6 Important safety instructions
Please read and strictly observe the following instructions!
You are not permitted to disassemble, modify or repair the car radio.
Never open the case of the car radio; it does not contain any serviceable parts! If the case is open, there is a risk of fatality
due to electric shock.
Do not give your car radio and especially the accessories to children. Never let your children use electrical devices without
supervision. Children are not always able to recognize potential hazards. Also keep the packaging films away from children.
There is a danger of suffocation.
The car radio and the accompanying components may not be exposed to dripping or sprayed water. Make sure that no
containers filled with liquid, such as bottles or cups, are placed in the vicinity of the device.
Make sure that the display is not exposed to any bumps. This can damage the display.
Please familiarize yourself with the different functions of your device before you begin driving. Excessively high volumes can
pose a risk for you and other people in traffic. Therefore always select the volume at such a level that environmental noises
(horns, sirens, etc.) can still be perceived.
Multimedia CDs also contain recordings of files other than audio files. If you play such a CD despite the warning information, it
may result in noises at a volume that endangers traffic. Furthermore, the power amplifier and speakers might get damaged.
Don’t use the car radio at an excessive volume. This poses a risk to your hearing.
Please only perform lengthy changes of the device settings while the vehicle is parked. Your concentration might be affected
by the changes.

Please observe the following safety instructions for the connection of the device:
Read the entire installation section before connecting the device.
Disconnect the negative pole of the vehicle battery for the duration of the installation.
Observe the safety instructions by the vehicle manufacturer during this task.
If you need to drill holes for the installation, make sure that no parts of the vehicle are damaged.
The cross section of the plus and minus cable may not be less than 2.5 mm².
Do not connect any plugs or cables from the vehicle to the radio without the appropriate expertise!
Only use the supplied cable to connect the device.
Depending on the build of your vehicle, the installation may deviate from this description.
We do not assume any liability for damages caused by faulty installations or connections, nor any subsequent damages.

Note:
We recommend that you have the device installed by a specialized company. Then you will have created the prerequisites for
a problem-free functioning of the device. If at any point during the installation you are unsure that you can correctly connect
the device by yourself, contact a specialist. A faulty installation may cause damages to the device and the vehicle electronics.
1. For the installation of the device, please remove the transport safety screws on the CD drive first.
2. Then remove the installation frame from the device with the aid of the disassembly key, by sliding the disassembly keys into
the provided openings on the right and left side of the device, as described in Illustr. 8.1. Make sure that the protrusion on
the disassembly key (Illustr. 8.2) points away from the device while it is being inserted. Afterwards, the frame can be slid
down over the device towards the rear.
3. Now slide the installation frame into the installation slot provided for the car radio.
4. Now attach the installation frame by bending the installation brackets towards the outside with a screwdriver. The frame is
properly installed when it can no longer be pulled out, yet also keeps from sliding into the installation slot.
5. Now connect the cable set and the antenna corresponding to the Illustr. 8.3 and Illustr. 8.4 as well as the table below to the
vehicle’s electric system. Also observe the specifications in sections 8.2 to 8.4.

Caution:
This device is distinguished by a high output level. This results in a
strong heat generation during the operation. Therefore no cables or
other components may be near the device. If their insulation melts,
there is the danger of a short circuit or fire.
8.2 Connecting the antenna
The device is designed for antennas with an impedance of 75Ω to 150Ω. To connect the antenna, plug the antenna cable into
the antenna socket of the device (black cable, socket on the rear of the device).

8.3 Supply voltage
ISO plug A:
A4: Attach the connection for +12V operational voltage (diameter at least 2.5 mm² for positive and ground wire) to terminal # 30
(permanent plus) of the vehicle.
A5: +12V switching voltage output (max. 0.5 A). When the device is turned on, the switching voltage adjoins contact A5 and
serves to retract or extract an automatic antenna and as operational voltage for antenna amplifiers.
A6: Connection for operating unit light.
A7: Connection for +12V trigger voltage. Connect to terminal # 15 of the vehicle.
A8: Connect the connection for the ground (diameter at least 2.5 mm² for positive and ground wire) to terminal # 31 (ground) of
the vehicle.
