Bluetooth headsets allow you to make and receive calls on your mobile phone without using your hands. Hands-free calling isn’t just convenient. In many states, it’s illegal to talk on your phone while driving unless you are using a hands-free headset such as the Plantronics Explorer 340. The Explorer 340 connects with (or “pairs” with) any mobile phone that allows Bluetooth connections.

Skill level:


  1. 1

    Turn on the Bluetooth feature on your mobile phone to allow it to search for Bluetooth signals within range of the phone.

  2. 2

    Hold down the call button on your Plantronics 340 until the headset flashes blue and red lights.

  3. 3

    Select the Plantronics 340 headset in the list of Bluetooth devices within range. Click “Next.”

  4. 4

    Enter the passkey as “0000.” Click “Next.” Use your Plantronics 340 headset as desired when it flashes blue to indicate the pairing is successful.

Tips and warnings

  • In most cases, you only have to pair the Plantronics Explorer 340 with your phone once.
  • These instructions can vary slightly depending on the model of mobile phone you use. Consult your phone’s user manual if you have questions regarding how to set up a Bluetooth connection with your specific model.
