Nokia 3390 schematic file, 911 KB, saved as PDF with an uppercase extension. Only the model appears in the name, with no board revision or version. Technicians use these diagrams to trace power from the battery contacts through the regulators, follow keypad, display, buzzer and audio lines, and isolate a component shorting a rail. Any PDF viewer opens it regardless of the extension case. Check that the drawing corresponds to the board inside the phone before trusting component positions.
