Setup option 1

For phone calls, use the ISO system cable CA-139 (if supplied with the
car kit), or a cable specific to the car radio, to connect the car kit to the
car radio and its speakers.

For music, use a cable specific to your car radio to connect the 3.5-mm
(0.14 inch) stereo output to the AUX input of the car radio.

You can connect the car kit to a loudspeaker with an impedance of at
least 2 ohms. The optimal impedance for the car kit is 4 ohms. If the
impedance is over 8 ohms, the output power is significantly lower than
normal.

1. Disconnect the two ISO connectors from the car radio for power and

loudspeakers, and replace them with the two connectors of the
system cable CA-139.

pinning of the car radio. Leave the other labeled mute wires

connected as they are. Connect the wires of the same colour
together.

For phone calls, connect the system cable CA-139 to the power
output and the loudspeaker output of the hands-free unit.

2. Check the +12-V power pin and the ignition pin of the two ISO

connectors coming from the car and the respective pins of the
system cable CA-139. If necessary, swap the two wires of the system
cable. Connect the system cable to the two open ISO connectors.

3. Connect the stereo music output of the hands-free unit (a standard

3.5-mm stereo connector) to the AUX input of the car radio. Use an
appropriate cable specific to your car radio (this cable is not supplied
with the car kit).

4. To charge a compatible Nokia mobile device through the car kit,

connect one end of the connectivity cable CA-113CU to the hands-
free unit and the other end to the 2.0-mm (0.08 inch) charging
connector of the mobile device.

To play music from a mobile music player that has a standard 3.5-
mm (0.14 inch) audio connector, plug the 3.5-mm (0.14 inch)
connector of the connectivity cable to the music device.

After you have made all the connections described above, connect the
external input device CU-10 and the microphone MP-2 to the respective
connectors on the hands-free unit.
