Using Digital Signal Processing (DSP) DSP: This feature is used to provide a choice of four different listening experiences: talk, front seat, ambience and spacious. DSP can be used while listening to the radio, cassette, CD, or XM™. Press this button to turn DSP on. Press and release this button until the desired selection appears on the display. To turn DSP off, press and hold this button until DSP OFF appears on the display. When DSP OFF appears on the display, the system will provide the best overall audio performance. The radio keeps separate DSP settings for each band (except weather band, which is always set to talk), preset, and source. TALK: This setting should be used when listening to non-musical material such as news, talk shows, sports broadcasts, and books on tape. Talk makes spoken words sound very clear. FRONT SEAT: This setting adjusts the audio to give the driver the best possible sound qualities. Front seat can be used at any time for any material. Rear seat passengers in the vehicle may not get the same effect. AMBIENCE: This setting is used to enhance the stereo effect. SPACIOUS: This setting is used to make the listening space seem larger. 3-92 Finding a Program Type (PTY) Station (XM™ Only) To select and find a desired PTY perform the following: 1. Press PTY to activate program type select mode. PTY will appear on the display. 2. Press LEVEL to select a PTY. 3. Once the desired PTY is displayed, press either TUNE SEEK arrow to select the PTY and take you to the PTY's first station. 4. If you want to go to another station within that PTY, press TUNE SEEK once to display the PTY, then press TUNE SEEK again to go to another station. 5. Press PTY 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 TA are on, the radio will search for stations with the selected PTY and traffic announcements.
