What to do if my Yamaha PortaTone PSR-510 volume is reduced or has poor sound quality?

If you experience reduced volume, poor sound quality, improper demo or song memory playback, or the MULTI DISPLAY has gone out with the panel setting set to default on your Yamaha Electronic Keyboard, the batteries probably need to be replaced. Replace all six batteries with new ones of the same type.
