3.5 Additional functions
Telephone muting
The TechniSat WERRA 1 is equipped with a muting function which can be used in connection with a car telephone. When a call is received the radio changes to the muting mode. The message “PHONE“ is shown on the display. When the call is over the radio switches to normal reproduction.
In order to make use of this function it is necessary to connect the respective output of your telephone to the MUTE input of the radio via a suitable adapter (see chapter 4).
Motor antenna/amplifier antenna
The device is equipped with a switching voltage output to drive a motor antenna or to supply an antenna amplifier. When the radio is switched on a voltage of 12 Volt is lying on this output. When connecting the antenna (see chapter 4) follow its connection notes.
Supplementary audio amplifier (booster)
Via the cinch socket on the rear of the device you can tap the audio signals of the individual channels and transmit them to the supplementary amplifier (see chapter 4). If the amplifier used is equipped with a remote control input for switching on and switching off you can possibly use the switching voltage output of the motor antenna which is described above (follow to the connection notes).
4 Connection
4 Connection
The TechniSat WERRA 1 is equipped with connection sockets according to the ISO standard. In most of the cars with radio preparation the corresponding connectors are used. These are plugged into the radio together with the antenna connector, and your TechniSat WERRA 1 can be operated. When connecting take care that the power supply for the car radio is covered with at least 10 A. Please also note that it is only possible to connect loudspeakers with an impedance of at least 4 Ohm.
If your car is not equipped with the respective connectors you can connect the radio as shown in the following sketch, using the enclosed attaching plugs or special car adapters which can be obtained in specialist shops.
Do not install the device in a place where it is exposed to direct sunbeams or to direct stream of air from the heating.
