Troubleshooting 
If you should experience difficulties with your stage piano, 
such as an inability to pr oduce sound or the output 
becoming distorted, work through the following checklists in 
order to rectify the situation. You may also be able to resolve 
any issues by executing the  Factory Set function (page 43) 
after first backing up your settings on a USB flash-memory 
device (page 39). If any specific problem should persist, 
however, please contact your Yamaha dealer or a service 
center (see the back of this booklet).
The stage piano produces no sound.
 Ensure that a stereo system, amplifiers, 
speakers, and/or headphones have been 
connected to the instrument.
Your stage piano does not come with built-in speakers. 
In order to hear the sounds that it produces, therefore, 
you will need to connect headphones or audio 
equipment such as amplifiers and speakers 
(page 16).
Ensure that the stage piano and the 
connected audio equipment are turned on.
 Ensure that the master volume on your stage 
piano and on the connected audio equipment 
are not set to an excessively low level.
If a foot controller has been connected to the 
instrument, try using it  to increase the volume.
Ensure that your stage piano has been 
correctly connected to the other audio 
equipment.
 Ensure that local control has not been turned 
off.
If local control is turned of f and your stage piano is not 
being used together with a computer or another 
device that returns MIDI messages, it will not be 
possible to produce any sound from the internal tone 
generator by playing the keyboard. 
• Press [UTILITY]; select  02: MIDI and press [ENTER]; 
set LocalSw  to “on”.
Ensure that no Part volumes have been set to 
an excessively low level.
• Select Volume using [SLIDER FUNCTION]; operate 
the Part sliders.
 Ensure that Part buttons are not turned off.
A Part will not produce any sound when its button is 
turned off (i.e., its light is not lit). If a required Part is off, 
press its Part button and verify that it lights up.
Review your effect and filter settings and 
ensure that they are appropriate.
In particular, no sound will be produced at certain 
cutoff-frequency settings when using a filter. 
• Select the Part in question; press [EDIT]; select 
02: Part  and press [ENTER]; select  02: Filter/EG and 
press [ENTER]; change the  Cutoff setting.
• Select the Part in question; press [EDIT]; select  02: Part  and press [ENTER]; select each of 
03: Effect-A  and 04: Effect-B  and press [ENTER]; 
change settings as appropriate.
Sound input via the [AUX IN] jack cannot 
be heard.
 Ensure that the volume on the connected 
audio equipment has not been turned fully 
down.
Audio files cannot be heard when 
played.
Ensure that the volume for playback of audio 
files has not been turned fully down.
• Press [UTILITY]; select  01: General and press 
[ENTER]; increase the  Vo l u m e setting on the Audio 
Playback screen.
A sound continues to  play without end.

connected USB flash-memory device, press 
the [ +] (Stop) button.
The stage piano turned off unexpectedly.

is enabled.
If necessary, either turn it of f or change the time until it 
is activated.
• Press [UTILITY]; select  01: General and press 
[ENTER]; set  AutoOff to “off” or a different time.
The output from the stage piano sounds 
distorted.

appropriately.
Sound can be distorted with certain combinations of 
effect type and pa rameter settings. 
• Select the Part in question; press [EDIT]; select  02: Part  and press [ENTER]; select each of 
03: Effect-A  and 04: Effect-B  and press [ENTER];

which your stage piano is  connected. If lowering the 
input gain or pressing the corresponding pad button 
does not remove the distortion, try lowering the stage 
piano’s output volume.

simultaneously.
If the total number of notes being played by all Parts is 
too high, the stage piano’s output may become 
intermittent and stuttered. 
Only one note can be played at any time.
Ensure that the playing mode is not set to 
“mono” .
If you wish to play multiple  notes at the same time, the 
playing mode for the Part(s ) must be set to “poly”.

corresponding effect will not be  heard. To remedy this 
situation, press the button in question and verify that it 
lights up.
 In the event that the chorus and/or reverb 
effect cannot be heard, ensure that the chorus 
and reverb send levels are not set excessively 
low.
• Select Chorus or Reverb using [SLIDER 
FUNCTION]; operate the Part sliders.
 In the event that insertion effects cannot be

settings are changed as a result of Part 
sliders being operated or the stage piano’s 
internal tone generator being controlled by 
another MIDI device.
Audio playback does not start when the 
[3 ] (Play) button is pressed.
