What to do if keys on my Casio Casiotone CT-S410 Synthesizer aren't working?

If nothing happens when you press a key on your Casio Synthesizer, first, adjust the volume level. Next, make sure nothing is plugged into the PHONES/OUTPUT jack on the back. Finally, try turning the keyboard off and then back on to initialize the settings.
