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 socket 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 lamp lights but the instrument does not emit any sound, and the pedal has no
effect.
- The key sensor or the pedal sensor on the rear panel of the control box may not be connected correctly. Insert
the KEY and PDL plugs firm into their respective jacks on the control box (labeled KEY and PDL on the
bottom of the control box).
☞
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. 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.
☞
The volume varies when listening through commercially available headphones.
- Headphone properties differ depending on their type, so different headphones may have different volume
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 control may be set to the extreme left. Rotate the knob to the right to apply an appropriate
amount of reverb.
☞
The sound lingers excessively (There is too much reverb applied to the sound).
- The reverb and DDE may be set at an excessive level. Set these parameters to an appropriate level (see pages 7
and 8).
☞
The pitch of this instrument is different to that of other instruments.
- You can adjust the pitch of this unit to match that of other instruments (see page 7).
☞
Panel buttons are lit when I am not playing or recording.
- The buttons light dimly when USB memory is connected in the USB terminal (see pages 11 and 12).
