ENGLISH
You can select if the car kit amplifier is used for calls and the car radio amplifier
is used for music, or if the car kit amplifier is used for both.
If you want to use the loudspeaker SP-3 for calls, use the power cable PCU-4
instead of the ISO cable. For instructions, see the user and installation guide on
the CD.
You can connect the car kit to a loudspeaker with an impedance of at least
2 ohms. The optimal impedance is 4 ohms.
Use the car kit amplifier for calls and music
Make the connections as shown in Figure 1 to use the built-in amplifier of the car
kit for calls and music played on a device that supports the A2DP Bluetooth profile.
After you have connected the ISO cable, connect the input device CU-11 and
the microphone MP-2 to the hands-free unit.
Use the car kit amplifier for calls and the car radio amplifier
for music
Make the connections as shown in Figure 2 to use the amplifier and equaliser
of your car radio for music played on a device that supports the A2DP
Bluetooth profile. The built-in amplifier of the car kit is used for calls.
Cut the loop indicated with scissors in the figure.
Connect the stereo outputs of the hands-free unit 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).
