 Compatibility: works with supported Yealink phones and standard Windows/macOS computers when supported by device firmware or drivers

How to use
Insert the Yealink BT51-C into an available USB-A port on a compatible Yealink phone or computer. Allow the host device to recognize the adapter and install any required drivers or firmware updates if prompted. Activate pairing mode on the BT51-C following the vendor instructions, then place the Bluetooth headset into pairing mode to establish the connection. Once paired, select the headset as the audio device in the phone or computer audio settings and verify call audio and microphone operation.
Usage recommendations
Place the dongle in a USB port with direct line of sight to the headset for optimal range. Keep the headset firmware up to date and follow Yealink guidance on compatibility to ensure consistent audio quality.
