This graphic shows the postal code set up screen.If any of these boxes could be faulted it is the postal code settings choice. The less dexterous will have problems.
The argument is there for those unable to use the postal code set up an engineer will set it for them but we feel although this menu is needed to check TV licence holders it is a worthless exercise as anybody wanting a Freesat box will give out false information anyway and simply pay cash in exactly the same way as they do at present for any item that requires personal information.
