The product settings of individual devices can be controlled from the Bang & Olufsen app. Important controls include setting products up on your home Wi-Fi network, renaming the device, updating product software, enabling Chrome Cast, checking battery life and other settings.
This can be accessed from the Settings page in the Bang & Olufsen app, which is the top corner in the Home tab. Here, click on My Products. This will show a list of available products. Clicking on each product will let you reach its device settings and configurations.
More information about what settings and configurations are available for your product will be available in the product's own user guide.
