Both serially established, and receivers acquired in trade have code number. It protects the receiver from unauthorized use. After inclusion of a radio receiver it is necessary to enter code number according to the maintenance instruction, otherwise it cannot be included. If the radio receiver is coded, define a radio code before a detachment of wires from plugs of the storage battery or its removal. If the code is unknown, place the automobile receiver in operation the manufacturer can only. Individual code number is specified in the radio receiver passport. This passport should not be stored in the car.

1. Disconnect from the plug of the storage battery a weight wire (–).

The anticreeping code of radio is thus erased.

2. Push two dismantling keys (51) and Take a radio receiver (A2).
3. Wring out lock springs (shooter) and extend dismantling keys.
4. On the back party of a radio receiver mark wires a sticky tape and remove them.


1. In the serial car the antenna cable, and also the line to the aerial with remote control of its promotion is not established, they are necessary for carrying out in addition.
2. Connect behind a wire radio receiver according to marking and according to the instruction of the manufacturer.
3. Insert with pressing a radio receiver into a console opening.
4. Connect to the plug of the storage battery a weight wire (–). Establish time on hours and program an anticreeping code for radio.

Instructions to additional installation of a radio receiver


If the serial connecting wire is not applied, surely pay attention to that there were no loose not isolated wires. Otherwise short circuit will lead to a wire peregoraniye. In shops it is possible to get adapters for radio receiver connection.

Pay attention to that the passed standard tests sets of elements (throttles, condensers) were applied to suppression of hindrances (with the general permission to operation of a vehicle of ABE only). In trade specially for Mercedes cars there are coordinated sets of elements for suppression of hindrances together with an erection manual.

Coordinate a radio receiver with the aerial. For this purpose adjust low-power srednevolnovy the transmitter approximately on 1400 kHz. If there is no transmitter, it is possible to apply the noise generator to control. Turn a small screw-driver the screw of coordination of the aerial (ahead at the left in the radio receiver case) until the best reception or a maximum level of noise will be reached.


Thus turn the control screw at most only on 1/2 turns.
