English 6. Cleaning - Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for cleaning. Periodically clean the liquid crystal panel of the display to ensure a clear screen and prolong the service life of the panel. Use a clean, soft and cotton-free dry cloth to dip into the specific cleaner for the liquid crystal panel. Quickly wipe over the whole panel and use another cloth to clean the panel. 7. Ventilation - The vents and other openings in the cabinet are designed to let hot air escape from the display. Do not cover or block these vents and openings since insufficient ventilation can cause overheating and/or shorten the life of the product. Do not place the display on a bed, sofa, rug or other similar surface, since they can block ventilation openings. This display is not designed for built-in installation; do not place the product in an enclosed place such as a bookcase or rack, unless proper ventilation is provided or the manufacturer's instructions are followed. 8.
