The RRU401 is the compatible replacement for the Mitsubishi 290P123A10 remote control. This universal remote consolidates control of up to four devices—TV, Blu-ray player, streaming device, soundbar, or AV receiver—into a single unit with broad compatibility across major brands. The full backlit keypad provides visibility in low light, while dedicated smart buttons for HOME, NETFLIX, and APPS deliver quick access to streaming content. Advanced learning and macro capabilities let you program custom functions and multi-device commands, with setup simplified by an extensive built-in code library; use code 2657 when programming for Mitsubishi TVs.
