Backup archive whose name holds only a timestamp, 10 October 2016 at 16:22, with no device model, so its origin is unclear. The RAR is about 4.98 MB and probably contains a flash readout taken from a receiver or similar device. Treat it as an unidentified dump: inspect the contents, look for model strings inside the image with a hex editor, and compare its size with the target flash chip. Only write it to hardware you can positively match, and keep a backup of the original chip first.
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.
