Keyboard
You need to clean the keyboard only if the key caps become noticeably grimy or if loose debris
has collected in the key wells.
To clean the key caps, use a soft, lint-free cloth. Spay a small amount of general purpose wall
cleaner (products such as 409
® or Fantastik ® ) on the cloth. Never spray anything directly on
the keyboard. Turn the keyswitch to OFF and remove the key. Wipe the key caps with a
circular motion until clean. Replace the key and you are ready to resume normal operation.
To clean debris from the key wells, use a vacuum cleaner with a drapery attachment. Use a
plastic attachment only, not a metal one, to avoid scratching the case. First make sure all clear
key covers are firmly seated by pressing down on each key. Then pass the vacuum attachment
over the keys without actually touching them. Any loose matter that has fallen into the
keyboard will be removed.
