RDS Operation
RDS (Radio Data System) transmits station call
signs or network information, 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 TU 970 will automatically display
the Program Service, which is the station’s call
sign, in the lower display line of the
Informa-
tion Display
, with some private stations also
offering other information changing every 2 to 5
seconds.
RDS Display Options
When an RDS station is tuned, press the
RDS
Button
on the remote control
3
or on the
front panel
5
to cycle through the RDS
displays in the following order:
• The Program Service or Station Name.
• The current time of the day
CLOCK TIME
as transmitted by the station. It will take 3-5
seconds for the time to appear. In the meantime
the word
RDS CLOCK TIME
will flash in
the display. Note that the accuracy of the time
message is set by the radio station, not by the
TU 970.
• The Program Type (PTY) as shown in the fol-
lowing list in this manual.
• A Radio Text message, containing special
information from the broadcast station. Note
that this message will scroll across the display to
permit messages longer than the positions in the
display. It will take 3 seconds for the text message
to appear, in the meantime the word
RDS
RADIO TEXT
will flash in the display. If no
Radio Text is available, the display will show the
Program Service (Station Name).
• Traffic Announcement. When selected,
TRAFFIC ANNOUNCE
will blink for 3
seconds. After 3 seconds, the tuner will scan the
FM band searching for available traffic
announcements.
• The station’s frequency. Some RDS stations
may not choose to include some of these addi-
tional features. If the data required for the
selected mode is not being transmitted, the
Information Display will show a
N O PTY
,
N O
TEXT
or
N O TIME
message after the indi-
vidual time out or will switch back to the previ-
ous display.
• In any FM mode the RDS function requires a
strong enough signal for proper operation. If you
receive a partial message or see any RDS indica-
tor going on and off, try slowly adjusting the
antenna to improve the signal strength or tune
to another, stronger, RDS station.
Program Search (PTY)
A major benefit of RDS is its ability to encode
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:

NOTE:
Many stations do not transmit a specific
PTY. The display will stay blank when such a sta-
tion is selected and PTY is active.
Processor Reset
In the rare case where the unit’s operation or the
displays seem abnormal, the cause may involve
the erratic operation of the system’s memory or
microprocessor.
To correct this problem, first unplug the unit
from the AC wall outlet and wait at least three
minutes. After the pause, reconnect the AC
power cord and check the unit’s operation. If the
system still malfunctions, a system reset may
clear the problem.
To reset the TU 970, press and hold the
Func-
tion/FM Mode Button
4
for 5 seconds, until
the
Information Display
shows
FACTORY
RESET
.
Note that when the system is reset, all tuner
presets will be lost and must be reentered.
If the system is still operating incorrectly, there
may have been an electronic discharge or severe
AC line interference that has corrupted the
memory or microprocessor.
If these steps do not solve the problem, consult
your dealer or an authorized Harman Kardon
service center.
