Voice connection to vehicle, function

After the service center (police, fire brigade, German Red Cross, ...) has received a TELE AID emergency call telegram a radio connection is completed to the vehicle to interview passengers or persons involved. This allows rescue measures to be started depending on the actual severity of the accident.

The radio communiction between the vehicle and the responsible service center is accomplished via the telephone antenna and the CTEL transmitter and receiver (A35). If the telephone antenna does not operate due to an accident it is automatically switched over to the TELE AID substitute antenna (A2/50).

The telephone antenna depends on the model

Model 129: Rod antenna (A28)

Models 202, 208.3, 210, 220: Telephone antenna (A2/49a1)

Model 215: Telephone antenna (A2/22)

In general the voice connection is accomplished with the hands-free system of the telephone. The hands-free system consists of the hands-free system microphone (B25), the hands-free system loudspeaker (H4/12) and the CTEL transmitter and receiver (A35).

Depending on the vehicle model it is possible, however, to combine the hands-free system loudspeaker with other output systems, e.g. as double-coil loudspeaker (radio/telephone) in model 202 (H4/13) or as system loudspeakers in model 220 (H4/9, H4/10).

When the voice connection is completed TELE AID is also terminated.

Peculiarities in the case of a taxi emergency call (code 930):

The voice connection is normally limited to monitoring the passenger compartment via the hands-free system microphone (B25), since otherwise the person threatening would be warned or could be caused to panik. The service center only attempts to obtain further information in special cases.
