Installation Steps

1. Install any instant messaging software on your computer (e.g., Tencent Meeting, SKYPE, MSN, etc.).
2. Connect one end of the USB cable to the Type-C USB port on the side of the conference microphone, and the other end to your computer's USB port.
3. After connecting the USB data cable normally, the three indicator lights in the center of the conference microphone will light up blue and remain solid.
4. After completing software and hardware installation, you can start using the conference microphone.

PC Volume Adjustment Notes

The conference microphone is compatible with various PCs and Macs. Due to varying default system volume settings, it is recommended to adjust your computer's conference microphone playback volume to a medium-high level for optimal call quality. Setting the volume too high may lead to distorted speaker sound.

Caution:

• Do not connect multiple conference microphones, including this device, to your computer simultaneously.
• Connect this device directly to your computer. Using a USB hub may cause operational issues.
• Audio duplication may be interrupted based on the computer's load or available memory.
