Your in the wrong section.

Google is your friend... Here is what google found:

http://www2.panasonic.com/consumer-electronics/support/Musical-Instruments/Technics-Musical-Instruments/Portable-Keyboards/model.SX-KN501

Download the manual there.

Do you mean SX KN501 or 5000? They don't list a KN500.
