There should be a display on the bottom of the system if it's a EZ36 system if not then it's a EZ18 system and you just have to program in the dark so to speak. Have those overlays as well.
If you want a quote on replacement can get you that as well.

Yes here is a digital display at the bottom. Going to PM's now. For some reason I am not getting email notifications when posts are made to this thread. Thanks
