Installation Mount the microphone about 30 cm (11.8 inches) from the driver's head, and position it so that it points toward the driver's mouth. Experience has shown that the best mounting locations are near the rear view mirror or the sun visor. Mount the microphone at least 1 meter (3 feet) away from the car kit loudspeaker to avoid audio feedback. Mount the microphone so that it is not exposed to air streams from the vents. Do not place the microphone cable in the heating, ventilation, or air-conditioning system. Use the supplied double-sided adhesive tape to fix the microphone to reduce the amount of background noise of the car that can interfere with your calls. Insert the microphone plug into the microphone connector on the hands-free unit, and turn the plug clockwise to lock it firmly. Use of any other microphone than the microphone MP-2 supplied with the car kit may impact the audio quality.
