5. Maintenance
- **Battery Care**: The tuner uses a Li-Po battery. To maximize battery life, charge it before initial use. If the device will not be used for an extended period (e.g., more than 3 months), charge it at least once every 3 months to maintain battery health.
- **Cleaning**: Use a soft, dry cloth to clean the tuner. Do not use abrasive cleaners or solvents.
- **Storage**: Store the tuner in a cool, dry place away from direct sunlight and extreme temperatures.
6. Troubleshooting

- **Inaccurate tuning**:
- Verify the correct tuning mode (Chromatic, Guitar, Violin, Ukulele) is selected for your instrument.
- Ensure the tuner is securely clipped to the headstock. The piezo sensor relies on vibrations from the instrument.
- Tune in a quiet environment to minimize external noise interference.
- **Display is dim or unresponsive**: Recharge the battery. If the issue persists after charging, contact customer support.
