The Emperor EMP300MCD21V Linear Multi-Code One Button Remote is a single-channel replacement transmitter designed for operators and receivers that use Linear’s Multi-Code fixed-code format at 300 MHz. Ideal for residential or commercial garage doors and gate openers, it provides dependable one-touch control and a straightforward upgrade or spare for Multi-Code systems. The transmitter uses the Multi-Code coding scheme and is engineered to work with compatible 300 MHz Multi-Code receivers and operators from Linear/Nortek and other systems that explicitly support the Multi-Code format.
Programming is simple: set the internal DIP switches to match the code pattern on your existing Multi-Code receiver or working remote, then press the button to operate the door or gate. Because this transmitter uses a fixed-code architecture, it is not compatible with rolling-code platforms (e.g., Security+ or Intellicode). For best results, ensure your opener or external receiver is labeled Multi-Code at 300 MHz before purchase. Typical applications include replacement or additional remotes for garages, community gates, warehouses, and light commercial access points. Follow local safety guidelines and keep remotes out of reach of children.
