I am not quite sure which instructions you are looking for, but there are a whole load of manuals on this part of the Bachmann Site :- Bachmann DCC. You probably need the Sound Decoder Manual, if you are looking for details on how to modify the behaviour of the Sound Decoder.
The sound decoder manual is 52 pages, and there is no need for anyone on this forum to scan them, when they are readily available from the manufacturer. Of course, if you have any more speciifc questions, please don't be put of by all the information I have just thrown at you, ask away and I am sure someone will answer.
