Safety Information

Read the operating instructions carefully before putting the appliance into operation and keep the instructions including the warranty, the receipt and, if possible, the box with the internal packing.

• Use the device only for the intended purpose.
- The device should be installed in such a way that existing ventilation holes are not covered.
- Never open the housing of the device. Incorrect repairs can constitute a considerable risk for the user. If the device is damaged it should not be used, but repaired by a specialist.

These symbols may be found on the machine and are intended to indicate the following:

The symbol with an exclamation mark should advise the user of important operation or maintenance instructions in the accompanying documentation.

Devices bearing this symbol work with a "class 1 laser" for tracing the CD. The built-in safety switches should prevent the user being exposed to dangerous laser light, which is invisible to the human eye, when the CD compartment is opened.

Under no circumstances should these safety switches be bypassed or manipulated, as this could result in a danger of exposure to the laser light.

Symbols in these Instructions for Use

Important information for your safety is specially marked. It is essential to comply with these instructions in order to avoid accidents and prevent damage to the machine:

WARNING:

This warns you of dangers to your health and indicates possible injury risks.

CAUTION:

This refers to possible hazards to the machine or other objects.

NOTE:

This highlights tips and information.

English

Children and Frail Individuals

- In order to ensure your children's safety, please keep all packaging (plastic bags, boxes, polystyrene etc.) out of their reach.

WARNING!

Caution! Do not allow small children to play with the foil as there is a danger of suffocation!

Road Safety

WARNING:

• Road safety is of paramount importance. You should therefore use your car radio at all times in such a way that you are able to cope with the current traffic situation.
• Please remember that at a speed of 30 mph (50 kph) you travel 15 yards (14 metres) in one second.
  • We advise you not to operate the radio in critical situations.
• It must be possible to hear the sirens of police and fire brigade vehicles etc. from inside the vehicle in good time.
• When driving you should therefore not turn the radio volume up excessively.
• In order to avoid serious road accidents, the device should be installed in such a way that you are not hindered when operating the steering wheel, gear lever etc.
  • Similarly, safety aspects such as airbags and your clear view of the road must not be obstructed either.

Safety notes for the time of assembly/connection

• First disconnect the minus pole and then the plus pole of the battery. (connection in the reverse order.)
  Please note: Once the battery has been disconnected the information is lost from all volatile memory. Please note the safety information provided by the vehicle manufacturer.
• The main fuse must be installed as closely as possible (not more than 30 cm away) to the plus pole of the battery so that the car is protected from any cable fire caused, for example, by an accident. If the above is not complied with the insurance protection no longer applies.
• The cross-section of the plus and minus cable must not exceed 1.5 mm ^2 .

38 English

Installation Tips

• Cable protection sleeves protect cables against fraying on sharp body parts.
• The insulation of the cables must not be damaged during installation.
• It is essential to use the correct tools when installing car hi-fi.

Depending on the model, your vehicle may deviate from the above description. We do not accept any liability for damage caused by installation or connection errors or for consequential damage.

Important Information for installing your carradio!

1. The device is designed for the minus pole of the battery, which must be connected to the body of the vehicle. Please check this before installation.
2. When installing/connecting your device please note that not every vehicle is equipped with an "ISO connection". In this case we recommend the use of an ISO adapter specifically designed for your vehicle.

Adapters are available from car accessory shops and/or from your vehicle workshop.

1. Depending on the specific car type, different wiring connection of the "Duration +" wire (Constant current connection) are available. (However, this is necessary for storing the radio stations).

In order to guarantee all functions, installation in line with these instructions is essential. In cases of doubt please contact an authorised car workshop.

Due to the various types of motor vehicles and motor manufacturers, it is not possible to guarantee that the pin assignment of the ISO plug is correct, even if the ISO plug connections fit together mechanically. It may therefore be necessary to modify the electrical connection or use vehicle-specific adapters.

i NOTE:

If the device is correctly connected, the radio can be switched on and off via the ignition. If the stored stations are lost, this indicates that the radio is not receiving any "continuous +", current which is required for storing the stations.

CAUTION:

Where there is a connection to "continuous +" without the ignition being switched on, the car battery might be drained of power even if the radio is switched off. This may even result in the battery becoming completely flat.

1. Depending on the specific car type, interferences may arise during radio/CD operation. These interferences can avoid easily with an additional Interferences filter. Your car radio is originally prepared with an Interference Filter already.

In these case, please contact your authorized car dealer.

1. When installing your radio please ensure that there is enough space at the rear of the radio to ensure sufficient cooling.

2. For the antenna connection there are two different norms. The first of these is the old (50 ohm) version with a long protruding round contact on the vehicle and a round socket on the radio end. The second is the ISO-standardised antenna plug (150 ohm). Adapters for both formats are available from accessory manufacturers and/or your car workshop.

i NOTE:

Important information for VW/Audi vehicles: Your car may have an active antenna. It requires a power supply as it is provided only by original car radios. In this case, use a phantom-powered antenna adapter. Antenna adapters are available at car accessory suppliers and/or your automotive workshop.
