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.
