      If the message “Sampled!” appears on the display when you release the SAMPLING button on your Casio Electronic Keyboard, even without input from the built-in microphone, perform the sampling operation in a quiet environment. Also, release the SAMPLING button carefully to avoid making noise. Alternatively, turn off SampAuto and try manual sampling.
