RADIO GENERAL INFORMATION
Radio Broadcast Signals
The radio will provide excellent reception under most
operating conditions. Like any system, however, automo-
tive radios have performance limitations, due to mobile
operation and natural phenomena, which might lead you
to believe your sound system is malfunctioning. To help
you understand and save you concern about these “ap-
parent” malfunctions, you must understand a point or
two about the transmission and reception of radio sig-
nals.

Two Types of Signals
There are two basic types of radio signals: AM or
Amplitude Modulation, in which the transmitted sound
causes the amplitude, or height, of the radio waves to
vary; and FM or Frequency Modulation, in which the
frequency of the wave is varied to carry the sound.
Electrical Disturbances
Radio waves may pick up electrical disturbances during
transmission. They mainly affect the wave amplitude,
and thus remain a part of the AM reception. They
interfere very little with the frequency variations that
carry the FM signal.
AM Reception
AM sound is based on wave amplitude, so AM reception
can be disrupted by such things as lightning, power lines
and neon signs.
FM Reception
Because FM transmission is based on frequency varia-
tions, interference that consists of amplitude variations
can be filtered out, leaving the reception relatively clear,
which is the major feature of FM radio.
NOTE:The radio, steering wheel radio controls (if
equipped), and six-disc CD/DVD changer (if equipped)
will remain active for up to 10 minutes after the ignition
switch has been turned OFF. Opening a vehicle front
door will cancel this feature.
