Tuner Operation
RDS Operation
The AVR 147 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
advantage 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 Ò.
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, broad-
cast network or call letters. Pressing the RDS
button ^
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 (
) as shown in the list
PTY
below.
NOTE: Many stations do not transmit a specific
PTY. The display will show
, when such a
NONE
station is selected and PTY is active.
• A "text" message (Radiotext,
R T
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
will flash in the Information Display when RT is
selected.
• The current time of day (
). Note that it may
C T
take up to two minutes for the time to appear, in
that time the word
will flash in the infor-
TIME
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 Ò will show a

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
abbreviations used to indicate each PTY, along
with an explanation of the PTY:
