Configuring automatic RF sync

The automatic RF sync is recommended for single-room installations.

If you have a multiroom installation, receivers from different locations may synchronize across locations if the RF power is set too high.

In order to configure an automatic RF snyc:

Navigate to the Locations view.
Click on the name of the location to select all devices of the location.

If there are multiple locations in the Locations view, we recommend the manual RF sync mode.
Open Properties > RF Settings on the selected device(s).
Click Edit to configure the settings.
In the pop-up menu, select automatic mode and click OK.
Restart all receivers one after another.

The first restarted receiver will automatically become the master receiver. The other receivers will be the followers.

The automatic RF Sync has been configurated successfully.
