You can control your speaker with the included remote control or with a different remote.
If your TV supports HDMI-CEC, connect it to your Bose speaker using an HDMI cable. HDMI-CEC allows your speaker to receive volume commands and automatically turn on or off with your TV. This way, you can continue to use your current remote control that you are familiar with to control your Bose speaker
Tip: If you're unable to control your speaker, check that CEC and ARC are enabled in the TV menu. TVs may refer to CEC by different names.
If your TV does not have HDMI or does not support HDMI-CEC, you can use a third-party programmable IR remote
