5. Maintenance

To maintain your digital piano in optimal condition:

• Cleaning: Use a soft, dry cloth to wipe down the keys and surfaces. Avoid abrasive cleaners or solvents.
• Dust Protection: Cover the keyboard with a dust cover when not in use to prevent dust accumulation.
• Environmental Conditions: Keep the piano away from direct sunlight, extreme temperatures, and high humidity to prevent damage to the wood and electronic components.
• Handling: When moving the piano, ensure it is lifted carefully by two people to avoid damage to the legs or main unit.

6. Troubleshooting

If you encounter issues with your digital piano, consider the following common solutions:

• No Sound: Check if the power adapter is securely connected and the piano is turned on. Ensure the volume is not set to minimum. If headphones are plugged in, sound will only output through them.
• Keys Not Responding: Verify the piano is powered on. If specific keys are unresponsive, ensure no protective film or debris is obstructing them.
• Distorted Sound: Check the volume levels of both the piano and any connected external devices. Ensure all cables are securely connected.
• Connectivity Issues: For USB/MIDI connections, ensure the correct drivers (if required by your device) are installed and the application is properly configured to recognize the piano.
