What to do if Yamaha PSR-EW310 volume is too soft?

If your Yamaha musical instrument's volume is too soft, the sound quality is poor, the rhythm stops unexpectedly, recorded data doesn't play correctly, or the LCD display goes dark with settings reset, the batteries may be low or dead. Replace all six batteries with completely new ones, or use the included AC adapter.
