Turning HDMI-CEC on or off

CEC (Consumer Electronics Controls) is a way for communications and operations to occur between devices connected with HDMI cables. This feature allows for one device to control basic functions of another device, such as turning a device off or change the selected input of a TV.

To turn HDMI-CEC on or off:

  1. In the SoundTouch app, select Menu > Settings > Speaker Settings, then select your system
  2. Select Advanced Setup > HDMI-CEC
  3. Tap the circle next to the desired option to select it:
    1. Default On Enables CEC
    2. Alternate On: Try this setting if you cannot control or experience unexpected control with certain devices
    3. Off: Disables CEC
  4. Tap the X toward the top of the app to exit the menu
