This replacement remote control is pre-programmed for the Hisense 75U800GR Roku TV and requires no additional setup or programming. It provides RF-based voice control, private listening through the built-in headphone jack, and direct access to popular streaming apps, making it ideal for original Roku TV operation. Designed for Roku TVs only, it will not work with Roku streaming players, Roku sticks, or non-Roku Hisense TVs.

Warning: Check the substitute to ensure it has all the necessary functions.
