The RRST01 is an infrared remote designed as a direct substitute for the Roku RC108, compatible with Roku streaming players and televisions from TCL, Hisense, ONN, Sharp, Philips, RCA, and Westinghouse. It provides Power, Volume, Mute, Sleep, and streaming shortcut buttons 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 operation and does not support RF functions such as voice control or private listening.
