The RR478M remote control replaces much of the original equipment Onkyo AV receiver remotes. The RR478M will work right out of the package for compatible Onkyo AV receiver models listed (but not limited to) without any programming. The RR478M is pre-programmed to work with Onkyo receivers. The remote includes popular features like the selection of the inputs, full menu controls, and, of course, all other buttons for normal operations. Please refer to your unit’s operating manual for instructions on using this remote.
