Yaesu: Yaesu FT-250R disassembly

Does anyone know how to disassemble a FT 250R? I need to remove the rea case so I can fix the battery contacts that we accidently moved while trying to open it up but couldn't fully open. I searched for a pdf or some instructions with-out luck. The manual shows the exploded view but doesn't say how to open it. Thanks

should be like most handhelds remove spanner nut from around antenna connector and switches on top of unit open speaker mic charging cover and then should come out fairly easily.

Ok I'll check that thanks. It looks like it would separate around those knobs but I'll check again. Have to see if I have a socket to do that.
