A. The Rayzar z1 works with any TV or device that has an ATSC tuner. Devices that may have built-in ATSC tuners include TVs, laptops, PCs, some satellite receivers, and digital recording devices (DVRs). Tip: Any television manufactured after March 1, 2007 is required by U.S. government to have an ATSC tuner. If your TV menu has an option for scanning for digital channels, then your television has an ATSC tuner.
