Inserting security code ?

I have had to change the battery on my Ka and now the radio does not work.
I have the code for it, but, because I live in Portugal the instructions are in Portugese. A further complication seems to be the fact that there are two 8's in the code.
Can someone tell me in simple terms how to input the code.
There is another problem.........The LCD readout is not clear. The readout is incomplete.
