Desolder both battery wires and both button wires (red rectangles). Gently bend them away from the board, being careful not to pull on them.
Unscrew the 4 screws holding the main board down (blue circles). Slide the board to the right slightly, then lift it out. Place the screws in a pile designated "A". There are two different kinds of screws, as seen later.
