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 microfiber 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.
