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 current tuned station does not broadcast traffic announcements, press the TRAF 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 brackets will be displayed around TRAF. When a traffic announcement comes on the tuned radio station you will hear it. If no station is found, NO TRAFFIC will appear on the display. 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 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. Radio Messages CAL (CALIBRATE): Your audio system has been calibrated for your vehicle from the factory. If CAL appears on the display it means that your radio has not been configured properly for your vehicle and must be returned to the dealer for service. Playing a Cassette Tape You tape player is built to work best with tapes that are up to 30 to 45 minutes long on each side. Tapes longer than that are so thin they may not work well in this player. The longer side with the tape visible should face to the right. If the ignition and the radio are on, the tape can be inserted and will begin playing. If you hear nothing or hear a garbled sound, the tape may not be in squarely. Press the eject button to remove the tape and start over. While the tape is playing, use the VOLUME and AUDIO controls just as you do for the radio. The display will show an arrow to show which side of the tape is playing. If you want to insert a tape while the ignition or radio is off, first press the eject or DISP button. Cassette tape adapter kits for portable CD players will work in your cassette tape player. 3-58
