Microphone
Careful selection of the mounting location of the microphone can
increase the quality of voice transmission.
Mount the microphone approx. 30 cm from the driver's head, and
position it so that it points towards the driver's mouth. Experience has
shown that the best locations are near the rearview mirror or the sun
visor. We recommend that you keep the microphone a minimum
distance of 1 metre away from the Advanced Car Kit phone loudspeaker
to avoid feedback.
Take care to mount the microphone so that it is not exposed to air
streams from the vents. Do not lay the microphone cable in the heating,
ventilation or AC system. Use the double-sided adhesive tape supplied
to fix the microphone as this will prevent noise from the car body being
transmitted into the interior.
Insert the plug into the "MIC" socket in the handsfree unit and turn it
clockwise to lock it firmly.
Note: Use of any other microphone than the microphone
supplied with the Advanced Car Kit (HFM-8) may impact the
transmission quality.
Cable set
The wires making up the cable harness are to be connected as per the
wiring diagram.
• Connect the black wire to the vehicle ground (GND).
• Connect the yellow wire to the MUTE connection of the car radio.
If your car radio does not have a mute connection, this line may
remain unconnected. In this case, your car radio will not be muted
automatically during a call.
