I used this Motorola Bluetooth manual to connect my Motorola N136/HS 850 to my LG PM 325 phone. In the attached manual: Go to "using your headset" - "linking your headset and phone" and follow the instructions. You may need to revise the steps slightly to fit the functions of your phone. I followed steps 1 and 2, skipped step 3 and instead found the bluetooth icon on my phone, selected "add new", then selected "searching and pairing" and allowed the phone to search for and pair my bluetooth device. The Motorola Bluetooth device appeared on the screen of my phone within seconds as "Motorola HS850". I selected the device on the screen of my phone and followed step 5 entering the pin code "0000" and selected "connect" on my phone to begin using my bluetooth. I hope this helps someone.

I have an N136 which turns out to be an HS850 (with folding boom}. This model requires the boom to be folded while the answer button is held down, When the light comes on the boom must be extended before the light goes out. The light will now stay on and the phone should find your headset.
