What to do if the display turns off and settings reset on my Yamaha PortaTone EZ-30 Electronic Keyboard?

If the display on your Yamaha Electronic Keyboard suddenly turns off and the panel settings are reset, it probably means the battery voltage is low. Replace all six batteries with new ones, or use the AC adapter.
