Troubleshooting
Overall
A click or pop is heard when the power is turned on or o. This is normal. Electrical current is being applied to the instrument.
The power is automatically turned o. This is normal and due to the Auto Power O function. If necessary, set the
parameter of the Auto Power O function (page24).
Noise is heard from the instrument. Noise may be heard if a mobile phone is used near the instrument or if the
phone is ringing. Turn o the mobile phone, or use it further away from the
instrument.
Noise is heard from the instrument’s speakers or
headphones when using the instrument with an iPhone/
iPad app.
When you use the instrument along with an iPhone/iPad app, we recommend
that you set “Airplane Mode” to “ON” on your iPhone/iPad in order to avoid
noise caused by communication.
In the LCD, there are some specic points that are always lit
or unlit.
These are the result of defective pixels and occasionally occur in TFT-LCDs; they
do not indicate a problem in operation.
There is a slight dierence in sound quality among dierent
notes played on the keyboard.
This is normal and is a result of the instrument’s sampling system.
Some Voices have a looping sound.
Some noise or vibrato is noticeable at higher pitches,
depending upon the Voice.
The overall volume is too low, or, no sound is heard. The master volume may be set too low. Set it to an appropriate level with the
[MASTER VOLUME] dial.
All keyboard parts are set to o. Use the PART ON/OFF [RIGHT 1]/[RIGHT 2]/
[RIGHT 3]/[LEFT] button to turn it on (page48).
The volume of individual parts may be set too low. Raise the volume in the
Mixer display (page90).
Make sure the desired channel is set to on in the Mixer display (page92).
Headphones are connected, disabling the speaker output. Unplug the
headphones.
Connect the footswitch to the appropriate jack.
Check whether the external speaker is connected and the volume control is
adjusted properly (pages 112, 124).
The sound is distorted or noisy. The volume may be turned up too high. Make sure all relevant volume settings
are appropriate.
This may be caused by certain eects or lter resonance settings. Check the
eect or lter settings and change them accordingly in the Mixer display,
referring to the Reference Manual on the website.
Not all simultaneously played notes sound. You are probably exceeding the maximum polyphony of the instrument. When
the maximum polyphony is exceeded, the least important notes (such as soft
notes and notes currently decaying) will stop sounding rst.
The keyboard volume is lower than the Style/ Song
playback volume.
The volume of the keyboard parts may be set too low. Raise the volume in the
Mixer display (page90).
The Main display does not appear even when turning the
power on.
This may occur if a USB ash drive has been installed to the instrument.
Installation of some USB ash drive may result a long interval between turning
the power on and appearance of the Home display. To avoid this, turn the
power on after disconnecting the device.
Some characters of the le/folder name are garbled. The language settings have been changed. Set the appropriate language for
the le/ folder names (page24).
An existing le is not shown. The le extension (.MID, etc.) may have been changed or deleted. Manually
rename the le, adding the appropriate extension, on a computer.
Data les with names of more than 50 characters cannot be handled by the
instrument. Rename the le, reducing the number of characters to 50 or less.
