Adjust the microphone

The microphone boom rotates up to 270 degrees. Rotate the boom to position the microphone on either the right or left side. A diagram shows the microphone boom rotating up to 270 degrees around its base, with microphone icons indicating placement options on the left or right side.

Note: The microphone boom supports the flip-to-mute function. Flip up or down the microphone boom to mute or unmute. When the microphone is muted, the LED light on the end of the boom is solid red (?). When it is unmuted, the light is off.

The headset can play audio from other devices, such as smartphones, tablets, and notebook computers.

Pairing via USB-A Bluetooth audio receiver

Chapter 3. Troubleshooting

Common Issues and Solutions

1. What should I do if the headset speaker does not work in the Microsoft Teams meeting?

   • If the headset is connected to the computer via Bluetooth, go to Microsoft Teams audio settings and select "Lenovo Wireless VoIP Headset Hands-Free AG Audio" for the speaker.
   • If the headset is connected to the computer via the USB-A Bluetooth audio receiver, do one of the following:
     • Re-plug the receiver.
     • Restart the Microsoft Teams app.

   Note: The above solution also applies if it is the headset microphone that is not working.

     • Disconnect the Bluetooth connection directly.
     • Go to Microsoft Teams audio settings and select "Lenovo Wireless VoIP Headset-Receiver or Headset (Lenovo Wireless VoIP Headset Hands-Free AG Audio) (Bluetooth)" for both the microphone and speaker.

   Note: It is not recommended to connect the headset to the computer using both Bluetooth and the receiver at the same time.

   There may be a delay in some computers recognizing your headset after you switch the device. You can check the headset in your computer's list of Bluetooth devices to see if the new headset is connected.

3. What should I do if the button controls are not synchronized with the Microsoft Teams app after connecting to the computer via the receiver?

   Try restarting the Microsoft Teams app.
