  If the overall volume of your Yamaha Musical Instrument is low, or no sound is heard, there might be several reasons. First, the Master Volume could be set too low, so adjust it to an appropriate level. Second, the digital piano’s speakers might be turned off, so turn them back on. Also, ensure that headphones or a conversion adapter are not connected to the headphones jack. Finally, verify that Local Control is ON.

  If the pedal of your Yamaha Musical Instrument isn't working, it might be due to an improperly connected pedal cable/plug. Ensure that you securely insert the pedal plug into the [SUSTAIN] or [PEDAL UNIT] jack.

  If moving the [MASTER VOLUME] slider doesn't change the volume of the headphones on your Yamaha Musical Instrument, check if you have set the external speaker volume to “Fixed”. If so, change the external speaker volume to “Variable.”

Why does my Yamaha Musical Instrument footswitch have the opposite effect?
- K
  Karla LeeAug 15, 2025
  If the footswitch on your Yamaha Musical Instrument seems to produce the opposite effect (pressing cuts off the sound, releasing sustains), the polarity of the footswitch may be reversed. This can happen if the footswitch was pressed when the power was turned on. To fix this, turn off the power and turn it on again to reset the function, making sure not to press the footswitch during power-up.
