Combine 4 remotes into just 1 Reduce the clutter on your coffee table & consolidate the remotes of the following 4 device types into 1 remote control: TV, Cable / Satellite / DVB-T / Freeview, DVD / Blu-ray & audio / amplifier/ home cinema. URC 1240 makes it easy & affordable to clean up the pile of remotes in your living room. What exactly is a universal remote? A universal remote is a remote control that operates TVs and/or audio & video devices of any br&. One For All invented the universal remote control decades ago for two purposes: replacing broken or lost remotes & to combine all remotes of a household into just one. The URC 1240 does both. If you want to control more than 4 devices, we advise a URC 1280 or our Smart Control (URC 7980). How does it work? The One For All Contour 4 contains codes for controlling over 1500 brands of Audio/ Video devices. 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. & from then on, your universal remote will function just like your originals, with the benefit of using just 1 remote!
