The RMC12249 is a ready-to-use replacement remote for Sony DVD players and DVD/VCR combo units, modeled after the Sony RMT-D240A. No programming is required—it works straight out of the package with compatible devices. This remote features essential controls including MENU, SLEEP, DISC MENU, and full playback functions. It is designed exclusively for Sony DVD and DVD/VCR combo players and cannot be programmed for other devices such as TVs or cable boxes. The RMC12249 operates on a fixed DVD3 code set; if your unit displays "DVD1" or "DVD2," use your original Sony remote to reset it to DVD3. This model serves as a compatible substitute for numerous Sony remote controls and is ideal for restoring full functionality to your Sony DVD playback equipment.
