Uses

• Bluetooth is most typically used to connect hands-free devices such as speakerphones and headsets to mobile phones. Headsets, speakerphones, GPS units and some car stereos are Bluetooth-compatible, meaning that you can use them as a hands-free device for your phone and talk through them rather than through your handset. Bluetooth can also be used to connect your phone to your computer (to transmit contacts or other data), and is used in some home theater systems to transmit files between devices.
  
  

Pairing

• You need to pair two Bluetooth devices together in order for them to communicate with each other. Every Bluetooth device has its own unique ID "pairing code." When using your phone, you would typically have your phone "search for new devices" and find the headset or the Bluetooth-capable device you would like to use with it. Once your phone has located the device you will be prompted to enter its pairing code (typically found on a sticker on the back of your headset or speakerphone) in order to join the two together. Once two devices have been paired you should be able to use them together for the duration of their lives without having to complete the pairing process again.
  
  

Range

• Try to keep the two Bluetooth devices you are using as close to each other as possible. Most devices only have a communication range of around 10 feet. If you are using a Bluetooth headset and walk too far away from your cell phone you might experience static in your call or even drop the call entirely. Typically the closer you can keep the two devices together, the better the connection between the two devices will be.
