Troubleshooting
Troubleshooting
Overall
A click or pop is heard when the power is
turned on or off.
This is normal. Electrical current is being applied to the instrument.
The power is automatically turned off. This is normal and due to the Auto Power Off function. If necessary, set the parameter of
the Auto Power Off function (page 21).
Noise is heard from the instrument. Noise may be heard if a mobile phone is used near the instrument or if the phone is ring-
ing. Turn off the mobile phone, or use it further away from the instrument.
Noise is heard from the instrument’s speak-
ers or headphones when using the instru-
ment 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 communi-
cation.
In the LCD, there are some specific 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 difference in sound quality
among different notes played on the key-
board.
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 off. Use the PART ON/OFF [RIGHT 1]/[RIGHT 2]/[RIGHT 3]/
[LEFT] button to turn it on (page 44).
The volume of individual parts may be set too low. Raise the volume in the Mixer display
(page 80).
Make sure the desired channel is set to on in the Mixer display (page 82).
Headphones are connected, disabling the speaker output. Unplug the headphones.
Connect the footswitch to the appropriate jack.
Make sure that the Speaker setting is set to “On” or “Headphone switch”: [MENU] [Util-
ity]
The sound is distorted or noisy. The volume may be turned up too high. Make sure all relevant volume settings are appro-
priate.
This may be caused by certain effects or filter resonance settings. Check the effect or filter
settings and change them accordingly in the Mixer display, referring to the Reference Man-
ual on the website.
Sound from the speaker is occasionally inter-
rupted.
The sound level is too high, so the speaker protection function is activated and the sound
stops. Set the sound to an appropriate level by turning down the [MASTER VOLUME] dial.
Not all simultaneously played notes sound. You are probably exceeding the maximum polyphony of the instrument. When the maxi-
mum polyphony is exceeded, the least important notes (such as soft notes and notes cur-
rently decaying) will stop sounding first.
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 dis-
play (page 80).
The Main display does not appear even
when turning the power on.
This may occur if a USB flash drive has been installed to the instrument. Installation of
some USB flash 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 file/folder name are
garbled.
The language settings have been changed. Set the appropriate language for the file/ folder
names (page 21).
An existing file is not shown. The file extension (.MID, etc.) may have been changed or deleted. Manually rename the
file, adding the appropriate extension, on a computer.
Data files with names of more than 50 characters cannot be handled by the instrument.
Rename the file, reducing the number of characters to 50 or less.
