When removing the parts from the calculator be careful not to break any wires or ribbons. The solar panel, screen, and lower circuit board should remain connected throughout this guide.

Lift the top edge of the solar panel with a finger and slide it away from the circuit board to disconnect it from the calculator.

Carefully pry the screen out of the calculator with a prying tool or spudger.

Pry the lower circuit board from the calculator by inserting a prying tool between the base of the calculator and the circuit board.
