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

The unit turns on but no sound is heard.
The pedal has no effect.
The acoustic piano emits sound when I
am using the Silent Piano™ function to
play.
The balance or volume varies when
listening through commercially available
headphones.
I can hear a rattling sound from the
piano body when playing with the Silent
Piano™ function.
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.

Noise is heard from the headphones or
speakers.

other instruments.

Cause
The AC adaptor may not be plugged in
correctly.
The VOLUME knob may be turned to
the far left position.
The voice is set to Off.
The pedal sensor may not be connected
correctly.
Playing with extreme force may result in
sound being emitted from the acoustic
piano.
Headphone properties differ depending
on their type, so different headphones
may have different balance or volume
characteristics.
This is not a fault. This is the sound of
the acoustic piano's keystroke.
This is not a fault. The structure of the
Silent Piano™ causes this to occur in
some cases.
The reverb depth may be set to 0.
The reverb depth or the Damper
Resonance effect depth may be set to an
excessive level.
The noise may be due to interference
caused by the use of a mobile phone in
close proximity to the unit.
The headphones or speakers may not be
connected correctly.
The pitch is different depending on the
instrument.
Remedy
Insert the AC adaptor firmly into the
DC12V or DC IN 12V jack and AC
outlet (page 9).
Adjust the setting to an optimal level
(page 11).
Select the voice (page 12).
Connect the cable firmly to the SENSOR
jacks on the rear of the control unit.
Moderate the strength of your playing.
Use the same type of headphones for
optimum performance.
Increase the reverb depth to apply an
appropriate amount of reverb (page
14).
Set these parameters to an appropriate
level (pages 14 and 42).
Turn the mobile phone off, or use it away
from the unit.
Connect the headphones or speakers to
the corresponding jacks firmly (page
11 or 37).
You can adjust the pitch of this unit to
match that of other instruments (page
38).
