Connect your Jabra BT135 headset to other Bluetooth-compatible devices to use the headset wirelessly. Before you can tap into the BT135's Bluetooth features, you need to pair it to the device with which you want to use it. How you go about pairing the headset varies depending on whether you're connecting it to a mobile device or a computer.
