RDS Operation
The AVR is equipped with RDS (Radio Data
System), which brings a wide range of informa-
tion to FM radio. Now in use in many countries,
RDS is a system for transmitting station call signs
or network information, a description of station
program type, text messages about the station or
specifics of a musical selection, and the correct
time.
As more FM stations become equipped with RDS
capabilities, the AVR will serve as an easy-to-use
center for both information and entertainment.
This section will help you take maximum advan-
tage of the RDS system.
RDS Tuning
When an FM station is tuned in and it contains
RDS data, the AVR will automatically display the
station’s call sign or other program service in the
Main Information Display
Ú
.
RDS Display Options
The RDS system is capable of transmitting a
wide variety of information in addition to the ini-
tial station call sign that appears when a station
is first tuned. In normal RDS operation the dis-
play will indicate the station name, broadcast
network or call letters. Pressing the
RDS
button
@
N
enables you to cycle through the various
data types in the following sequence:
• The station’s call letters (with some private sta-
tions other information too).
• The station’s frequency
(FREQ)
.
• The Program Type
(PTY)
as shown in the list
below.
• A “text” message (Radiotext,
R T
) containing
special information from the broadcast station.
Note that this message may scroll across the dis-
play to permit messages longer than the eight
positions in the display. Depending on signal
quality, it may take up to 30 seconds for the text
message to appear; in that time, the word
TEXT
will flash in the Information Display when
RT is selected.
• The current time of day (
C T
). Note that it may
take up to two minutes for the time to appear, in
that time the word
TIME
will flash in the infor-
mation display when CT is selected. Please note
that the accuracy of the time data is dependent
on the radio station, not the AVR.
Some RDS stations may not include some of
these additional features. If the data required for
the selected mode is not being transmitted, the
Main Information Display
Ú
will show a
NO TYPE
,
NO TEXT
or
NO TIME
mes-
sage after the individual time out.
In any FM mode the RDS function requires a
strong enough signal for proper operation.
Program Search (PTY)
An important feature of RDS is its capability of
encoding broadcasts with Program Type (PTY)
codes that indicate the type of material being
broadcast. The following list shows the abbrevia-
tions used to indicate each PTY, along with an
explanation of the PTY:

, the tuner begins to scan the FM band
upwards or downwards for the first station that
has RDS data that matches the desired selec-
tion, and acceptable signal strength for quality
reception.
4. The tuner will make up to one complete scan
of the entire FM band for the next station that
matches the desired PTY type and has accept-
able reception quality. If no such station is
found, the display will read
NONE
for some
seconds and the tuner will return to the last FM
station in use before the search.
NOTE:
Many stations do not transmit a specific
PTY. The display will show
NONE
, when such a
station is selected and PTY is active.
NOTE:
Some stations transmit constant traffic
information. These stations can be found by
selecting TRAFFIC, the option in front of NEWS in
the list. The AVR will find the appropriate station,
even if it is not broadcasting traffic information
when the search is made.
