RDS Messages
ALERT!: Alert warns of local or national emergencies.
When an alert announcement comes on the current
radio station, ALERT! will appear on the display. You will
hear the announcement, even if the volume is muted
or a cassette tape or CD is playing. If a cassette tape or
CD is playing, play will stop during the announcement.
You will not be able to turn off alert announcements.
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, the information symbol 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 whole message is not displayed, parts of the
message will appear every three seconds. To scroll
through the message at your own speed, press
the INFO button repeatedly. A new group of words will
appear on the display with each press. Once the
complete message has been displayed, the information
symbol will disappear from the display until another
new message is received. The old message can be
displayed by pressing the INFO button. You can view an
old message until a new message is received or a
different station is tuned to.
When a message is not available from a station, NO
INFO will appear on the display.
TRAF (Traffic): If TRAF appears on the display, the
tuned station broadcasts traffic announcements
and when a traffic announcement comes on the tuned
radio station you will hear it.
If the current tuned station does not broadcast traffic
announcements, press this button and the radio
will seek to a station that does. When the radio finds a
station that broadcasts traffic announcements, the
radio will stop and TRAF will be displayed. When a
traffic announcement comes on the tuned radio station
you will hear it. If no station is found, NO TRAF will
appear on the display.
If TRAF is on the display you can press the TRAF
button to turn of the traffic announcements.
Your radio will play the traffic announcement even if the
volume is low. Your radio will interrupt the play of a
cassette tape or CD if the last tuned station broadcasts
traffic announcements.
