Many FM stations broadcast traffic news for  
their reception area at regular intervals. Sta-  
tionsusingtheARIsystembroadcastanARI  
signalduringtheirprogrammes, sothatyour  
car radio can recognize them. Another signal  
is broadcast to indicate the beginning and  
end of a traffic message. These traffic mes-  
sages are broadcast at a preset volume. If  
you are playing a cassette, it will be interrup-  
ted until the traffic message has ended and  
will then resume operation.  
For each memory bank (I, II, III, T) you can  
store up to five stations using the button 1-5. (Travelstore)

Appendix  
Care of your audio equipment  
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.
