About wireless power saving
The Wireless Power Savings feature saves power by turning off power to the wireless radio inside the speaker when the device is connected to an Ethernet network. If you disconnect the Ethernet cable from the speaker, Wireless Power Saving will automatically turn off and the wireless radio will turn on so that the speaker can be discovered over your wireless network.
NOTE
If Wireless Power Savings is ON, Wi-Fi power will be temporarily turned on when accessing the “My Devices” - (“Device Name”) - “Network” screen in the HEOS app or whenever the CONNECT button on the device is pressed.
