In order to pair you devices you have to:
1. Turn bluetooth on and put your BB in search mode
2. Headset must be in listen mode (usually when device is off you need to push and hold power button for about 5 seconds and the LED diode will start blinking)
3. Use 0000 (four zeros) as a pass code
If above procedure doesn't work, follow instructions from your manual
If manual won't work, stay on the line for the next available representative...
