SELECTING THE FREQUENCY BAND
 
With your car radio you can receive the 
following reception ranges: FM and AM.
The frequency range AM allows the recep-
tion of distant stations because the broad-
cast signals not only travel along the 
ground as surface waves, but also as waves 
bounced back to earth from the iono-
sphere.
Frequency Modulation (FM) provides 
substantially better sound quality than 
Amplitude Modulation (AM). However, 
because FM transmissions rely on line-
of-sight broadcast waves, their effective 
reception range is limited.
 
Select the waveband
With touch actuations of FM you 
switch between the FM memory 
areas FM1, FM2 and FMA (Autostore).
With touch actuations of AM you switch 
between the AM memory areas AM and 
AMA (Autostore).
