Just unscrew the back with a suitable tiny Phillips screw driver. Then remove the battery. Two more screws (silvery, flat) hold the PCB against the keyboard frame. Unscrew these, too.

Before you put the new PCB in, make sure that the adhesive foam doesn't get into your way. Cut it away where it interferes with the case (or shorten the small pins in the keyboard frame that press against the foam through the holes in the PCB).

Fasten the two flat screws and put back the battery. Reassemble the case.

If you have a program or data you want to keep you need to write it down before you disassemble the calculator.
