Why is the volume so low on my Yamaha Musical Instrument?

  If the overall volume of your Yamaha Musical Instrument is too low, or there is no sound at all, first, raise the [MASTER VOLUME] dial. If that doesn't work, move the [SONG BALANCE] slider toward the keyboard to increase the keyboard volume. Also, ensure headphones are disconnected if the Speaker setting is set to “Normal HeadphoneSW”. Check that the speaker setting is set to “Normal” or “ON”. Verify that Local Control is ON. Finally, make sure “Expression” is not assigned to the right pedal or the AUX pedal; if it is, assign another function to the pedal.
