Caution Precautions for touch-screen operations Do not use sharp objects such as fingernails or ballpoint pens for touch operations. Do not use wet fingers for touch operations. If the screen has any moisture or if your fingers are wet, the touch-screen panel may not respond or malfunction may occur. In this case, turn off the power and wipe off the moisture with a cloth. Attaching any commercially available protective sheet or sticker on the screen may impair responsiveness to touch operations.
