Compatible with Hörmann EcoStar 433.92 MHz rolling code remote controls. 2. Not compatible with the EcoStar BS series and the Liftronic II series. 3. High-quality replacement product, easy to program and use. Please open the receiver from the garage door before programming. STEPS: 1. Press the programming button. (On some receivers, the programming button must be held down.) 2. The LED on the receiver indicates that programming mode has started. 3. Press and hold any button on the new remote control for one second, then release it. 4. The LED on the receiver will light up or turn off to indicate successful programming. 5. Wait a few seconds to exit programming mode. Programming is complete. Why doesn't the LED light up, or only dimly, when you press the buttons on the illuminated remote control? This could be due to a dead or weak battery. If the indicator light still doesn't illuminate after replacing the battery, check if the button or the remote control is damaged. Attention!
