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 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 this button. Once the complete message
has been displayed, the information symbol 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.
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 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 TRAF will appear on the display. If no station
is found that broadcasts traffic announcements, No Traf
will appear on the display.
If TRAF is on the display, press the TRAF button to turn
off the traffic announcements.
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.
This function does not apply to XM™ Satellite Radio
Service.
