Ä
CAUTION: Do not use liquids of any kind on the keyboard, because
they may permanently damage your keyboard. Do not use a regular
vacuum cleaner to clean the keyboard, because you may deposit
normal household debris on the surfaces, rather than remove it.
Clean the keyboard regularly to prevent keys from sticking and to
remove dust, lint, and particles that can become trapped beneath
the keys. Ideally, use a can of compressed air with a straw
extension to blow air in and around the keys.
