Answer
Hi, Mick.  Your radio should display a pattern in the display if you hold in the "4" button while turning the radio on.  If you can tell me the pattern, I should be able to give you the radio code.

If all the possible elements in the pattern are displayed, it'll look like this:

  _ _ _
| _ _ _
| _ _ _

I'll need you to tell me which ones are present.  You can refer to them as "the number 1," top row center, or middle row left, for example.
