Using a Remote Control with your Soundbar | Bose Lifestyle Ultra Soundbar
Enable the HDMI-CEC function of your TV to control the soundbar with its remote.
The Lifestyle Ultra Soundbar connects to your TV via an HDMI cable and uses HDMI-CEC (Consumer Electronics Control) to sync power and volume control. This allows you to operate the soundbar using your TV remote control, or one from another device connected to the TV; such as a cable or satellite box. HDMI-CEC is often enabled by default.
If the remote control of your TV does not control the volume level of the soundbar, check the settings menu of the TV to ensure the CEC function is turned on. If you are using the remote control of a device connected to the TV, verify that CEC is enabled on both the TV and that device. The CEC function may be labeled differently in the settings menu depending on the manufacturer. To view a list of trademark names for this function, see Consumer Electronics Control.
