old dewalt?

Don't know what your on about,click your question and a picture of a battery drill comes up,my drill wont play tunes either.If it was a radio I would look for a little hole around the back or side or somewhere that you could stick a pen tip into it may have a sticker on it saying "reset" and stick a pen tip in it,but I would be quite happy just to drill holes with it,.
