The Common Look and Feel Guidance prescribes that, on television, the text of alerts be displayed on either a crawler, or as a full screen notice that covers programming, in white text on a red background in both cases. Crawlers inserted by television channels are positioned at the centre of the screen out of respect for those inserted by broadcast distribution undertakings at the bottom of the screen. The guidelines note that "automated broadcast interruption need not be used if a person can present the text of an audience alert message verbally and visually mindful of the other guidance found in [the guidelines]."
