2007 DODGE GRAND CARAVAN radio

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 6 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. UNDERSTANDING YOUR INSTRUMENT PANEL 221

Tuning
Press the TUNE control up or down to increase or
decrease the frequency. If you press and hold the button,
the radio will continue to tune until you release the
button. The frequency will be displayed and continu-
ously updated while the button is pressed.
Radio Data System (RDS)
The Radio Data System allows radio broadcasting sta-
tions to send data signals on a subcarrier frequency
which is added to the stereo signal. RDS was developed
to give FM receivers user-friendly features, such as
Program Service name (PS) and Program Type (PTY).
Program Service name is typically used by the broad-
caster to display the station’s name or call letters, for
example  WNIC  . Typically these are 8 characters in
length and are displayed by the radio for those stations which are broadcasting this information. PTY (Program
Type) is used to characterize the station’s program ma-
terial, for example  Rock Music  .
PTY (Program Type) Button
Pressing this button once will turn on the PTY mode for
5 seconds. If no action is taken during the 5 second time
out the PTY icon will turn off. Pressing the PTY button
within 5 seconds will allow the program format type to
be selected. Many radio stations do not currently broad-
cast PTY information.

By pressing the SEEK button when the PTY icon is
displayed, the radio will be tuned to the next frequency
station with the same selected PTY name. The PTY
function only operates when in the FM mode.
The radio display will flash “SEEK” and the selected PTY
program type when searching for the next PTY station. If
no station is found with the selected PTY program type,
the radio will return to the last preset station.
If a preset button is activated while in the PTY (Program
Type) mode, the PTY mode will be exited and the radio
will tune to the preset station.224 UNDERSTANDING YOUR INSTRUMENT PANEL

stations to be locked into memory. You can recall the
stations stored in SET 2 memory by pressing the push-
button twice. To Change From Clock To Radio Mode
