Function Control
The DAB mode in the TU 970 contains a menu
structure to access various system options. To
enter the menu, press the Function Button on
the front panel 4 or on the remote control 
6
once. To scroll through the list of sections of the
menu, turn the Control Ring ) or press the

Select button 
!
8. You can scroll through
the options with the Control Ring and activate
an option by pressing the Select Button once
that option is shown on the Information
Display
.
Station Order
In this section you can select the way the station
list is displayed. The options are Favorite Station,
Alphanumeric, Active Station and Tidy Station.
The Favorite Station option will build the station
list based on the stations that you listen to most
of the time. These stations will be marked on the
Information Display with a “Y”-symbol. The
10 favorite stations will be moved to the start of
your station list, so you do not always have to
scroll through the whole list to find your favorite
station.
The Alphanumeric option is the default setting. It
will list the stations in numeric and alphabetical
order.
The Active Station option will sort the station list
by quality of the signal. The stations with the
best reception will be shown on top of the list.
Stations with weak or no reception will be
moved to the bottom of the list.
The Tidy Station option will do the same as the
Active Station option, but will remove the sta-
tions in your area with no reception.
Signal Error Rate
In this section you can see the level of correction
the TU 970 is applying to the DAB signal to
maintain the audio quality. The level will be indi-
cated by a numeric value between 0 (no correc-
tion) and 99 (maximum correction). For an
acceptable quality, the value of 50 should not be
exceeded.

Operation
Preset Tune
In this section you can tune presets of stations
that broadcast only periodically, stations which
were not found during the Autotune process. If
you return to this preset in the future, and at
that time is does not broadcast, the display will
show 
STATION NOT AVAILABLE
.
Software Version
This section allows a visual check of software
version installed in your TU 970. This might be
helpful in case servicing of your tuner may be
necessary.
Dynamic Range Control (DRC) Value
In this section you can set the level of compres-
sion of stations to eliminate the differences in
dynamic range or sound level between radio sta-
tions. Popular music would normally be more
compressed than classical music, resulting in
possible different audio levels when changing
from one station to the other. Setting the DRC to
0
means no compression,
1/2
indicates
medium compression and 
1
shows maximum
compression. No compression is recommended,
especially for classical music. Note that other
radio stations may be far louder, and make
therefore sure that amplifier levels are not set
too high when changing from one station to
another.
Manual Tune
In this section you can activate Manual Tuning,
in case the Autotune function is unable to find
any stations. You can also use Manual Tuning to
assist in positioning the antenna for best recep-
tion of a specific station.
FM/AM Tuner Operation
The TU 970’s tuner is capable of tuning AM, FM
and FM Stereo broadcast stations. Stations may
be tuned manually or automatically, or they may

4 on the front panel so that
the 
STEREO
indication changes to 
MONO

matically for the entire FM band. To automatical-
ly enter each station that may be tuned with
acceptable quality into the TU 970’s preset
memories, first select the FM band. Next, press
and hold the Memory Button 9

station frequency indication begins to increase.
Release the button and note that the tuner will
search the entire FM band, and stop briefly at
each station that has acceptable signal strength.
The TU 970 will automatically assign a preset
number to each station, and then search for the
next station.
NOTE: Using the automatic tuning mode in
areas with more than 30 FM stations will com-
pletely fill the preset memories, and overwrite any
previously memorized presets for either AM or
FM stations.

OPERATION  11
Operation
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:

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.
