Radio equipment — noise reduction (elimination of interference) (Opel Omega A)

1. The interference elimination equipment is installed serially at the manufacturing plant. If noise and interference occur, check the correctness of the connection and the quality of the ground loop on the body and antenna.

2. Radio equipment that is installed instead of the factory-installed one may be more sensitive to interference. In this case, it is necessary to use an additional filter.

3. If interference occurs when the windshield wiper motor is running, a filter must be installed in the motor power supply circuit. Make sure the filter has sufficient capacity.

4. The ignition system is already equipped with a noise suppression system.

5. If necessary, consult a specialist on how to eliminate interference.
