A:Answer Hi Tony! Thank you for reaching out to us. If the pre-programmed codes don’t cover all functions, the Insignia remote has a learnability feature: hold down the device button (e.g., TV) and the MUTE button simultaneously. The remote will enter learning mode, allowing you to press the corresponding button on your original TV remote (e.g., the mute button). The Insignia remote will learn that function and store it for future use.
