Casio JF-100TE Battery Replacement
Taking the back off The Casio JF-100 calculator is similar to the ...TE. Remove the two screws at the top back. Place a small screwdriver blade along the seam where the back plate fits into the front plate. There are 3 fasteners on each long side and 1 fastener on each of the front and back sides. Find the spot where it's the easiest to separate the back plate from the top plate (there are only two). Carefully twist the blade to cause an opening. Then proceed sequentially around the perimeter releasing each fastener. The front plate will easily separate from the back plate at this time. There are no parts that will fall-out--don't worry. Replace the battery. Press the front and back plates together to snap the fasteners.
