What exactly is a universal remote?A universal remote is a remote control that operates TVs and/or audio and video devices of any brand. One For All invented the universal remote control decades ago for two purposes: replacing broken or lost remotes and to combine all remotes of a household into just one. The purpose of the Contour TV remote is replacing your TV remote as it does not control multiple devices. For combining multiple remotes into one we advise a Contour 4 or Contour 8.How does it work?The One For All Contour TV contains codes for controlling over 700 brands of TV. You can try these using a simple 3 step process that takes only a few seconds. You will usually find the right code in the first couple of tries. And from then on, your universal remote will function just like your original!
