Dump archive, version 3.6, whose name lists the satellite positions 4W, 5E, 13E and 75E, which suggests preset channel and satellite data for those orbital positions. It is 3.53 MB as a RAR file, and the (1) suffix marks a duplicate copy. The target receiver model is not stated, so inspect the contents and confirm that the device matches before writing it. A full dump is normally loaded with a programmer or a service tool, so back up the existing flash first and check that the image size fits the chip.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @tvsoftwareworld. Enginerys does not host this file.
