5. Operating Instructions

5.1 Initial Setup with Conferencing Software

After physical installation, configure your conferencing software to use the HDL300.

Open your preferred conferencing application (e.g., Zoom, Microsoft Teams, WebEx).
Navigate to the audio settings within the application.
Select "Nureva HDL300" as the microphone input device.
Select "Nureva HDL300" as the speaker output device.
Perform a test call to verify audio input and output.

5.2 Microphone Mist Technology

The HDL300 utilizes patented Microphone Mist technology, which creates thousands of virtual microphones throughout the room. This ensures that all participants are heard clearly, regardless of their position or movement within the meeting space.

5.3 Automatic Calibration

The system continuously self-calibrates to adapt to changes in room layout or furniture. This automatic adjustment optimizes microphone pickup zones and echo cancellation for consistent audio clarity.

6. Maintenance

Cleaning: Use a soft, dry cloth to clean the exterior of the HDL300 soundbar. Do not use liquid cleaners or abrasive materials.
Firmware Updates: Regularly check for firmware updates through the Nureva Console software to ensure optimal performance and access to new features. Updates are typically managed remotely via the cloud-based Nureva Console.
Environmental Conditions: Ensure the device is operated within recommended temperature and humidity ranges to prevent damage.

7. Troubleshooting

Problem	Possible Cause	Solution
No audio output from HDL300 speakers.	Incorrect audio output device selected in conferencing software. Volume too low. Cables not properly connected.	Verify "Nureva HDL300" is selected as the speaker in your application's audio settings. Increase volume on your computer and within the conferencing application. Check all cable connections, especially the USB-B and Ethernet cables to the Connect Module.
Participants cannot hear me.	Incorrect microphone input device selected. Microphone muted. Connect Module not powered.	Verify "Nureva HDL300" is selected as the microphone in your application's audio settings. Ensure the microphone is not muted in the conferencing application or on your computer. Check that the Connect Module's power supply is securely connected and plugged in.
Audio quality is poor or distorted.	Interference from other devices. Outdated firmware. Room acoustics issues.	Ensure the HDL300 is not placed too close to other electronic devices that may cause interference. Check for and install any available firmware updates via Nureva Console. While Microphone Mist technology adapts, extreme room acoustics (e.g., very reverberant spaces) can impact performance. Consider acoustic treatments if issues persist.
