RDS Operation
The AVR 3500 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 3500 will serve as an easy-
to-use center for both information and enter-
tainment. This section will help you take maxi-
mum advantage of the RDS system.
RDS Tuning
When an FM station is tuned in and it contains
RDS data, the RDS Indicator
W
will illuminate
and the AVR 3500 will automatically display the
station’s call sign or other program service in the
Main Information Display
N
.
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 sta-
tion is first tuned. In normal RDS operation the
display will indicate the station name, broadcast
network or call letters. Pressing the RDS button
@
P
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.
• The Program Type (PTY) as shown in the list
below.
• A “text” message (Radiotext, RT) 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 (CT). 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
3500.
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
N
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. If
you receive a partial message, or the RDS
Indicator
W
going on and off, try slowly
adjusting the antenna or tune to another
stronger RDS station.
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:
