Traffic safety As the driver of a motor vehicle, it is your responsibility to pay attention to the traffic situation at all times. Never use your car radio in a way that could distract you. Should the traffic situation become particularly demanding, we would advise you not to use the radio. Please keep in mind that you travel a distance of 14 m per second at a speed of only 50 km/h. When adjusting the volume, make sure that you are still able to hear sounds coming from outside of the vehicle, so that you are always able to react to warning signals.

Care of your audio equipment
We recommend that you use only C60/C90 cassette tapes in your car radio. Protect your cassettes from dirt, dust and temperatures exceeding 50 C. During cold weather, allow cold cassettes to warm up somewhat before playing them in order to avoid uneven tape transport. Operating problems and sound distortions may occur after approximately 100 hours of playing time and are caused by dust particles which adhere to the rubber roller pad and the tape head. Use a cleaner cassette to remove normal dirt build-up. If more dirt than usual has accumulated, use a cotton bud dipped in rubbing alcohol to clean these parts. Never use any hard tools.

Note: If there is too much tension on the cassette tape during playback, it may switch to the other track by itself. Check the condition of the tape. Sometimes it helps to rewind the cassette tape completely.
