Hi guys! I need a little help here. I'm installing a motorized FTA dish in my back yard but I don't have the manuals for the dish or the motor. I bought this system with motor years ago from Sadoun (Digipower SG2100). Looking at the image with the motor, to set up my latitude which is the marker that I use to set the latitude? I've circled the two possibilities in blue. Same thing for the dish elevation, I believe for the dish it's the edge that I've circled in red.
