The microphone on my motorola hs850 won't work

How to place a Motorola HS 850 bluetooth headset into paring mode:

1. Close the boom to turn the unit off.
2. Hold down the call button until the blue light comes on.
3. While holding down the call button, swing the boom open.
4. (Now you can let go of the call button.)

The headset is now in pairing mode, and you can search for it using your phone. When it asks for a PIN, use 0000.

I bought one here - I'll let you know if it works

Whats most likely wrong with your HS850 is the connect button on the front of the headset (the larger oval chrome one with an inlay of a traditional phone handset on it)is stuck down. To repair this you will hold the hand set and pull up on lanyard attach point firmly. (This facia is held on by double sided tape). After pulling the facia you need to purchase or borrow a T-6 Torx bit to remove the screw that holds the headset together. Once you get to the circuit board you will see what the button and spring assembly are (all is is a round piece of foil and the "spring" is a piece of tape using tension to pull the foil up!) Reset the piece of tape so it does not rest on the board and reassemble that headset. Enjoy your HS-850
