Cleaning the Keyboard/Mouse
Make sure that the workstation 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.
Make sure that the workstation is off-powered (the POWER/SLEEP lamp goes off).
2.
Turn the mouse upside down, and rotate the mouse ball cover counterclockwise to remove
it. Take out the ball from the mouse.
