2. Setup and Pairing
Follow these steps to set up and pair your Plantronics BT300-MOC Bluetooth USB Adapter with your compatible Plantronics headset.
- Insert the Adapter: Plug the Plantronics BT300-MOC USB Adapter into an available USB port on your computer. The adapter's LED indicator will typically flash to show it is powered on and ready for pairing.
- Automatic Driver Installation: Your computer's operating system should automatically detect and install the necessary drivers for the adapter. This process may take a few moments.
- Prepare Headset for Pairing: Put your Plantronics Bluetooth headset into pairing mode. Refer to your headset's specific user manual for instructions on how to activate pairing mode. This usually involves holding down a button until an LED flashes or an audio prompt indicates pairing mode.
- Pairing Process: Once both the adapter and headset are in pairing mode, they should automatically detect each other and establish a connection. The adapter's LED will typically change to a solid light (or a different flashing pattern) to indicate a successful connection.
- Configure Audio Settings: After successful pairing, you may need to select the Plantronics headset as the default audio input and output device in your computer's sound settings or within your communication application (e.g., Skype for Business, Microsoft Teams).
3. Operating Instructions
Once paired, the BT300-MOC adapter facilitates communication between your headset and computer applications.
- PC Communication: Use your paired Plantronics headset for audio with PC-based communication applications such as Skype for Business, Microsoft Office Communicator, or other VoIP software.
- Multipoint Connectivity: If your Plantronics headset supports multipoint connections, you can maintain a connection to both your computer (via the BT300-MOC) and a mobile device simultaneously. This allows you to switch between PC calls and mobile calls without re-pairing.
- Audio Control: Volume and mute functions are typically controlled directly from your Plantronics headset or through the software application on your computer.
4. Maintenance
To ensure the longevity and optimal performance of your Plantronics BT300-MOC Bluetooth USB Adapter, consider the following maintenance guidelines:
- Storage: When not in use, store the adapter in a safe place to prevent physical damage. Avoid leaving it plugged into a laptop during travel if there is a risk of impact.
