Operating instructions

Installation of the hands-free car kit
In the operating manual of the radio device, you can find the pin assignment for the “mute” signal. This
signal can occur on one of three cables marked with “mute1”, “mute2”, or “mute3”.
Connect the yellow “mute” cable to the switch box using the correct cable from the car radio: “mute
1”, “mute 2” or “mute3”.
Attention:
The positive wires and ignition wires are protected in the casing of the switch box with X
3A fuses. For this reason a separate fuse, as shown in the next chapter, is not necessary.
