Operation

RDS Operation

The AVR is equipped with RDS (Radio Data
System), which brings a wide range of
information to FM radio. RDS is a system for
transmitting station call signs or network infor-
mation, a description of station program type,
text messages about the station or specifics of a
musical selection, and the correct time.

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

F.

RDS Display Options
The RDS system is capable of transmitting a
wide variety of information in addition to the
initial station call sign that appears when a
station is first tuned. In normal RDS operation
the display will indicate the station name,
broadcast network or call letters. Pressing the
RDS button

BF enables you to cycle

through the various data types in the following
sequence:

• The station’s call letters (with some private
stations 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
display 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

information 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

F will show

a

N O TYPE

,

N O TEXT

or

N O TIME

message 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.

You may search for a specific Program Type
(PTY) by following these steps:

1. Press the RDS button

BF until the

current PTY is shown in the Main Information
Display

F.

2. While the PTY is shown, press the Preset
Up/Down
button

9E or hold them pressed

to scroll through the list of available PTY types,
as shown above. To simply search for the next
station transmitting any RDS data, use the
Preset Up/Down button

9E until

RDS

ONLY

appears in the display.

3. Press any of the Tuning Up/Down buttons
7U, the tuner begins to scan the FM band
upwards or downwards for the first station that
has RDS data that matches the desired
selection, 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
acceptable 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 AVR will find the appro-
priate station, even if it is not broadcasting traf-
fic information when the search is made.
