Another Radio Code Question

[crackerman]

Hi,

Had battery problems as well with our '94 855 turbo. I tried using the first radio card I found on glove box. That code did not work. Then found another set of cards. Tried that code once. Then the screen read off. The manual says I can wait 24 hours and then I get another 3 shots. So I am going to try again tonight. This radio is not listed in the owners manual (it was upgraded based on new set of cards in glove box) so I am not sure if I need to enter anything else after the code. So my question is do need to enter anything else after the numbers on this radio model shown below?

Thanks
