To connect your Yamaha PSS-401 to external speakers, use a 1/4 inch audio cable. Plug one end into the headphone or line out jack on the keyboard and the other end into the input of your external speakers or amplifier.
Ensure the power adapter is properly connected to both the keyboard and a working power outlet. Check for any visible damage to the adapter or power cord. If using batteries, make sure they are inserted correctly and have sufficient charge.
To reset the Yamaha PSS-401 to its factory settings, turn off the keyboard, then hold down the highest key while turning it back on. This will restore the default settings.
Use a soft, damp cloth with a mild detergent to gently clean the keys. Avoid using excessive water or harsh chemicals to prevent damage to the keyboard.

To change the voice settings, press the 'Voice' button on the keyboard, then use the number keys to enter the desired voice number from the user manual.
Sticky keys can often be resolved by cleaning. Power off the keyboard and carefully clean around the sticky keys with a damp cloth. If the issue remains, you may need to consult a professional technician.
