This means that while you can do a lot with your Casio keyboard, a lot can also go wrong too. Troubleshoot your Casio keyboard with some basic interventions.

    No Keyboard Sound

  1. 1

    Tighten the AC adaptor plugs going into the keyboard and electrical socket. Check for cracked or damaged AC wire that will prevent electrical current from going to the keyboard.

  2. 2

    Make sure the batteries are inserted correctly if you are using them instead of an AC adaptor. Keyboard batteries run down quickly even if you do not use the keyboard, so make sure the batteries still have a charge.

  3. 3

    Turn the power "Off" and "On." Move the volume control up midway, if it is all the way to the left, to raise the sound level.

  4. 4

    Switch the Mode setting to "Normal." "Fingered Mode" will not play with single notes.

  5. 5

    Turn "Local Control" on to get the Casio keyboard to play sound through its speakers.

    No Touch Response

  1. 1

    Turn the keyboard "On" and "Off."

  2. 2

    Push the "Touch Response" button to restore keyboard volume response to variable pressure from fingers.

  3. 3

    Repeat Steps 1 and 2 if pushing the "Touch Response" button does not restore keyboard touch sensitivity.

    MIDI Problems

  1. 1

    Show the "Sound Range Shift" screen by pressing "Transpose, Tune, MIDI" to correct the "Sound Range Shift" setting, which will play the correct MIDI notes from a computer when the keys on the keyboard are lit.

  2. 2

    Press "Transpose, Tune, MIDI" and set both the "Transpose" and "Tune" functions to the correct values to play the notes with another MIDI instrument.

  3. 3

    Turn off the "MIDI Thru" computer function or "Local Control" on the keyboard to prevent distorted or unusual sounds from the keyboard.

  4. 4

    Turn on "Accomp MIDI Out" on a computer to record chord accompaniment data on the computer from the keyboard.
