hold the bluetooth on button while the phone is in pairing mode this is how it finds it and if it asks for a pin at the end

ok this is simple they dont put it in the books but i found out going to the techs.
when it gets to the pin type in 0000
1234 or 12345
i dont know why they dont put these in

First Switch on the blutooth in mobile, then switch on the Blutooth device. The phone may ask for setting up the device automatically (for first try only). If failed to connect the follow the following steps.

Please note that the LED in blutooth device has to flash green and red alternately for connecting to phone blutooth. If not press both the volume controls in device continuosly for few seconds so that the LED will start blinking red and green alternately. Now the device is ready for connecting. When the phone asks for pass code press "0000" (zero for 4 times) and press ok or accept.

I think this will help you for sure.
