      If your ROCK JAM Electronic Keyboard isn't producing sound when you press the keys, first ensure the master volume is appropriately adjusted. Also, check if headphones or other external equipment are plugged in, as they automatically disable the built-in speakers.

      If the sound from your ROCK JAM Electronic Keyboard is distorted or interrupted, and the keyboard isn't functioning correctly, the issue might stem from an incorrect power adapter. Try using the power adapter that was supplied with the keyboard. Alternatively, the batteries might need replacing.

    Why doesn't auto accompaniment work on my ROCK JAM RJ-661?
    • J
      Jamie LopezAug 28, 2025
      If the auto accompaniment feature isn't working in SYNC status on your ROCK JAM Electronic Keyboard, ensure that either Single Finger or Fingered mode is selected. Then, play a note using the first 19 keys on the left side of the keyboard.
