CAUTION: A video source (such as a video game, compact disc interactive [CDI], or TV information channel) that shows a

source, the pattern of the nonmoving portion of the game (or other source) can leave a permanent image on the picture tube.
When you're not using the video source, turn it OFF. Also, regularly alternate the use of such video sources with normal TV
viewing.
