General 

The intercom can be operated at any time regardless of the position of the drive switch.

The interior microphone (B25/3) is located in the glove compartment.

The acoustic signals from outside of the vehicle are picked up by the two microphones in the right and left outside rearview mirrors (B25/4, B25/5) and can be heard on the interior loudspeaker (H10/1). Transmission is accomplished by the exterior loudspeaker (H10).

Voice connection from outside to inside 

By actuating the microphone switch (1) the exterior microphones (B25/4, B25/5) are activated. The radio switched on is simultaneously set to "mute".

In this operating position the external noises are audible, it is therefore possible to talk to the vehicle passengers.

The interior loudspeaker (H10/1) located in the right A-pillar paneling makes the sound audible in the passenger compartment.

An additional loudspeaker is integrated in the interior microphone (B25/3) so that it is possible to hold the interior microphone directly against your ear similar to a telephone when it is difficult to understand.

The communication distance to the vehicle is between 3 and 5 m depending on the ambient noise.

Voice communications from inside to outside 

Voice connection from inside to outside is always possible when the speaking key (1) is actuated regardless of the microphone switch (2).When the speaking key (1) is actuated the exterior microphones (B25/4, B25/5) are deactivated.

The acoustic signals are always preamplified in the interior microphone (B25/3).

The voice reproduction is accomplished via an external loudspeaker (H10) located in the left front area below the bumper.

The volume can be set with the control key (3).
