Look at the seam between the two halves of the box, there are two "tabs" close together, twist with little force a flat object there and it will pop apart.
Just looked online and see that 'SDS' is just an abbreviation for Star Diagnostics System. Makes sense now!
I have ordered a Star C3 system (thanks to lots of help from David) but will need to wait for it to arrive.
