MODELS 203.0 /2 /7 with CODE (359) TELE AID emergency call system, lowcost 

Normally, the telephone connection is established via the telephone antenna (A2/22), which is on the roof of the vehicle. If there is a problem or fault with the telephone antenna (A2/22) (such as in the case of a vehicle rollover), there are two emergency antennas located in the rear bumper. These antennas are basically made up of the emergency call system antenna diplexer (A2/25), the emergency call system backup antenna on the left side (A2/54) and the emergency call system backup antenna on the right side (A2/55).

The emergency call system control unit (N123/4) detects the failure of the roof antenna and automatically actuates the emergency call system backup antenna on the left side (A2/54) and emergency call system backup antenna on the right side (A2/55) by means of a discrete line.
