The RC-GZ1 is a universal remote control engineered for compatibility with nearly all Roku devices and Roku TVs, including Streaming Stick+, Roku Ultra, Premiere, Streambar, and televisions from TCL, ONN, Hisense, and Sharp. Voice control functionality enables hands-free content search, channel launching, and menu navigation, while standard controls manage volume, input switching, and app access. Setup requires battery installation followed by pressing the pairing button while powering your Roku device for automatic recognition. The RC-GZ1 replaces legacy models RC-FA5, RC-AL5, RC-AL2, RC-FA1, and RC-81, though app shortcut button configurations may vary by unit.
