Im installing a motorized FTA dish/motor and I am a bit puzzled over something. While following the instructions on setting up the SG2100 for correct elevation/latitude for my area I noticed on one side of motor base I have elevations listed and on the other side I have latitudes listed. Neither of those numbers match up however when Im trying to adjust the motor. For example If I set the elevation side to 40 degrees the latitude mark on the other side is something like 46 degrees. What side of the base should I be using for setting up the correct elevation/latitude for my area? Should I use the elevation side or the latitude side?
