The RRST01 is an infrared remote designed as a replacement for the Hitachi RC472, compatible with Roku streaming players and Roku TVs 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 buttons for easy operation. 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 remote, it requires direct line-of-sight and does not support RF functions such as voice control or private listening.
