No sound, or people can't hear you
- Check the mute button or mute light on the device and in the app.
- In Teams, Zoom or your softphone, select this device as both microphone and speaker.
- For wireless models, make sure it's connected to the dongle or phone you think it is.
- Update the device firmware and the app.
Bluetooth or dongle won't pair
- Put the device in pairing mode and remove the old pairing from your phone or computer first.
- Plug the USB dongle directly into the computer, not a hub.
- Re-pair the dongle using the manufacturer's desktop app.
- Charge it fully: low battery can prevent pairing.
Keeps disconnecting or drops out
- Use wired Ethernet rather than Wi-Fi, and check the switch port for errors.
- Update firmware.
Won't turn on or status light is red/blinking
- Check the power adapter is the original one and firmly connected, and try another outlet.
- Unplug for 30 seconds and power it back on.
- Check the status light meaning in the user guide; a blinking light during startup or updates is often normal.
- If it never finishes starting, contact the manufacturer's support for a recovery.
