The RC-GZ1 is a universal remote control engineered as a direct substitute for Roku RC-506 models, offering seamless compatibility with Roku Streaming Stick+, Roku Ultra, Premiere, Streambar, and Roku TVs from TCL, ONN, Hisense, Sharp, and comparable brands. 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 with your Roku device powered on 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.
