PDF schematic named z60 with a BV1 suffix, 1.50 MB in size. The name does not identify the brand or board number, and the BV1 token may denote a revision or version, but that cannot be confirmed. Its size matches the plain z60 schematic, so the two are likely closely related. Use it to trace power rails and signals and to identify parts around a fault. Verify the title block code against your PCB before relying on any values.
