- Reconnect the USB cable or dongle, straight into the computer.
- Check that the Speak2 75 is selected as the microphone and speaker in Teams, Zoom or Meet.
- Update the firmware. How
No sound or people can't hear you
- Check the device isn't muted (look for a red mute light).
- In the meeting app, select the Speak2 75 as both microphone and speaker.
- Check the volume on the device and on the computer.
- Move laptops and their fans away from the microphones.
Echo or feedback
- Make sure only one microphone and one speaker are active in the room: mute laptops that also joined the meeting.
- Don't run the room's audio through both the device and the TV speakers at the same time.
- Hard, bare rooms reflect sound. Rugs, curtains or acoustic panels reduce echo a lot.
- Update firmware: echo cancellation improvements often come in updates.
Keeps disconnecting or drops out
- Use the original cable or dongle and a direct port on the computer; long or cheap USB extensions cause dropouts.
- Turn off USB power saving on the computer (Windows: Device Manager → USB Root Hub → Power Management).
- Charge it: low battery causes Bluetooth dropouts.
- Update firmware and the meeting app.
Won't turn on or won't charge
- Charge it for at least 2–3 hours with the original cable.
- Try another USB port or charger.
- If the battery no longer holds a charge, contact the manufacturer about warranty service.
