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 64) 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 64) 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.
