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.
Thedisplaywillbrieflyshow“C”eachtimethe
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

After the first three unsuccessful attempts
the system will lock for 10 seconds; after
further attempts, the waiting time extends to
one hour.

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

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. “TA”mustbe
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.
