The Transmitter Solutions EMP310LID21V Emperor Linear Delta 3 One Button Remote is a single-channel garage door and gate opener transmitter designed for systems that use the Linear Delta-3 fixed-code protocol at 310 MHz. Ideal as a replacement remote or spare, it operates doors, gates, and access receivers in residential and light commercial applications that are specifically set up for Delta-3 technology. Its one-button layout keeps everyday operation simple while providing dependable performance with compatible Linear Delta-3 receivers and operators.
This Emperor-series remote uses an 8-position DIP switch for programming; to set it up, match the switch pattern to your existing Delta-3 remote or the DIP switches inside the receiver. It transmits at 310 MHz and is powered by a 9V battery, with an indicator LED to confirm button presses. A visor clip is typically included for convenient in-vehicle mounting. Compatibility is limited to Linear Delta-3 fixed-code systems and most comparable 310 MHz, 8-DIP switch-programmed transmitters (such as Linear Delta-3 DT/DNT00002A). It is not compatible with Linear MegaCode 318 MHz, LiftMaster/Chamberlain Security+, Genie Intellicode, or other rolling code systems. For best results, verify your opener or receiver specifies 310 MHz Delta-3 with DIP switch coding before purchase and programming.
