ALERT! will not be affected by tests of the emergency
broadcast system. This feature is not supported by
all RDS stations.
INFO (Information): If the current station has a
message, INFO will appear on the display. Press this
button to see the message. The message may display
the artist, song title, call in phone numbers, etc.
If the entire message is not displayed, parts of the
message will appear every three seconds. To scroll
through the message, press and release the INFO button.
A new group of words will appear on the display after
every press of the button. Once the complete message
has been displayed, INFO will disappear from the display
until another new message is received. The last message
can be displayed by pressing the INFO button. You can
view the last message until a new message is received or
a different station is tuned to.
TRAF (Traffic): If TRAF appears on the display, the
tuned station broadcasts traffic announcements.
To receive the traffic announcement from the tuned
station, press this button. Brackets will be displayed
around TRAF and when a traffic announcement comes
on the tuned radio station you will hear it.
If the station does not broadcast traffic announcements,
press the TRAF button and the radio will seek to a
station that does. When a station that broadcasts traffic
announcements is found, the radio will stop seeking
and brackets will be displayed around TRAF. If no
station is found that broadcasts traffic announcements,
NO TRAFFIC will appear on the display.
If the brackets are on the display and TRAF is not,
press the TRAF button to remove the brackets or
use the TUNE knob or the SEEK arrows to go to a
station that supports traffic announcements. If no
station is found that broadcasts traffic announcements,
NO TRAFFIC will appear on the display.
The radio will play the traffic announcement if the
volume is low. The radio will interrupt the play of a CD if
the last tuned station broadcasts traffic announcements
and the brackets are displayed.
This function does not apply to XM™ Satellite
Radio Service.
