Nokia Mono Bluetooth Headset BH-102 - How do I establish the Bluetooth connection between the compatible mobile device and the Nokia Bluetooth Headset?

When the connection is created for the first time, you must enter the Bluetooth pairing passcode 0000 (found also in the user guide) into the device. Up to seven devices can be paired with the Nokia Bluetooth Headset. The last or most recent pairing is the active one. When all seven places are full, the oldest pairing is replaced by the new pairing.
