Knowing your Vehicle 
 
How vehicle audio works AM and FM radio signals are broadcast from transmitter towers located around your city. They are intercepted by the radio antenna 
on your vehicle. This signal is then received by the radio and sent to your vehicle speakers. 
 
When a strong radio signal has reached your vehicle, the precise engineering of your audio system ensures the best possible quality reproduction. However, in 
some cases the signal coming to your vehicle may not be strong and clear. This can be due to factors such as the distance from the radio station, closeness of 
other strong radio stations or the presence of buildings, bridges or other large obstructions in the area.   
 
AM broadcasts can be received at greater distances than FM broadcasts. This is because AM radio waves are transmitted at low frequencies. These long, low 
frequency  radio  waves  can  follow  the  curvature  of  the  earth  rather  than  travelling  straight  out  into  the  atmosphere.  In  addition,  they  curve  around 
obstructions so that they can provide better signal coverage. 
 
FM broadcasts are transmitted at high frequencies and do not bend to follow the earth's surface. Because of this, FM broadcasts generally begin to fade at 
short  distances  from  the  station.  Also,  FM  signals  are  easily  affected  by  buildings,  mountains,  or  other  obstructions.  These  can  result  in  certain  listening 
conditions which might lead you to believe a problem exists with your radio. The following conditions are normal and do not indicate radio trouble: 
 
•  Fading - As your vehicle moves away from the radio station, the signal will weaken and sound will begin to fade. When this occurs, we suggest that you 
select another stronger station. 
•  Flutter/Static - Weak FM signals or large obstructions between the transmitter and your radio can disturb the signal causing static or fluttering noises 
to occur. Reducing the treble level may lessen this effect until the disturbance clears. 
•  Station  Swapping  -  As  a  FM  signal  weakens,  another  more  powerful  signal  near  the  same  frequency  may  begin  to  play.  This  is  because  your  radio  is 
designed to lock onto the clearest signal. If this occurs, select another station with a stronger signal.   
•  Multi-Path Cancellation - Radio signals being received from several directions can cause distortion or fluttering. This can be caused by a direct and reflected 
signal from the same station, or by signals from two stations with close frequencies. If this occurs, select another station until the condition has passed.
