Event Handler State

...

In some scenarios, you might want your presentation to sit at a blank screen. The Event Handler fills the role of an empty placeholder in your presentation. Here are a few cases where an Event Handler would be useful:

...

Although Event Handlers contain no content, you can add commands and interactive events into and out of them. For example, if you set an Event Handler state as the Home Screen and define a  BP900  event linked from the Event Handler state to the first presentation item, the display will sit at a blank screen until a user presses the BP900 button, and then the first item will begin playing. Alternatively, if you set an Event Handler as the Home Screen and add a  Synchronize  command to it, you can synchronize your presentations and/or displays before the first files begin playing.

The User Variable state allows to display text from User Variables in a Ticker zone. Select a User Variable to display from the User Variables dropdown list.
