If the station does not broadcast traffic
announcements, press the TRAF button and the
radio seeks to a station that does. When a station
that broadcasts traffic announcements is found,
the radio stops seeking and TRAF displays.
If no station is found that broadcasts traffic
announcements, No Traf displays.
If TRAF displays, press the TRAF button to turn
off the traffic announcements.
The radio plays the traffic announcement if the
volume is low. The radio interrupts the play
of a CD if the last tuned station broadcasts
traffic announcements.
