First, turn Bluetooth on by going to Wireless Manager.
Next, tap Settings > Bluetooth.
If you want your device to be discovered by another device, go to the Mode tab and check the box for "Make this device visible to other devices."
If you want to have your device discover other available Bluetooth enabled devices, on the Devices tab, tap "Add New device."
Make sure that the other device is set to discoverable mode.
Once your device finds the other device, highlight the device you want to pair with and tap Next. The device will then ask you for a passkey. Enter in a short passkey of your choice and tap Next. The device that you are trying to pair with will ask for that passkey to be entered. Once the passkey has been accepted you will be taken to a screen where you can choose a "Display Name" for that device and the services that it will be used for then tap Finish. Once this is done, the devices are paired.
