5. Maintenance
To ensure the longevity and optimal performance of your STUDIOFINIX ceiling speakers, follow these simple maintenance guidelines:

- Grille Care: The speaker grilles are removable and paintable. If you choose to paint them, ensure the paint is applied thinly and evenly to avoid clogging the perforations, which could affect sound quality. Allow paint to dry completely before reattaching.
- Environment: Keep the speakers and amplifier in a dry environment, away from excessive moisture, direct sunlight, and extreme temperatures.
- Cable Management: Periodically check speaker wire connections to ensure they are secure and free from damage.

- Check if the power outlet is functional by plugging in another device. - No Sound:
- Verify that the amplifier is powered on and the volume is turned up.
- Check all speaker wire connections for correct polarity and secure fit.
- Ensure the correct input mode (Bluetooth, AUX, USB, MIC) is selected on the amplifier.
- If using Bluetooth, confirm your device is successfully paired and the volume on your device is also turned up. - Bluetooth Disconnection/Poor Range:
- Ensure your mobile device is within the 100 ft unobstructed range of the amplifier.
- Avoid physical obstructions (walls, large furniture) between your device and the amplifier.
- Try unpairing and re-pairing the Bluetooth connection on your device. - Distorted Sound:
- Reduce the volume on both the amplifier and your audio source.
- Check speaker wire connections for any loose strands or short circuits.
