Cleaning the Keyboard

Follow all safety precautions in Section 3.1.1 before cleaning the keyboard.
To clean the tops of the keys or the keyboard body, follow the procedures described in
Section 3.1.2.
When cleaning debris from under the keys, review all rules in Section 3.1.1 before
following these procedures:
CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from
under the keys.
!
Visible debris underneath or between the keys may be removed by vacuuming or
shaking.
!
Canned, pressurized air may 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 may not function properly.
!
Cleaning under a key may be done with a swab dampened with isopropyl alcohol.
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.
