If the brackets are on the display and TRAF is not, you
can then 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, NO TRAFFIC will appear on the
display.
Your radio will play the traffic announcements 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.
This function does not apply to XM™ Satellite Radio
Service.
