Some versions of WebApp will include a firmware update for ZonePad. This update will automatically push to connected ZonePads after the Zone Controller has been re-booted.
The ZonePad update will be signified in multiple ways.
On ZonePad
Mic/Music button will pulse and the LED wheel will move clockwise to indicate the percentage of the update.
On Zone Front Panel
Power LED will flash orange (see also Zone Processor LED States). The Zone LED will also flash corresponding to the Controller Input port the ZonePad is connected to. If multiple ZonePads are being updated, multiple Zone LEDs will flash.
In WebApp (version 1.4.0 and above)
A banner will show at the bottom of the browser signifying that a ZonePad update is occurring along with a status bar of the update progress. This information can also be found in Settings > Devices > Wall Controllers. See WebApp - Wall Controllers and Paging Stations
