CLEANING THE KEYBOARD
177
Appendix G
Cleaning the Keyboard
Follow all safety precautions stated earlier before cleaning the keyboard.
When cleaning debris from under the keys, review all rules in the previous section, then:
CAUTION Use safety glasses equipped with side shields before attempting to clean debris from under
the keys.
„
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. Caution should be used as
too much air pressure can dislodge lubricants applied under the wide keys.
„
If you remove a key, use a specially designed key puller to prevent damage to the keys. This tool is
available through many electronic supply outlets.
CAUTION Never remove a wide-leveled key (like the space bar) from the keyboard. If these keys are
improperly removed or installed, the keyboard might not function properly.
„
Cleaning under a key can be done with a swab moistened with isopropyl alcohol and squeezed out.
Be careful not to wipe away lubricants necessary for proper key functions. Use tweezers to remove
any fibers or dirt in confined areas. Allow the parts to air dry before reassembly.
Cleaning the Monitor
Follow all safety precautions stated earlier before cleaning the monitor.
To clean the monitor, wipe the monitor screen with a clean cloth moistened with water or with a towelette
designed for cleaning monitors. 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.
Cleaning the Mouse
Follow all safety precautions stated earlier before cleaning the mouse.
To clean the mouse:
„
Clean the mouse ball by first removing the retaining plate and the ball from the housing.
„
Pull out any debris from the ball socket and wipe the ball with a clean, dry cloth before reassembly.
