Simple question on key insertion...

[batracom]

Hi guys, I am abroad at the mo and watch sat tv with a mate whose reciever is patched to allow manual key insert. Just a question: I was looking at the key section (Slovenia TV to name an example) and there is a whole set of keys, from index 09 to index 0D or 0E. Should we enter all of them or do we just need to enter the current one on Slovenia's ident?
Thanks

You always need only that key which is in use
