Cleaning the Keyboard/Mouse
Make sure that the server and peripheral devices are all off-powered (the POWER/SLEEP lamp
goes off), 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 to clean the
mouse regularly:
1.
Prepare cold or lukewarm water, neutral detergent, alcohol, two dry soft clothes, and cotton
swabs.

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.
