Connect to a PC
When using the set with a PC for calls, open the SG189 glasses from the folded position to power on the glasses and plug the USB dongle into the USB port of your PC, and they will auto pair with each other.
After they're paired, please check your PC's sound settings and make sure that the "Avantree" is chosen as the audio input and output device on your PC, as well as in the meeting software:
Please note that there are no volume buttons on the glasses. If you need to adjust the volume level, you can use the volume control on your PC or smartphone.
