1. Settings- You will need your Apple TV remote until the process is complete. With your Apple TV on, use your Apple TV remote to go to Settings, then General, then Remotes, and finally Learn Remote. After that, click Start.
2. Universal remote- Using your universal remote, select a function that has not been used yet (TV, DVD, etc.). Now, follow the on-screen instructions. You will press and hold the up, down, left, and right arrows, watching the progress bar as the Apple TV learns each button. After this is done, press and hold Select and Menu.
3. Renaming- You can rename the remote if you choose or skip.
4. Playback buttons- You can have Apple TV learn your playback buttons (pause, rewind, fast forward, stop, skip forward, skip back, play, etc.). Once you complete this, the process is complete and your universal remote will now have the ability to control your Apple TV.
