      If you cannot change the TRANSPOSE/TUNE settings on your Casio Musical Instrument, it might be because the keyboard is in SONG BANK mode. Press the SONG BANK button to return to the normal mode. It could also be that a demo tune is currently playing; stop the demo tune play to adjust the settings.

      If your Casio Musical Instrument isn't producing any sound when you press the keys, here's what you can check: * First, ensure the AC adapter is correctly attached and that the batteries are properly installed (+/–) and not dead. * Next, verify that the volume isn't set too low by using the VOLUME slider. * Also, make sure headphones aren't plugged into the PHONES/OUTPUT jack. * Check that the POWER/MODE selector is set to NORMAL, not CASIO CHORD or FINGERED. * Finally, if you've selected Tone '99 PERCUSSION', remember that only keys with percussion instrument illustrations will produce sound.
