most are 0000, what type of device are you trying pair? It maybe a compatability issue. you may need to call your OEM for the b/t device or your carrier for support
Have paired many devices to my 8310 and always use 0000 unless the documentation that came with said devices says otherwise. As previous posts state if you can't find it with the device documentation try the manufacturers website.
