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.
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.
Press The RDS feature relies upon
receiving specific information from
RDS stations. These features only
work when RDS information is
available.
Press TA to receive traffic
announcements. TA displays if the
current station broadcasts traffic
announcements. If the current
station does not broadcast traffic
announcements, the audio system
seeks to a station that does and
stops. If no station is found, TA
turns off.
While a traffic announcement plays,
the audio system uses TA volume.
To increase TA volume, use the
VOL up or down buttons during the
announcement. See Guidance
Volume under
for more information.
