Cleaning the 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 server.
The POWER/SLEEP lamp goes off.
3.
Turn the mouse upside down, and rotate the mouse ball cover counterclockwise
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.
