Installation guide

6.5.2 Checking the installation

When the ISO connection cable is correctly installed, a call remains active until the call is ended, even if the ignition has already

been turned off beforehand. The system switches off automatically when the call has been ended. If the system switches to off

immediately switches off,then exchange the ignition lead (blue) with the power supply lead (red) as shown in Fig. 11b

PLEASE NOTE, the fuses should remain in place when opening the fuse compartment, make sure that they are not inadvertently

exchanged!

6.5.3 Additional external speakers

In the following cases, additional speakers (4 Ω, min. 5 W) must be used:

→ when the car audio system speakers should not be used

→ when the output rating of the speaker channel is greater than 35 W (Sinus) and the car audio

system has no phone connection option

→ when the car audio system is used with active speakers and has no phone connection option

Feedback interferes with the clarity of calls. Mount additional speakers at a distance of at least 31 in from the microphone. When

mounting additional speakers, please observe the manufacturer‘s installation instructions. Speakers can be connected to the

green (pin 14) and the purple (pin 7) leads of the connection cable. First of all, the purple and green leads must be disconnected

from the ISO connector (see Fig. 12).
