Interior Comfort

Audio System

Form No. 8S18-EA-03I

Flutter/Skip noise

Signals from an FM transmitter move in 
straight lines and become weak in valleys 
between tall buildings, mountains, and 
other obstacles. When a vehicle passes 
through such an area, the reception 
conditions may change suddenly, 
resulting in annoying noise.

Weak signal noise

In suburban areas, broadcast signals 
become weak because of distance from 
the transmitter. Reception in such fringe 
areas is characterized by sound breakup.

Strong signal noise

This occurs very close to a transmitter 
tower. The broadcast signals are 
extremely strong, so the result is noise and 
sound breakup at the radio receiver.

Station drift noise

When a vehicle reaches the area of two 
strong stations broadcasting at similar 
frequencies, the original station may be 
temporarily lost and the second station 
picked up. At this time there will be some 
noise from this disturbance.

Station 1
88.1 MHz

Station 2
88.3 MHz
