Turn off the "Fingered Chord" setting. With Fingered chord, keyboards make sounds only when playing the chord properly.The area of chord keyboard is the left of the split point (refer to the user's manual).

If you can't transfer songs, USB isn't recognised, or MIDI USB device won't install, please follow the following steps:

1. Configure USB MIDI device first. Connect USB midi cable/device you have. Insert accompanying CD and complete installation of that device before connecting to keyboard.
2. Connect the OUT to the IN on the keyboard. Connect the IN to the OUT on the keyboard (This may be different depending on the MIDI device being used. Please see the MIDI device instructions for proper connection.)
3. Configure MIDI IN and MIDI OUT on the computer MIDI software. These must both be the same and named for the device/cable you installed. No matter what software is used MIDI IN and OUT MUST be configured in order to create connectivity between the software and the PC. THERE ARE NO EXCEPTIONS TO THIS RULE. If the customer does not know how to configure the MIDI IN and OUT with their Non-Casio software, they must contact their software vendor.
4. Once this is installed, almost EVERY MIDI software has some TEST mode.5) Make sure Local Control = ON on the keyboard itself.6) If keyboard is in sleep mode (Lighted Keys are playing by themselves with no sound), please hit a key and re-activate the keyboard before data transfer will work.

Check all connections, batteries, A/C cables, and verify that the power outlet is working.

If you are still having issues, please contact our service team.

If you are not using a CASIO brand sustain pedal, your pedal may have the opposite polarity. It will sustain when the pedal is not pressed, and remove the sustain during the pedal is pressed.If you use a CASIO sustain pedal, it will only sustain during pressed. Many current CASIO instruments (such as Privia models) can automatically detect the polarity of a sustain pedal.To ensure that the detection is correct on these models, firstly connect the pedal to the appropriate jack, then turn the keyboard on using the power button being sure not to touch the pedal.

Please check the following items:
-Is there any headphones or an adapter plug in the PHONES jacks?

PHONE jack
- Is the power switched on?
- Check whether the sound volume is the minimum position.
- If there is a speaker ON/OFF function, check whether the speaker is ON position.

If you are still having issues, please contact our service team.

Some models can play sound through headphones and speakers at the same time. Check whether the speaker output is OFF position when connecting to the PHONE jack.

Disconnect and reconnect the cable connecting the computer and instrument, and set up a device "CASIO USB-MIDI" on Music Production Software. For the device setting method, please contact the software development manufacturer.

Some models have the auto-power off function. The piano (or keyboard) will turn off automatically to preserve power after a period of inactivity. To disable the auto-power off function, please refer to the users manual.
If the power turns off automatically even if the auto-power off function is disabled, or the power turns off soon after the power turned on, there may be a failure.
