Scan DAB stations
Digital Audio Broadcasting (DAB) is a digital broadcasting standard for terrestrial reception of digital radio. A list of radio stations which can be received in Germany is available on the Internet at www.digitalradio.de.
i NOTE:
In Germany approx. 70% of the country's area is covered by digital radio broadcasts (as of Nov. 2011). In the individual areas however, coverage and provision vary greatly. If the DAB stations in your region cannot be received or only with interferences depending on location, in this case you can switch to the FM band to receive this station. This is only possible however if these stations are broadcast via UKW. Find out more on the internet site of the radio station.
- Press the FM/DAB button (24) repeatedly until "DAB" appears on the display.
- You can select the next or the previous station by using the / < buttons (6).
- If the reception is too weak and the received station "motorboats", try to improve the reception by changing the position of the antenna.
i NOTE:
- For an optimal DAB reception, we recommend that the dipole antenna be aligned vertically.
- You cannot toggle between Mono and Stereo during DAB reception.
- To manually set a DAB frequency, proceed as described in the "Settings menu" section.
Display additional DAB information
In DAB mode, you can display the following additional information if broadcast by the radio station. To do so, press the INFO button (21).
The DLS text is shown on the display by default.
- DLS: Short for Dynamic Label Segment. This involves complementary data. This content may be e.g. information about the station or the music title and artist being played.

Settings menu
Numerous settings are made via the Settings menu (see page 4).
In the Settings menu you can find the main menu and the related submenus with the individual options.
To call up the menu, press the MENU (20) button during operation.
- Use the > 按钮 (6) to navigate in the menu.
- Use the ENTER button (19) to select a submenu, or confirm a setting.
- To leave the menu, press the MENU button once more.
NOTE:
- If you do not press any button within 10 seconds, the menu is hidden.
The currently set option is highlighted by
A Settings menu can be found in DAB mode, as well as in FM mode. The DAB and FM menu is explained below along with the general SYSTEM menu.
DAB Menu
The DAB menu is divided into menus: Autoscan, Manual tune, DRC and Prune.
Autoscan: Starts the station scan. The DAB frequency band is scanned for stations.
- Manual tune: To do so you need to know the station frequency. This can be found on the internet site of the broadcasting service. Select individual frequencies using the >/<buttons (6).
- DRC: short for Digital Range Control (dynamic range). The term DRC describes the ratio between the quietest and the loudest sound. If the dynamic range is very high there are very soft sounds as well as very loud sounds. Under some circumstances this may present a problem
with playback. Let us assume that you are listening to a radio station in a relatively loud environment. By increasing the volume you can play the quiet sections louder. This however has the disadvantage that the loud sections become uncomfortably loud. It makes sense here to reduce the dynamic range. Select between the options:
- DRC off: The dynamic range is not reduced.
- DRC high: The dynamic range is sharply reduced.
-
DRC low: The dynamic range is slightly reduced.
-
Prune: It may be that you can no longer receive some stations after a station scan or change of location. With this function you can delete these stations from the reception list. Select "YES" and confirm with the ENTER button.
FM Menu
-
Scan setting: Select the desired option in order to perform an automatic station scan.
-
Strong stations only: Only search for strong radio stations.
- All stations: Search for all receivable radio stations. In doing so, the scan also pauses on weak stations.
DAB + FM Menu (SYSTEM)
The following submenus can be found in the SYSTEM menu.
Factory reset: Select the "YES" command if you want to reset the device again to the factory defaults. All settings which you have made will be lost.
- SW version: Here, you can display the Software Version of the device.
AUDIO IN jacks (rear of the device)
For the connection of analog playback devices via this socket, you may also hear the sound from other playback devices such as MP3 players, CD players, etc., through the loud-speakers.
- Connect the external device to the AUDIO IN jacks on the rear of the device with a cinch cable (2x RCA). If required, use a suitable adapter (not included).

NOTE:
If possible, adjust the volume of the external unit to a comfortable level.
To play back music via Bluetooth
Bluetooth involves a technology for wireless radio connection of devices over a short distance. Devices with Bluetooth standard are transmitting between 2.402 and 2.480GHz in the ISM band (Industrial, Scientific and Medical). Interference can be caused for example by WLAN-networks, DAB radios, cordless phones, or microwave ovens which work on the same frequency band.
This device offers you the possibility to use a Bluetooth-enabled device. The functional radius is limited to approx. 15 metres depending on the surroundings and the unit used. If your playing device supports the A2DP profile (Advanced Audio Distribution Profile) and has a music-player function, then you can also wirelessly transfer music to the device. The A2DP profile involves a multi-vendor Bluetooth profile. By streaming, stereo-audio signals are wirelessly transferred between the playing device (source) and the receiving device. To be able to control the source remotely, the playback device must support the AVRCP profile (Audio Video Remote Control Profile).
Due to the different device manufacturers, models, and software versions, a full functionality cannot be guaranteed.
Logging on devices (Pairing)
Before you listen to music via the unit, you must pair the devices.
- Ensure, that the Bluetooth function is activated in your player (e.g. mobile phone). For this, refer to the operation manual of your player.
- Press the BT button (23). The control lamp (11) will blink rapidly.
- Chose the Bluetooth menu in your player and register the device in your player. For this, refer to the operation manual of your player. The device "AEG MC 4457" will show in your player as a selection.
NOTE:
Only one playback device may be connected with the music center at one time. If the music center is already connected with a different playback device, the music center will not appear in the BT selection menu. Press the CONNECT button (7) to separate the already connected devices. Now you may connect the music center with another playback device as described above.
- Now enter the password "0000" in your player, depending on the device manufacturers, model, and software version.
If the application was executed successfully, the control lamp (11) will light.
For the further procedure, please refer to the user manual of the playback unit. If possible, adjust the volume of the external unit to a comfortable level.
