Selecting a reception range
 
Radio waves Ñ medium wave, long 
wave and short wave Ñ offer a wide 
range of reception, because the broad-
cast signals travel not only along the 
ground as surface waves, but also as 
waves bounced back to earth from the 
ionosphere.
Frequency Modulation (FM) provides 
substantially better sound quality than 
Amplitude Modulation (AM). However, 
because FM transmissions rely on line-
of-sight broadcast waves, their effec-
tive reception range is limited.

RDS Ñ Radio Data System
 
Thanks to specially designed systems, 
limitations inherent in mobile reception 
quality have been partially minimized:
The Radio Data System (RDS) transmits 
information in the FM reception range. 
RDS stations thus offer the following 
characteristics:
 
>
 
The station name will be indicated in 
the display after the RDS signals 
have been evaluated
 
>
 
Additional information can be indi-
cated or called up in the display (e. g. 
text broadcasts from the station, 
PTY).
However, the reception of RDS data is 
only possible under favorable reception 
conditions. If there is weak or inter-
rupted reception, it can take quite a 
while before the transmitter name 
appears in the display.
 
Selecting a station
 
1. Switch on the RDS with
"RDS " will appear in the display 
along with the name of the current 
station, if it is broadcasting RDS 
information
2. Start the scan with 
Press or hold down.
The scan mode begins with the 
station that was last set.
The scan mode is stopped as soon 
as a station is found.
