      • Put the tweezers (in their closed state) into the indentations on the side of the calculator.

      • Slowly open the tweezers, to split the calculator into two halves.

      • On certain build batches of this calculator, glue was used to better hold the halves together. You might have to use a card to split the two pieces.
