Microphone MP-2
Select the mounting location of the microphone carefully to increase 
the quality of voice transmission.
The best place to mount the microphone is close to the rear view mirror. 
Mount the microphone so that it points toward the driver’s mouth and 
at least 1 metre (3 feet) from the car kit loudspeaker to avoid audio 
feedback.
Ensure that the microphone cable reaches to the hands-free unit for 
connection.
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 supplied microphone may impact the audio 
quality.
ISO cable CA-135
If the ISO cable CA-135 is supplied with the car kit, you can use it to 
easily connect the car kit to a car radio that has ISO connectors. See 
“Integration with a car radio system”, p. 32.
