2008 DODGE RAM 2500 GAS radio controls

NOTE:If you try to remove the key before you place the
lever in PARK, the key may become trapped temporarily
in the ignition cylinder. If this occurs, rotate the key to the
right slightly, then remove the key as described. If a
malfunction occurs, the system will trap the key in the
ignition cylinder to warn you that this safety feature is
inoperable. The engine can be started and stopped but
the key cannot be removed until you obtain service.
NOTE:The power window switches, radio, power
sunroof (if equipped), and power outlets will remain
active for 10 minutes after the ignition switch is turned
OFF. Opening either front door will cancel this feature.WARNING!
Never leave children alone in a vehicle. Leaving
unattended children in a vehicle is dangerous for a
number of reasons. A child or others could be seri-
ously or fatally injured. Don't leave the key in the
ignition. A child could operate power windows,
other controls, or move the vehicle.
CAUTION!
An unlocked car is an invitation to thieves. Always
remove key from the ignition and lock all doors
when leaving the vehicle unattended.

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.
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.
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.
