Alerts
Alert conditions are defined for each statistic in the Single Statistic settings. See section Single Stat for more information.
When an alert condition is triggered, the Single Statistic changes its background, font, and border colors, and it plays the alert sound (if defined) and periodically (if specified). See section Customizing Wallboard Styles for more information.
