Troubleshooting
If you have problems with the unit, here are a few troubleshooting tips. If you cannot solve the problem easily
yourself, consult your Yamaha piano dealer. DO NOT attempt to repair the piano or the AC adaptor yourself.
Symptom
Cause
Remedy
The unit does not turn on.
The AC adaptor may not be plugged in
correctly.
Insert the AC adaptor firmly into the
DC12V or DC IN 12V jack and AC
outlet (page 9).
The unit turns on but no sound is heard.
The VOLUME knob may be turned to
the far left position.
Adjust the setting to an optimal level
(page 11).
The voice is set to Off.
The pedal has no effect.
The pedal sensor may not be connected
correctly.
Connect the cable firmly to the SENSOR
jacks on the rear of the control unit.
The acoustic piano emits sound when I
am using the Silent Piano™ function to
play.
Playing with extreme force may result in
sound being emitted from the acoustic
piano.
Moderate the strength of your playing.
The balance or volume varies when
listening through commercially available
headphones.
Headphone properties differ depending
on their type, so different headphones
may have different balance or volume
characteristics.
Use the same type of headphones for
optimum performance.
I can hear a rattling sound from the
piano body when playing with the Silent
Piano™ function.
This is not a fault. This is the sound of
the acoustic piano’s keystroke.
When I play a rapid series of notes
with the Silent Piano™ function, a loud
sound is emitted that is not part of the
performance.
This is not a fault. The structure of the
Silent Piano™ causes this to occur in
some cases.
No reverb effect is applied to the sound.
The reverb depth may be set to 0.
Increase the reverb depth to apply an
appropriate amount of reverb (page
14).
The sound lingers excessively.
The reverb depth or the Damper
Resonance effect depth may be set to an
excessive level.
Set these parameters to an appropriate
level (pages 14 and 42).
Noise is heard from the headphones or
speakers.
The noise may be due to interference
caused by the use of a mobile phone in
close proximity to the unit.
Turn the mobile phone off, or use it away
from the unit.
The headphones or speakers may not be
connected correctly.
Connect the headphones or speakers to
the corresponding jacks firmly (page
11 or 37).
The pitch of the unit is different to that of
other instruments.
The pitch is different depending on the
instrument.
You can adjust the pitch of this unit to
match that of other instruments (page
38).
