Small 81.5 KB RAR archive named R9600L, without a brand, revision or board number in its name. Its contents cannot be identified from the name alone, so unpack it to see whether it holds a schematic, a boardview or firmware. A related R9600L V10 archive is larger, so this may be a different or partial package, but compare the two to be sure. Make sure the model and PCB revision match your unit before relying on it. Back up any original firmware before reflashing.
