Important information

Radio operation

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.

Select the frequency range

You can choose between the frequency ran- ges:

FM 87.5 – 108 MHz, AM 531 – 1602 kHz and LW 153 – 279 kHz.

Switch on the desired frequency range by pressing either the button FM • T or M • L.

Switching between AM and LW:

Press M • L.

Station search

m should not be lit up in the display. If it is, switch it off by pressing lo • m

press right or left.

The car radio will automatically tune into the next station.

If you hold the button pressed, the search function will forward quickly.

Manual station search

m (manual) must be lit up in the display. If it is not, switch it on by pressing lo • m.

press right or left quickly.

The frequency will move up or down in short intervals.

If you hold the button pressed, then the frequencies will move up or down more quickly.

Adjusting station search sensiti- vity

You can adjust the sensitivity of the automa- tic station search.

Press lo • m.

When “Io” is visible in the display, then only those stations with relatively strong signals will be picked up (low sensitivi- ty).

When “Io” is not visible in the display, then stations with weaker signals will also be picked up (high sensitivity).

Stereo - mono switch

If you would like to switch between stereo and mono reception:

Press lo • m for approximately 2 se- conds.

During stereo reception the stereo sym- bol will light up in the display.

Each time the car radio is switched on, the reception will automatically be set to stereo. The radio will automatically switch to mono when the reception conditions are poor.
