Diane - Learn TV Remote is a feature designed to help users become familiar with the layout and function of each button on the Samsung remote. When enabled, pressing any button (except the Power button, which will still turn off the TV) will prompt the TV to announce the button’s name and its purpose – without affecting TV operation.
This teaching mode is especially useful for users who are visually impaired or new to Samsung remotes. To enable this feature, go to: Settings > All Settings > General & Privacy > Accessibility > Learn TV Remote. To exit, simply press the Return key twice.
