Important Notes

What You Should Read By All Means!

Before starting to use your new car radio, you should carefully read through the safety notes and the information about the 'KeyCard'.

Safety Notes

Being the driver of a motor vehicle you should dedicate your full attention to the traffic around you. Therefore always use your car stereo such that you are able to cope with the present traffic situation in any moment.

In difficult driving situations you should turn your set off. Please take into account that at a speed of 50 km/h you are almost covering a distance of 14 m per second!

When adjusting the volume, always make sure that acoustic signals from the outside can still be heard in order to be able to react to alert signals just as it is required by the present situation.

If you would like to mount or expand the unit by yourself, you should by all means read through the enclosed mounting and connection instructions before.

Do not connect the loudspeaker outputs to ground!

Only use the accessory and replacement parts approved by Blaupunkt.

Due to the high output power of the output stage, the metal housing of the set may heat up considerably. Therefore never touch this metal enclosure when removing the unit.

KeyCard

Your car radio is theft-protected and cannot be operated without the KeyCard. Therefore, other people cannot make use of your set. Since it is not possible to utilize the car radio with another KeyCard, it will be of no worth at all for a thief - in case the KeyCard was removed before.

Wrong KeyCard

If a wrong KeyCard is inserted, four dashes are first represented on the display ('----') before the indication changes to 'CARD ERR'. During this period the set cannot be operated even with the right KeyCard.

- Remove the false card. Now the correct card has to be inserted by all means.

After the third false try it will take one hour before the set can be operated with the correct card. In the meantime, '----' is indicated on the display.

After another 16 wrong attempts, the car stereo can only be put in operation by one of our authorized service partners. For this, the car radio passport has to be presented.

Switching the car stereo off during the waiting period will set the waiting time to 'zero' after the unit has been activated again.

KeyCard Lost

If you have lost your KeyCard or if it was damaged, one of our authorized service partners will help you against presentation of your car radio passport.

These service partners are designated by an in the radio's service register. If required, call the service centre of your country for detailed information about your local Key-Card service facility.

If you want to cancel this function:

- Press the PS button ⑬ once again. The station currently sampled is maintained.

Traffic Messages (ARI)

(only FM)

Many FM stations broadcast the current traffic messages for their coverage area at regular intervals.

Together with the programme, the traffic stations transmit an 'ARI signal', which lets your car radio detect the actual traffic station and the zone identification. These individual zones are illuminated on the display ¹⁸ m (in Germany, for example, 'C' signifies that the station airs traffic messages for the North Rhine-Westphalia area).

The traffic stations indicate the beginning and the end of the message by an additional signal. Traffic messages are 'put through' with a preset volume, the level of which can be programmed (see chapter 'Programming'). The set automatically interrupts tape or CD playback and resumes play as soon as the message is over.

Switching Traffic Messages (ARI) On and Off

For switching ARI on and off

- Press the ARI button ⑯. If traffic radio is on, 'ARI' lights up on the display ⑱h.

When pressing the ARI button while listening to an MW or LW station, the unit automatically switches to an FM traffic station. When ARI is activated, you can only capture traffic stations which transmit an ARI signal.

Acoustic Alarm

When leaving the coverage area of the tuned in traffic station, your car radio automatically sends out an acoustic alarm after approximately 30 seconds.

This alarm tone can also be heard when pressing a preset button with no ARI station allocated to it.

For switching off the acoustic alarm,

- search for a new station (see chapter 'Tuning in a Station Automatically'). The set will then start searching for the next traffic station.
