Cleaning the Mouse
Mechanical mouse
The mouse operation depends on the degree of smoothness of the internal ball rotation. To
keep the mouse ball clean, use the mouse in a place with little dust.
1.
Prepare cold or lukewarm water, neutral detergent, alcohol, two dry soft
clothes, and cotton swabs.
2.
Power off the system.
The POWER/SLEEP lamp is unlit.
3.
Turn the mouse upside down, and rotate the mouse ball cover counter
clockwise to remove it.
4.
Take out the ball from the mouse. Cover the bottom of the mouse with your
hand, and turn your hand holding the mouse (the mouse is on your palm with
the button upward). The mouse ball is released onto your palm.
5.
Soak a soft cloth in neutral detergent that is diluted with cold or lukewarm
water, and squeeze it firmly.
6.
Rub off stains on the mouse ball. Softly wipe the mouse ball with the cloth
prepared in Step 5.
7.
Wipe the mouse ball with a dry soft cloth.
8.
Wipe three small rollers inside the mouse with a cotton swab soaked with
alcohol. Wipe stains slowly and carefully by rotating rollers with the tip of the
cotton swab.
9.
Blow out any dust from the mouse. Protect your eyes from the dust.
10.
Put the mouse ball back into the mouse.
11.
Place the mouse ball cover, and rotate it clockwise until it is locked.
Optical Mouse
An optical mouse is an advanced computer pointing device that uses a light-emitting
diode (LED), an optical sensor, and digital signal processing (DSP). Movements of the
mouse are detected by sensing changes in the reflected light, rather than by interpreting
the motion of a rolling sphere as with a mechanical mouse.
Tips for correct use
The optical mouse takes microscopic snapshots of the working surface at a rate of more
than 1,000 images per second. If the mouse is moved, the image changes. The smallest
irregularities in the surface can produce images that are sufficient for the sensor and
DSP to generate usable movement data.
Considering the way the optical mouse works:
■
Avoid mouse pads that are very glossy or highly reflective.
■
Avoid dark mouse pads.
■
Use your mouse on colors such as white, tan, or grey.
■
Use your mouse on surfaces with a flat, non-reflective finish.
