What to do if my Yamaha PSR-E443 Electronic Keyboard volume is too soft or the sound quality is poor?

If the volume is too soft, the sound quality is poor, the Style/Pattern/Song/Arpeggio stops unexpectedly or will not play, the recorded data of the song does not play correctly, or the LCD display suddenly goes dark and all panel settings are reset, the batteries may be low or dead. Replace all six batteries with completely new or completely recharged ones, or use the AC power adapter.
