Important information
Traffic safety
As the driver of a motor vehicle, it is your
responsibility to pay attention to the traffic
situation at all times. Never use your car radio
in a way that could distract you. Should the
traffic situation become particularly deman-
ding, we would advise you not to use the
radio. Please keep in mind that you travel a
distance of 14 m per second at a speed of
only 50 km/h. When adjusting the volume,
make sure that you are still able to hear
sounds coming from outside of the vehicle,
so that you are always able to react to war-
ning signals.
Installation / Hook-up
If you would like to install your new car radio
yourself or add other audio components to
the existing ones, then please read the enclo-
sed instructions on installation and hook-up
carefully.
Do not ground the loudspeaker outputs!
Use only Blaupunkt-certified accessories and
spare parts.
