Troubleshooting
If this instrument is not operating as expected, check the following points.
The instrument will not turn on.
Is the AC adapter plug connected to the AC outlet? Have you pressed the power button?
The power will not go off.
Did you hold down the power button for a while?
The power turns off by itself.
The auto poweroff function may be enabled.
No sound is heard from the speakers of this instrument when the keys are played.
Is the instrument’s volume turned up? Is a pair of headphones connected to this instrument?
The speakers will not produce sound when headphones are connected to this instrument. The part buttons might all be muted. Is the volume down on the pedal connected to the FOOT CONTROLLER jack? If sound is not heard when pressing some keys, you may have exceeded the instrument’s maximum polyphony. The local control in the SETTING functions should be set to “On”. Are the speakers set to off? Press the SPEAKER EQ/[SPEAKER OFF] button while holding down the [SHIFT] button. The keyboard parts might all be muted.
The sound will not stop.
The functions or polarity for the pedal might not be set correctly.
The sound seems to be doubled.
If you are using a DAW, make sure that the local control setting in the SETTING functions is set to “Off”.
The sound coming from external audio equipment is distorted.
The inputs of the powered monitor speakers and other equipment might be overloaded. Adjust the volume on this instrument using the VOLUME knob.
The pitch is off.
Is the transpose function set correctly? Has “MasterTuning” in the SETTING functions been set
correctly, as well as the program’s octave and tune edit parameters? Is the scale set correctly? See “UpperScaleTyp” (page 22) and “StyleScaleTyp” (page 22) for these settings in the SETTING functions. The quarter tone settings may be enabled. Check the “Pedal Function” (page 22) in the SETTING functions.

29 Appendix
I hear unwanted noise.
When the volume for a part is raised, the digital signal processing may overload the signal, which could cause distortion or other noises. This is not a malfunction. Try lowering the volume on each part button.
You may hear distorted or noisy sounds due to input overload with certain effects. This is not a malfunction.
In certain electrical environments, you may hear noise due to a ground loop or other factors.
The pedal switch or expression pedal connected to the FOOT CONTROLLER jack doesn’t work like it should.
The functions or polarity for the pedal might not be set correctly. See “Pedal Function” (page 22) and “Pedal Polarity” (page 22) for these settings in the SETTING functions.
Is the variable range of the expression pedal set correctly? Calibrate as shown on “Calibrating an expression pedal” (page 28).
I cannot record a user song.
The maximum number of user songs is 999. You may need to delete one (see page 20 “Deleting a user song”.)
MIDI signals sent to/from this instrument and a computer are not being correctly received.
Is the USB cable connected correctly to the USB TO HOST port?
The instrument does not let me access the MEDIA functions.
Is your USB flash drive correctly plugged in? If the USB flash drive is correctly plugged in, you should see in the display.
