surface such as a mirror or
shiny metal disk. This may cause tracking problems.
■
Some wood grains and grooved surfaces may also cause tracking
problems.

Refer to the “Solving Minor Problems” section in this guide if
your optical mouse does not function properly.
