The RRST01 is an infrared remote designed as a substitute for the Roku RC-C1R, compatible with Roku TVs and streaming players from TCL, Hisense, ONN, Sharp, Philips, RCA, Westinghouse, and similar brands. It provides Power, Volume, Mute, Sleep, and streaming shortcuts with large mechanical keys, front-facing volume controls, and a secure screw-in battery cover with tassel. The remote includes a learning function to program commands from an original TV or audio remote for extended control options. As an IR-only device, it requires direct line-of-sight and does not support RF functions such as voice control or private listening.
