Step one:

Follow the RGR910 user manual below to pair RGR910 and your existing opener. It requires to activate the learn button, please use the button I (one) to pair.    

Step two:  

If RGR910 is working with your opener， connect it with your Smart garage opener ‘Signal Control Cable’. The wiring clip supplies an easy connection. Then your smart garage door opener can control the RGR910 button one. That means your opener is compatible!  

* Note: The wires connect to button one, so only button one is working.
