18.1 Cleaning the Keyboard
The keyboard may be cleaned whenever deemed necessary simply by temporarily
removing it from the system and wiping it with a damp cloth. If a conventional
spray type cleaner is required, spray the cloth first, then wipe off the surfaces. Do
not use petroleum based cleaners or cleaners containing benzene, triclorethylene,
ammonia or acetone, as these cleaners could damage the plastic surfaces.
