Radio operation with RDS (Radio Data System)
The Radio Data System offers you more convenience when listening to FM radio sta- tions.
More and more radio stations have begun to broadcast RDS information alongside their programmes.
As soon as a programme has been identified, the station name including a regional identi- fier, if applicable, will appear in the display, for example, NDR1 NDS (regional program- me in Lower Saxony, Germany).
When RDS is activated, the station buttons become programme buttons. You now know exactly which programme you have tuned into, making it easy to find the desired station quickly.
But RDS offers you further advantages:
AF - Alternative frequency
The AF (Alternative Frequency) function makes sure that the strongest frequency of the currently selected programme is always tuned in automatically.
This function is activated when “AF” appears in the display.
In order to switch this function on or off,
•press the AF button briefly.
The radio will switch to mute briefly while searching for the strongest reception signal. If “SEARCH” appears in the display when
switching on the radio or recalling one of the stored frequencies, the unit is automatically searching for an alternative frequency.
“SEARCH” will disappear from the display when the alternative frequency has been found or after the frequency band has been run through completely.
If the reception quality of the selected pro- gramme becomes too poor:
•Tune into another station.
REG - regional programme
Certain radio programmes are split up at times into regional programmes offering lo- cal information. The 1st programme broad- cast by NDR, for example, offers program- mes with different contents in the northern states of Germany
If you are tuned into a regional programme and wish to continue listening to this pro- gramme,
•press the AF button for approximately 2 seconds.
“REG ON” appears in the display.
If you leave the service area of the regional programme tuned into, or if you would like to take advantage of the full RDS service, switch to “REG OFF”.
•Press the AF button for approximately 2 seconds until “REG OFF” appears.
When active, “REG ON” will be briefly dis- played each time the radio is switched on.
Selecting a waveband
You can choose between the following wave- bands:
FM 87.5 - 108 MHz
MW 531 - 1602 kHz
LW 153 - 279 kHz
•Set the desired waveband by pressing FM·T or M·L.
To switch from MW to LW or vice versa
•press the M·L button.
Selecting a station
Using the 
buttons there are several different ways of tuning into a station:
