most you can't but I have book for scantronic 9452 and on the back if they still exist is Scantronic Ltd Perivale Industrial Park Greenford Middlesex UB6 7RJ. telephone 0208-991-1133. Fax: 0208 997-4448. the original area code was 081 which now doesn't exist. No guarantee they are still there.
The user book doesn't help but if you want the user book then using the answer page to your question put your email address in and I'll send it as attachment. Ensure in your email address you leave a space where the normal email address for AT goes or you can't post either questions or answers using that symbol the forum won't accept it.
