content: All you have to do is say something along the lines of "I want to cooperate fully and I'm willing to answer any questions you have, honestly and to the best of my ability, but you understand that if I'm being questioned in connection with [whatever crime], I will have to do so with an attorney present. As soon as I have an attorney present I'll be happy to answer any questions you'd like to ask."      Simple, respectful, reasonable, and the sort of thing a prudent person, even an innocent one, might say.     You want to sound like a prudent and diligent adult making an informed legal decision, not a criminal or a cop hater who 'knows his rights'.
