Using RDS
Your audio system is equipped with a Radio Data

features. With RDS, the radio can do the following:

Seek only to stations with the types of programs you
want to listen to,

seek to stations with traffic announcements,

receive announcements concerning local and
national emergencies, and

receive and display messages from radio stations.
RDS features are only available for use on FM stations
which broadcast RDS information. The RDS features of
your radio rely upon receiving specific RDS information
from these stations. These features will only work when
the RDS information is available. In rare cases, a radio
station may broadcast incorrect information that will
cause the radio features to work improperly. If this
happens, please contact the radio station.
When you are tuned to an RDS station, the station
name will appear on the display, instead of the
frequency. Most RDS stations provide their station
name, the time of day and a Program Type (PTY) for
their current programming.P-TYPE: This button is used to turn on and off
Program Type (PTY) selections. PTY and the light next
to the button will turn on. The last selected PTY will
appear on the display for five seconds.
Turn the TUNE RCL P
-TYPE control to select the PTY
you want to listen to. Press the SEEK SCAN arrows to
find radio stations for the PTY you want to listen to. The
last PTY selected will be used for seek or scan modes.
If a station with the selected PTY is not found, NONE
FOUND will appear on the display. If both P
-TYPE and
TRAF are on, the radio will search for stations with
traffic announcements and the selected PTY.
To use the P
-TYPE interrupt feature, press and hold the
P
-TYPE button until you hear a beep on the PTY you
want to interrupt on. When you are listening to a compact
disc, the last selected RDS FM station will interrupt play
if that selected program type format is broadcast.

frequency feature. Alternate frequency allows the radio
to switch to a stronger station with the same program
type. Press and hold AM FM for two seconds to turn

of the message faster than every three seconds, press this
button again. A new group of words will appear on the
display. Once the complete message has been displayed,
INFO will disappear from the display until another new

announcements. The traffic announcement brackets will
appear on the display. TRAF will appear on the display
if the tuned station broadcasts traffic announcements.
If the current tuned station does not broadcast traffic
announcements, the radio will seek to a station that
does. When the radio finds a station that broadcasts
traffic announcements, it will stop. If no station is found,
NONE FOUND will appear on the display.
When a traffic announcement comes on the tuned radio
station or a related network station, you will hear it,
even if the volume is muted or a compact disc is
