1.8.1.5 Cleaning of keyboard/mouse
To clean the keyboard, please firstly confirm the entire system including the Express server
and the peripheral devices are turned off, and then wipe the surface of the keyboard with a
dry cloth. For normal use of the mouse, the internal mouse ball needs to be able to rotate
smoothly. To prevent the mouse ball from getting dirt, please use the mouse on a clean place
with less dust and clean it on a regular basis according to the following steps.
(1) Confirm the AC power breaker of the Express server is turned off.
(2) Turn over the mouse, turn around the mouse ball cover counter-clockwise, and take out
the mouse ball.
(3) Wipe off dust on the mouse ball with a soft dry cloth.
If you cannot wipe off dust, please soak the cloth slightly in cold or lukewarm water
diluted with mild detergent.
(4) Wipe the three small rollers inside the mouse with a cotton swab or an equivalent.
If you cannot wipe off dust, please soak the swab slightly in alcohol.
(5) Replace the mouse ball into the mouse.
If you moistened the mouse ball or the roller in Step 3 or 4, please dry up them before
replacing them into the mouse.
(6) Replace the mouse ball cover into the back of the mouse, and turn it around clockwise
to lock it.
1.8.2 Replacement and Storage
The Express server must be replaced or stored only by the maintenance engineer.
