Glyn,

Denon offers complete code sets on paper, for most of their products. In the Pronto forum, you can find a utility which was contributed by Paul Friedlander. (I think this is his name).

You run this utility and punch in a few of the code sniplets from the Denon doc and it puts out a completed code string for a Pronto. In most cases, you should be able to copy and paste these hex strings into your Nevo SL configuration.
