Cleaning the keyboard

CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from under the keys.

●If the keyboard has an on/off switch, turn it off.

●Follow the safety precautions in the Maintenance and Service Guide for your workstation before cleaning the computer.

●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.

●Clean under a key with a swab moistened with isopropyl alcohol and squeezed out. Be careful not to wipe away lubricants necessary for proper key functions. Allow the parts to air dry before reassembly.

●Use tweezers to remove any fibers or dirt in confined areas.

Cleaning the monitor

●Follow the safety precautions in the Maintenance and Service Guide for your workstation before cleaning the computer.

●To clean the monitor, wipe the monitor screen with a towelette designed for cleaning monitors or a clean cloth moistened with water.

CAUTION: Do not use sprays or aerosols directly on the screen—the liquid might seep into the housing and damage a component.

Never use solvents or flammable liquids on the monitor because display or housing damage may result.
