Anti-theft coding  
Installation/connection  
The car radio comes standard with the code  
system deactivated.  
What you need to know!  
The code system can only be switched on  
and off, if the radio is connected to perma-  
nent power.  
If you like to install your new car radio by  
yourself or add other audio components to  
the existing ones, then please read carefully  
Before starting to use your new car radio you  
shouldcarefullyreadthroughtheinformation  
on “Traffic safety” and “Anti-theft coding”.  
If the anti-theft coding system is on while the  
power supply to the unit is interrupted (e.g.  
theft,disconnectingthecarbattery),thesetis  
electronically blocked. Then it may only be  
used again after the appropriate code num-  
ber has been entered (see car radio pass-  
port).

It should not be possible for thieves to ascer-  
tain the code number by trial-and-error. This  
is why the set will be blocked for a certain  
period of time, if an incorrect code number is  
entered. In this case, “- - -” will appear in the

an “ARI signal” during their programmes, so  
that your car radio can recognize them.  
Another signal is broadcast to indicate the  
beginning and end of a traffic message.  
Traffic messages are broadcast at a preset  
volume, the level of which can be regulated  
(see “Adjusting the volume for traffic messa-  
ges and warning beep”). If you are playing a  
cassette, it will be interrupted until the traffic  
message has ended and will then resume

Care of your audio equipment  
Technical data  
(Switching tracks during playback)  
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.

Output power:  
Press FR and FF at the same time.

At the end of the tape, the unit will automati-  
cally switch to the other track.  
During cold weather, allow cold cassettes to  
warm up somewhat before playing them in  
order to avoid uneven tape transport. Opera-  
ting problems and sound distortions may  
occur after approximately 100 hours of play-  
ing time and are caused by dust particles  
which adhere to the rubber roller and the  
audio head.  
Use a cleaner cassette to remove normal dirt  
build-up. If more dirt than usual has accumu-  
lated, use a cotton bud dipped in rubbing  
alcohol to clean these parts. Never use any  
hard tools.  
Note:
