Cleaning an optional keyboard
WARNING! To reduce the risk of electric shock or damage to internal components, do not use a vacuum
cleaner attachment to clean the keyboard. A vacuum cleaner can deposit household debris on the keyboard
surface.
CAUTION: To prevent damage to internal components, do not allow liquids to drip between the keys.
To clean the keyboard, use a soft microber cloth or a chamois moistened with one of the cleaning
solutions listed previously or use an acceptable disposable wipe.
To prevent keys from sticking and to remove dust, lint, and particles from the keyboard, use a can of
compressed air with a straw extension.
