Instructions to additional installation of a radio receiver

The prevention

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

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

Co-ordinate a radio receiver with the aerial. For this purpose adjust low-power средневолновой the transmitter approximately on 1400 кГц. If there is no transmitter it is possible to apply the noise generator to adjustment. Turn a small screw-driver the screw of the 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.

The prevention

Thus turn the screw of adjustment a maximum only on 1/2 turns.
