How to resolve abnormal sound issues with the Poseidon M30 subwoofer?

1. Please perform a factory reset: Press and hold the "Device Reset" button on the remote control for 5 seconds to reset the device.

2. Please optimize the environment and placement; ensure there are no obstacles between the subwoofer and the main unit.

3. Maintain a reasonable distance (5 meters or less is recommended) and avoid placing the unit near routers, microwave ovens, or other high-power appliances that may cause interference.

4. Test using different audio/video files and check the audio source to confirm whether the issue originates from the source itself.

5. Try switching between different connection methods (e.g., HDMI, Optical, Bluetooth) for comparison.

6. Open the Ultimea app to check for software updates. Test the device again after updating to the latest version.

7. Place the subwoofer securely on the floor, ensuring that there are no surrounding obstacles blocking it. When testing, set the subwoofer volume level to 0–3.
