Emergency playlist & failover
An emergency playlist is a fallback that a screen switches to when its normal content can't be loaded — so a screen never sits blank if something goes wrong.
What it does
If the current playlist's download/update fails, the device can switch to a designated emergency playlist instead of showing nothing.
The emergency playlist has its own identifier and its own volume level (used by the Control App), so an alert can be louder or quieter than normal content.
When it triggers
A playlist update can't be downloaded (e.g. network/time-sync failure).
As a safety net for unattended screens at remote sites.
Setting it up
Configure the emergency playlist identifier and volume in the device settings (see All settings reference → Playlist). Pick content that's always valid as a fallback (a logo loop, a generic brand message, or safety information).
