Installation
6. 1. Identify prerequisites
Vehicle
The system may be installed only in vehicles with an in-vehicle voltage of 12 V,
minus pole to ground. If no car radio is existing, an external loudspeaker is neces-
sary.
Telephone
In order to enable operation of this system, a Bluetooth
®
compatible telephone
must be used.
Muting
(radio mute switching)
The muting function ensures that the radio sound volume is switched off during
a telephone call. The muting is supported by the system. You can find out in the
documentation on the car radio whether your car radio has a muting connection.
The mute signal is a ground signal!
External loudspeaker / phone connection of the car radio
The switchover of the radio loudspeakers to the system is implemented through
switching contacts. These are designed for a maximum loudspeaker power of 35
W (sine). Loudspeaker powers above 35 W lead to premature wear of the swit-
ching contacts. Use either the telephone input of the car radio, or an external
loudspeaker at higher output power (5 W / 4
Ω)
.
Checking cable lengths
Before you attach the components permanently, check whether the mounting
locations are selected so that the cable lengths are sufficient in order to connect
the individual parts with each other. Consider the following references in the sti-
pulation of the installation locations.
Incorrect installation
Incorrect installation can lead to damage to the device or the
vehicle! Special knowledge and capabilities are necessary for the
installation of the handsfree system. Incorrectly connected cables or
short-circuits can lead to serious device damage. Before you begin
with the installation, the car battery needs to be disconnected.
It is urgently recommended to have the installation carried out in a
specialist workshop.
