1). On the back of the MHF-R220BT unit you will see two pairs of clips. Place the bottom pair of clips on the underside of your existing rearview mirror. Lift the unit so that the bottom clips extend allowing the top clips to be fixed in position on top of your Rearview mirror and securely hold the handsfree unit in place. Adjust the fitted unit to your preference for clear rear vision.
2). Select a suitable position for the microphone depending on your vehicle type, this should be placed close to the users head - the driver sun visor is normally adequate.
"It is highly recommended to have the front of the microphone (side with more holes) directly facing the operator for the best voice pickup." The microphone can be placed either back or front of the visor by detaching, rotating and re-attaching microphone holder to correct side of the microphone.
3). Clip a microphone on the driver's sun visor recommended to keep a distance of the microphone from the MHF-R220BT unit as long as possible.
4). Insert the power jack of the power adapter cable (4M).
5). Connect the Power Adapter Cable into its respective socket on the MHF-R220BT unit.
6).The power lead should be secured and hidden into the vehicles interior using the seals or joins around the windscreen and door "A-Frame" and under your dashboard. Ensure that you leave yourself enough cable to be able to connect to your cigarette lighter socket.
Note : Please ensure that the microphone and power cable do not interfere with the safe operation of your vehicle.
