OTHER DAB+ MENU OPERATIONS
Press and hold the INFO / MENU button to access the menu control. Then press the ◀ or ▶ button for different options as described below.
IMPORTANT INFORMATION REGARDING DAB+ RECEPTION
DAB+ radio reception is different from FM radio reception.
• In FM, you can often still receive a weak station, but probably with a rustling or crackling sound.
- DAB + reception works digitally and if there is not enough signal you hear nothing. No hiss or crackle as with FM. This is not due to the radio, but to the fact that there is not enough DAB+ signal at that location.
- DAB + rule is: no or weak reception = no sound.
What can you do if you do not have direct DAB+ reception.
• Always point the antenna straight up vertically first.
- Move the radio a few meters.
- Turn on the radio and activate a full scan in the DAB+ menu
- Do not place the radio too close to potential sources of interference such as, battery chargers, rotating machinery, computers, large metal surfaces, etc.
- In the display of the radio you will see the progress of the scan and the number of stations found in the current position of the radio.
Important
- With DAB+ reception, there can be a very big difference in reception level between one location and "a few meters away". In case of a local weak DAB+ signal, move the radio to find a stronger signal.
- If you take the radio to another location, perform a full scan again. This will show you which DAB+ stations can be received there.
Dynamic Range Control (DRC)
DRC can make quieter sounds easier to hear when the unit is used in a noisy environment. The DRC level of a broadcast is set by the selected radio station and transmitted with the service. Changing the DRC value on your unit enables you to apply a scaling factor to this level.

DRC OFF No compression
DRC HIGH Maximum compression as sent with the transmitted service
DRC LOW Set to 1/2 that of the sent transmitted service
