■ Use your mouse on surfaces that reflect but also scatter the light, such a a white

sheet of drawing paper.

Note: If you experience erratic mouse behavior, test it on a

plain white sheet of paper.

Cleaning the Light-Emitting Diode (LED)

Turn the mouse over and inspect the light-emitting diode "LED" area to make sure it is

clean. In practice, an optical mouse does not have the issues with debris build-up that

the older, mechanical ball mice experience.

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

■ If there are some debris in the lens area, gently blow them away.

Cleaning the Soft Pads

Over time, dust may collect on the soft pads located on the bottom of the mouse.We

recommend you remove the dust on each softpad using a coin. You can also place the

mouse on a white sheet of paper, and run the mouse over it (apply soft pressure on the

mouse while doing so).

Note: Do not use a sharp instrument, it could damage the

soft pads.

Cleaning an Optical Disc Drive

A dust-accumulated tray or a dusty optical drive may cause the device not to read data

correctly.

To Clean an Optical Drive:

1. Power on the system.

The POWER/SLEEP lamp is lit.

2. Press the optical drive tray Open/Close button on the front of the optical drive.

The tray opens.

3. Hold the disc and take it out from the tray.

Note: Do not touch the signal side of the disc with your fin-

gers.
