Finding a Program Type (PTY) Station (RDS and XM™) To select and find a desired PTY perform the following: 1. Turn the P-TYPE knob to select a PTY. 2. Once the desired PTY is displayed, press the SEEK TYPE button to select and to take you to the PTY's first station. 3. To go to another station within that PTY, press the SEEK TYPE button twice to display the PTY and then to go to another station. 4. Press P-TYPE knob to exit program type select mode. IF PTY times out and is no longer on the display, go back to Step 1. If both PTY and TRAF are on, the radio will search for stations with the selected PTY and traffic announcements. If the radio cannot find the desired program type, NONE will appear on the display and the radio will return to the last station you were listening to. BAND (Alternate Frequency): Alternate frequency allows the radio to switch to a stronger station with the same program type. To turn alternate frequency on, press and hold BAND for two seconds. AF ON will appear on the display. The radio may switch to stations with a stronger frequency. To turn alternate frequency off, press and hold BAND again for two seconds. AF OFF will appear on the display. The radio will not switch to other stations. This function does not apply for XM™ Satellite Radio Service. RDS Messages ALERT!: Alert warns of local or national emergencies. When an alert announcement comes on the current radio station, ALERT! will appear on the display. You will hear the announcement, even if the volume is low or a CD is playing. If a CD is playing, play will stop during the announcement. Alert announcements cannot be turned off. ALERT! will not be affected by tests of the emergency broadcast system. This feature is not supported by all RDS stations. 3-84
