  If your Casio Musical Instrument sounds strange, and restarting doesn't help (for example, note intensity doesn't change with key pressure), the “Back up” feature might be on. Turn off “Back up”, then turn the power off and on again.

Why does my Casio Celviano AP-250 Musical Instrument take so long to turn on?

  If it takes a long time to be able to use your Casio Digital Piano after turning it on, it could be due to corrupted memory data from a data transfer that was in progress when you last turned it off. The piano will perform a memory format operation, which takes about 20 seconds. Wait for this to complete. Avoid turning off the Digital Piano during data transfers with a computer.

  To transfer data after connecting your Casio digital piano to a computer: 1. Verify that the USB cable is properly connected to both the digital piano and the computer, and that your computer’s music software has the correct device selected. 2. Turn off the digital piano, then exit the music software on your computer. Turn the digital piano back on, and then restart the music software.
