INSTALLATION

INSTALLATION INSTRUCTIONS

- Insert the radio in the ISO slot for car radios in your vehicle, or select another location for installation where it will not affect the driver's ability to drive.

- Connect the cable shortly before finally installing the device and check the station memory function.

- If changes have to be made to the vehicle, consult a vehicle dealer or specialist workshop. Incorrect installation can lead to malfunctions affecting the complete electrical system of the vehicle.

- If necessary use vehicle-specific ISO adapters for installing the car radio. These adapters can be obtained from specialist workshops, dealers, or specialist departments of car equipment warehouses.

• Install the unit in such a manner that no injury can be caused during heavy braking or other driving situations.

- Note that the functioning of the car radio may be impaired if it is installed at an angle of more than 30% from a level position.

- Ensure that the car radio is not exposed to excessive temperatures (e.g. from direct sunlight or air from the in-car heating system), dust, dirt, or excessive vibration.

PREPARATION

- Before installation always remove the two transportation safety screws in the upper part radio casing (recognisable by their red flags)!

- Now remove the mounting frame from the casing of the car radio.

- Remove screws before installing.

PROBLEMS DUE TO INCORRECT CABLE CONNECTIONS

In some vehicle models, the standard arrangement of the cables [4] and [7] in the ISO block A (see below, "ARRANGEMENT OF THE ISO BLOCK") is exchanged at the factory.

If this is the case in your vehicle, certain functions may be impaired: stations may not be stored properly, for example.

To solve this, the red cable switched plus and the yellow cable (permanent plus) will need

to be reversed in the ISO block.

This service allows the station's name to be displayed.

• AF (Alternative Frequencies):

The car radio automatically searches for an alternative frequency for the current station with the strongest signal.

- TP/TA (Traffic Programme / Traffic Announcement):

Traffic information

• EON (Enhanced Other Network Information)

If there is a traffic announcement, then this enables the radio to switch to the radio station broadcasting it even if you are currently listening to another station.

SEL (1) Confirm
BND (6) Move between characters
Multi-purpose control (1) Scroll through all available letters and numbers

When producing your MP3 CDs please ensure that the tracks are listed either individually or in folders. Never mix tracks and folders as this can lead to problems during playback and especially when searching. All standard MP3 codings can be played by the unit.

MP3-PLAYER (CONT.)

ID3 TAG

This feature refers to a block of information stored on an MP3 CD lying "behind" the actual music information on the MP3. Among other things, it includes the name of the artist, the name of the track, the name of the album, the year it was released, the style of music, and in some cases notes.

The car radio can read this block of information and show it on the display (3). This is more user-friendly than with an audio CD, where only the title (track) numbers are displayed.

When producing your MP3 CDs, please take care to ensure that you can input or modify the ID3 tag for your MP3 CDs yourself using an ID3 tag editor available from specialist providers.
