The easiest way to use RF (radio frequency) to control your TiVo DVR! Unlike IR (infrared), RF does not require line of sight between your remote and your TiVo DVR, and works up to 100 feet away. Convert your TiVo IR remote to an RF remote by
simply replacing one of the batteries in your TiVo remote with the supplied RF transmitter. Product includes RF receiver, IR emitter, and RF transmitter.
