Using DSP
DSP (Digital Signal Processing): 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, the cassette tape player or the
CD player. 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
is displayed, 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.

Using RDS
Your audio system is equipped with Radio Data Systems
(RDS). RDS mode gives you many useful new features.
With RDS the radio can:
D
seek to stations with traffic announcements,
D
receive announcements concerning local and
national emergencies,
D
receive and display messages from radio stations and
D
search for a stronger station when a station is too
weak for listening.
RDS features are only available for use on FM stations
which broadcast RDS information.
RDS (Radio Data Systems): If you are tuned to a
station broadcasting RDS information, the station's call
letters and Program Type (PTY) will replace the
station's frequency on the display. After five seconds,
the program type will be replaced on the display by the
station's program type name. The program type and
program type name may be the same or different. Press
BAND to recall the frequency and program type
displays. If the radio is tuned to a station that is not
broadcasting RDS information, the station's frequency
will remain on the display. With RDS the radio will
search for a stronger station in the network when a
station gets too weak for listening.
