      If you're not getting any sound from your RockJam Keyboard when you press the keys, here are a few things to check: * Make sure the master volume is turned up to a suitable level. * Ensure that headphones or other external equipment aren't plugged in, as they'll automatically disable the built-in speakers. * Verify that fingered chord mode isn't active, as incorrect key presses in this mode won't produce sound. * Confirm that the volume isn't set to the lowest level (muted).

      If the sound from your RockJam Keyboard is distorted or interrupted, and the keyboard isn't working as expected, it might be due to the power adapter. Try using the power adapter that came with your keyboard. Alternatively, the batteries may need replacing.
