    The manual you linked me to seems to be the correct one, but it does not show how to retrieve the pre-set songs on the keyboard.

    That is not the problem. I don't remember how to retrieve the pre-set songs in it. So, I guess I am just stuck and there is no resolution to the problem. Thank you anyway.

    Thank you very much, but I believe the matter is closed. I am 78 years old andcan't remember things any more. There were instructions to push certain numbers to retrieve specific pre-set songs. It may have been on another keyboard-- Yamaha instead of Casio. So don't try any more.

It was a bit difficult to find that manual for free but I got one link from where you can download it for free.
Here's the link
It's direct link to pdf file of your manual so it might take a bit of time to open up. Once it is fully opened i.e. all pages in your browser kindly click on file and save as and keep it with you.
In case you face any trouble kindly let me know.

    sorry for the delayed reply, Your keyboard has tones bank and in my view it seems that it has gone bad. As of now you require to change the tone bank itself. There is nothing such as retrieving it back as it is not compatible with any pc software. You need to purchase a new tone bank and install. Here is a link from where you can get one.

    Just give me anything you remember on retrieving tones back. I will dig out the remaining procedure.
