Schedule screen changes
You can schedule assignments of content to screens so that they happen automatically on particular days or at certain times of day. Once you've created a schedule, you can assign it to a screen in just the same way as a playlist.
To do this, you select the Scheduling pane.

Click the ADD button in the bottom right to create a schedule, and follow the links to give your schedule a name.
Then you'll see a calendar style view of the week.

You can use the 'ADD' button, or click and drag out a time during a day, and a window will appear which allows you to specify the start and end times, the source to be displayed during that period, and whether you want the assignment to happen just on that one day, or whether it should repeat periodically, for example, every day, or once a week.

When you've finished creating your schedule, you can click one of the top-level section tabs to return to the main control panes. The schedule will appear on your Assignment screen and you can drag and drop it onto the screens where it's needed, just like any conventional source or playlist.
During periods when nothing is specified in the schedule, the screen will blank, and, if your display allows it, go into standby mode. This is very useful for saving power overnight or when a building is unoccupied. But it can be disconcerting if your screen goes blank when you do the assignment and you don't know why. You know now!
