stance of 14 m per second at a speed of only  
50 km/h.

Security code  
Keep your car radio passport with the code  
number in a safe place in order to avoid  
“unauthorised access” to your car radio.  
When the security code system is activated,  
the unique code must be entered each time  
the power to the unit was interrupted.  
The radio will function again as soon as you  
have entered the correct code.  
If you have lost your radio passport and  
forgotten the code number, your radio can  
only be made operable again by one of our  
authorised service workshops, which is sub-  
ject to payment.  
This car radio is supplied with inactive code  
protection. In order to switch the security  
coding system on, proceed as described in  
the following.  
If the coding system is active while the power  
supply to the system is interrupted (e.g. theft,  
disconnection of the car battery), the set will  
be electronically blocked. In such a case it  
canonlybemadeoperableagainbyentering  
the correct code number given in the car  
radio passport.  
To confirm the code number:  
Press the  
button.  
Now the security coding system is active.  
ThedisplaywillbrieflyshowCeachtimethe  
set is turned on.  
If the display shows “CODE ERR”, you have  
entered a wrong code. Re-enter the correct  
code after the waiting time (“CODE” will ap-  
pear in the display).  
If you switch off the set while it is blocked, the  
waiting time will start anew as soon as the  
radio is turned on again.  
Entry of a wrong code number  
It should not be possible for a thief to find out  
the correct code number by trial and error.  
Thisiswhythesetwillbeblockedforacertain

been entered. The display will then show  
“- - - -”.  
After the first three unsuccessful attempts  
the system will lock for 10 seconds; after  
further attempts, the waiting time extends to  
one hour.  
Switching on security coding  
To activate the coding system:  
Turn off the radio.

After 19 unsuccessful attempts the display  
will show “OFF”. In this case you can no  
longer re-start the unit.

strong, local stations (low sensitivity).  
If “lo” does not light up, the radio will also pick  
up weaker, distant stations (high sensitivity).  
Make sure that “m” is not indicated in the  
display.  
Prerequisite: “AF” and “m” do not light up in  
the display, i.e. the Alternative Frequency  
function and manual tuning are switched off.

Receiving traffic programme stations with RDS-EON  
Many FM broadcasters offer traffic messa- To switch the priority on or off:  
Automatically storing the stron-

ges for their service area at regular intervals.  
All traffic programme stations transmit a spe-  
cial carrier signal alongside their program-  
mes, which is decoded by your car radio. If  
this signal is identified, “TP” will appear in the  
display (Traffic Programme).  
Press the TA button.  
When pressing TA while a message is being  
broadcast, this message will be interrupted.  
The unit will then switch back to the previous  
condition. The priority for other traffic messa-  
ges remains active.  
You can automatically store the five most  
powerful FM stations of your current recepti-  
on area sorted according to their signal  
strength.  
This function is particularly convenient on  
longer trips.  
In addition to these, there are also stations  
which do not actually transmit traffic pro-  
grammes themselves, but by using RDS-  
EON they offer the possibility to receive the  
traffic messages broadcast by another traffic  
programme station in the same radio net-  
work. If you listen to one of these stations  
(e.g. NDR3), “TP” will appear in the display  
as soon as the priority for traffic programme  
stationshasbeenactivated, i.e. “TAmustbe  
displayed.  
Warning beep  
Press the TS button briefly.  
The radio will search for the strongest FM  
stations and store them on the memory bank  
“T” (Travelstore). When this process has  
been completed, the radio will play the first  
station.  
If desired, stations can also be stored manu-  
ally on the Travelstore bank (see “Storing  
stations”).  
If you leave the reception area of the traffic  
programme station currently tuned into, you  
will hear a warning beep after approximately  
30 seconds.  
This alarm tone will also be released when  
pressing a preset button which has no traffic  
programme allocated to it.  
If a traffic announcement is broadcast, the  
radio will automatically switch to the linked  
traffic programme station (in this case,  
NDR2) for the duration of the message and  
return to the original programme (NDR3)  
afterwards.
