Hi,
I just purchased a Casio CTK 4000 and am really enjoying it. However, when I set up a registration it worked fine until I shut the keyboard down and detached the adapter. Everything was lost. Is this a problem with an internal battery? I have a wk 3200 at home and there is no problem with it.
Thanks for your response.
