Radio operation  
If you hold the button pressed, then the  
frequencies will move up or down more  
quickly.  
Traffic safety  
Select the frequency range  
As the driver of a motor vehicle, it is your  
responsibility to pay attention to the traffic  
situationatalltimes.Neveruseyourcarradio  
in a way that could distract you. Should the  
traffic situation become particularly deman-  
ding, 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 war-  
ning signals.  
You can choose between the frequency ran-  
ges:  
FM 87.5 – 108 MHz,  
AM 531 – 1602 kHz and  
LW 153 – 279 kHz.  
Adjusting station search sensiti-  
vity  
You can adjust the sensitivity of the automa-  
tic station search.  
Switch on the desired frequency range  
by pressing either the button FM • T or

Press lo • m.  
When “Io” is visible in the display, then  
only those stations with relatively strong  
signals will be picked up (low sensitivi-  
ty).  
When “Io” is not visible in the display,  
then stations with weaker signals will  
also be picked up (high sensitivity).  
Switching between AM and LW:  
Press M • L.

Technical data  
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.
