Small RAR archive, about 115 KB, labelled H0222-SC, belonging to the same H0222 group as several related files. The name states no manufacturer or model, and the SC suffix is not defined, so the contents can only be identified after extraction. In similar collections SC sometimes marks a schematic, but that is not certain here. Open it with 7-Zip or WinRAR, review what is inside, and verify that any board code or revision matches the PCB in front of you before using it for diagnosis or repair.
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 @schematicslaptop. Enginerys does not host this file.
