Troubleshooting
If you have problems with your Silent Piano™, 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.
The unit is turned on but does not emit sound.
• The AC adaptor may not be plugged in correctly. Insert
the AC adaptor firmly into the DC IN 16V jack and AC
outlet.
• The [VOLUME] control may be turned to the far left
position. Adjust the setting to an optimal level. The unit
outputs standard volume when the volume control is
set to the 3 o’clock position.
The power is automatically turned off.
• This is normal and due to the Auto Power Off function.
If necessary, disable the Auto Power Off function
(page 15).
The acoustic piano emits sound when I am
playing with the Silent Piano™ function active.
• Playing with extreme force may result in sound being
emitted from the acoustic piano. Please moderate the
strength of your playing.
The balance varies when listening through
commercially available headphones.
• Headphone properties differ depending on their type,
so different headphones may have different balance
characteristics.

characteristics.
I can hear a rattling sound from the piano body
when using it in Silent Piano™ mode.
• This is not a fault. This is the sound of the acoustic
piano’s keystroke.
When I play a rapid series of notes in Silent
Piano™ mode, 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 minimum. Adjust the
depth to apply an appropriate amount of Reverb
(page 36).
The sound lingers excessively.
• The Reverb depth may be set to an excessive level.
Adjust the Reverb depth to an appropriate level
(page 36).
The pitch of this instrument is different from that
of other instruments.
• You can adjust the pitch of this unit to match that of
other instruments (page 34).
The connected USB flash drive does not respond.
• Disconnect the USB flash drive from the unit and then
connect it again. If it still does not respond, it may be
damaged.
• Check if your USB flash drive is supported on this unit
(page 25).
The Song saved in the USB flash drive cannot be
played back.
• This unit can play only the latest recorded Song in the
USB flash drive. If you want to play the Songs recorded
previously, use an external audio device such as a
computer or a portable music player.
Sound input to the [AUX IN] jack is interrupted.
• The Noise Gate function is activated (page 38). Increase
the output volume of the external device connected to
the [AUX IN] jack, or set the Noise Gate to off.
No Sostenuto effect is applied when the sostenuto
pedal is pressed.
• The Sostenuto effect cannot be applied when the Silent
Piano function is active.
