Cleaning The Keyboard/Mouse - NEC Express5800/A1080a User Manual

Cleaning the Keyboard/Mouse

Make sure that the server and peripheral devices are powered off (the POWER/SLEEP LED is
unlit), and then wipe the keyboard surface with a dry cloth.
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. Follow the steps below regularly to
clean the mouse:
1. Make sure that the server is powered off (the POWER LED is unlit).
2. Turn the mouse upside down, and rotate the mouse ball cover counterclockwise to remove
it. Take out the ball from the mouse.
3. Wipe the mouse ball with a dry soft cloth.
Or, soak a soft cloth in neutral detergent that is diluted with cold or lukewarm water, and
squeeze it firmly. Rub off stains on the mouse ball.
4. Wipe three small rollers inside the mouse with a cotton swab soaked with alcohol.
5. Put the mouse ball back into the mouse.
If the mouse ball or roller is wet in Step 3 or 4, be sure to fully dry it before putting the mouse
ball in the mouse.
6. Place the mouse ball cover, and rotate it clockwise until it is locked.
