Schematic for the Nokia 1616 phone, model code RH-125, in a 1.05 MB PDF. The RH code is Nokia's internal type designation, and it is the best way to confirm you have the right handset. Mobile repair technicians use these diagrams to follow battery and charging lines, check the power management IC, trace the keypad, display and audio circuits, and find the components behind a short. Open it in any PDF reader and compare part positions with the actual board.
