If both P-TYPE and TRAF are on, the radio will search for stations with the selected PTY and traffic announcements. To use the PTY interrupt feature, press and hold the P-TYPE button until you hear a beep on the PTY you want to interrupt with. When selected, an asterick will appear beside that PTY on the display. You may select multiple interrupts if desired. When you are listening to a compact disc, the last selected RDS station will interrupt play if that selected program type format is broadcast. SCAN: You can also scan through the stations within a category by performing the following: 1. Press the P-TYPE button. P-TYPE and the last selected PTY will be displayed on the screen. 2. Select a category by turning the P-TYPE knob. 3. Once the desired category is displayed, press and hold either SCAN arrow, and the radio will begin scanning within your chosen category. 4. Press either SCAN arrow again to stop at a particular station. BAND (Alternate Frequency): Alternate frequency allows the radio to switch to a stronger station with the same program type. Press and hold BAND for two seconds to turn alternate frequency on. AF ON will appear on the display. The radio may switch to stronger stations. Press and hold BAND again for two seconds to turn alternate frequency off. AF OFF will appear on the display. The radio will not switch to other stations. When you turn the ignition off and then on again, the alternate frequency feature will automatically be turned on. This function does not apply for XM™.
