CRoutine Care
General cleaning safety precautions
●
Never use solvents or flammable solutions to clean the workstation.
●
Never immerse any component in water or cleaning solutions; apply any liquids to a clean cloth
and then use the cloth on the component.
●
Always unplug the workstation before cleaning the keyboard, mouse, or air vents.
●
Always disconnect the keyboard before cleaning it.
●
Wear safety glasses equipped with side shields when cleaning the keyboard.
Cleaning the workstation case
●
Follow the safety precautions presented (
Service considerations on page 66) before cleaning the
workstation.
●
To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab.
●
For stronger stains, use a mild dish washing liquid diluted with water. Rinse well by wiping it with
a cloth or swab dampened with clear water.
●
For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is required because the alcohol
evaporates quickly and does not leave a residue.
●
After cleaning, always wipe the workstation with a clean, lint-free cloth.
●
Occasionally, clean the air vents on the workstation. Lint and other foreign matter can block the
vents and limit the airflow.
Cleaning the keyboard
CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from
under the keys.
●
Follow the safety precautions presented (
Service considerations on page 66) before cleaning the
workstation.
●
Visible debris underneath or between the keys can be removed by vacuuming or shaking.
●
Canned, pressurized air can be used to clean debris from under the keys. Use caution because
too much air pressure can dislodge lubricants applied under the wide keys.
●
If you remove a key, use a specially designed key remover to prevent damage to the keys. This
tool is available from many electronic supply outlets.
CAUTION: Never remove a wide key (like the space bar key) from the keyboard. If these keys
are improperly removed or installed, the keyboard might not function properly.
