The RRST01 is an infrared remote designed as a direct substitute for the Roku RC31, compatible with Roku streaming players and televisions from TCL, Hisense, ONN, Sharp, Philips, RCA, Westinghouse, and similar brands. It provides essential controls including Power, Volume, Mute, Sleep, and streaming shortcuts with large mechanical keys and front-facing volume access. The remote features a learning function that lets you program commands from an original TV or audio remote to expand control options. As an IR-only device, it requires direct line-of-sight operation and does not support RF functions such as voice control or private listening, and is not compatible with Roku Streaming Sticks.
