3. Spray liquid cleaner (such as window cleaner spray or a product designed for
cleaning office computer equipment) onto a soft cloth to wipe the keys and keyboard
housing clean.
Warning: Do not spray liquid cleaners directly onto the keyboard. Avoid letting
any liquid seep below the key caps.

5. Use either a canned air type office supply cleaning equipment or a small vacuum to
remove dust or foreign objects between the keys.
6. Connect the keyboard cable. The keyboard is now ready for use.
