I'm going to get a Matrix Orbital. One without the keypads on the faceplate. I'm guessing that I can still program the Orbital without the keypads. But, what are the differences in the 4 series and the 5 series?
Hello, the MX4 series is LCD (Liquid Crystal) technology. The MX5 series units are VFD (Vaccum Florecent) technology, making them slightly more expensive due to clarity, viewing angles, filter options etc.
