supertooth II, Bluetooth handsfree?

I have just bought a handsfree system for my car but it came without the charger and instructions. I have acquired a charger for it but so far been unlucky with the instructions. has anyone any idea's how to "Pair" my mobile phone with it? The unit is now fully charged and ready to go if only I could pair it with my phone. If there is Anyone out there with a copy of the instructions I would be very Grateful. The model is the Supertooth II with the flip out speaker. Thankyou.
