You can enable standby (low power) mode by deactivating Wi-Fi, clearing the Bluetooth® pairing list and disconnecting the Ethernet cable. Deactivating Wi-Fi and removing the Ethernet cable will prevent the soundbar from connecting to your network, as well as preventing the system from being controlled by the Bose Music app until Wi-Fi is re-enabled or the Ethernet cable is reconnected.
Note: Prior to deactivating networks or entering standby mode, use the microphone on/off button to ensure the microphone is turned on (the red indicator light will be off).
