Casio Support

I have a 1988 casio cdp 3000 that has built-in play of classical piano pieces. It came with the a book containing the piano notes for each piece. I can\'t find it. Can you PLEASE let me know if there is a pdf of it that I can download? I am sure you have a database. I really need this. Would very much appreciate your help.

Where is the memory battery located in the keyboard? Are there certain keys to depress when doing a hard start?

when the camera is switched on, always back lamp is lit on

I just turned it on, and the blue light is on but nothing will work...can\'t set the piano, no sound, NOTHING....HELP!! I was just playing it last night and it was fine.
