Adjusting the Speakers
ATC (Auto Tone Control): The
ATC feature is used to provide a
choice of six different listening
experiences. ATC can be used
while listening to the audio system
or the CD player. The audio system
can store separate ATC settings for
each source and preset station.
To save ATC settings for the preset
stations, use the SOUND menu and
press ATC. See Preset Stations
earlier in this section for more
information.
Radio Data System (RDS)
The audio system has a Radio
Data System (RDS). RDS features
are available for use only on FM
stations that broadcast RDS
information. With RDS, the
radio can do the following:
Seek to stations broadcasting
the selected type of
programming.
Receive announcements
concerning local and national
emergencies.
Display messages from radio
stations.
Seek to stations with traffic
announcements.
RDS (Radio Data System): Press
RDS to use alternate RDS functions
located in the preset menu. After
pressing RDS, quickly choose RDS
ON/OFF, TA, INFO, PTY, or Select
PTY. If a selection is not made,
the system returns to the
previous menu.
Infotainment System
If tuned to a station broadcasting
RDS information, the station's
Program Service (PS) and Program
Type (PTY) replaces the station's
frequency on the status line at
the top of the display. After about
five seconds, if available, the PTY
is replaced on the display by the
station's PTY name. The PTY and
PTY name can be the same or
different.
If the audio system is tuned to a
station that is not broadcasting RDS
information, the station's frequency
remains on the display.
The RDS feature relies upon
receiving specific information from
RDS stations. These features only
work when RDS information is
available.
