Note whether your BlueTooth is "On" or "Off" at the top of the screen. (The button filled in with blue is the active button.)

Next, tap the Setup Devices button at the bottom of the screen:

To see what devices have already been paired with your phone, tap the Trusted Devices button.

The following screen displays, showing which devices have already been paired with the phone. Pairing a device sets it up as a trusted device. Tap Done.

Tap the Hands-Free setup button. This will walk you through pairing the device.

Tap the Next button.

The phone will start searching for the device. Be sure to read the BlueTooth device's manual to learn how to make the device "discoverable" for pairing. This varies depending on the device.

The phone will search for about 30 seconds. If the device is found, you may be prompted to enter a passkey. Read the device manual to find out what passkey to enter. After that, your device is paired with your phone and ready to use.
