Power Indicator: This LED will illuminate in
amber when the unit is in the Standby mode to
signal that the unit is ready to be turned on.
When the unit is in operation, the indicator will
turn blue.
1
System Power Control: Press this button
to turn on the TU 980; press it again to turn the
unit off (to Standby). Note that the Power Indi-
cator
next to the switch will turn blue when
the unit is on.
2
Band Selector: Press this button to change
between the DAB, FM and AM frequency bands.
3
Function/FM Mode Selector: In DAB
mode, pressing this button will activate station
order, preset tune, Dynamic Rate Control or
manual tune features. In FM mode, press this
button to select the stereo or mono mode for
FM tuning. In the stereo mode, the word
STEREO
will be shown in the Information
Display
6
, and stereo reception will be
provided when stations are transmitting stereo
signals. In the mono mode, the left and right
signals from stereo broadcasts will be mixed
together and reproduced through all channels.
Select
MONO
for better reception of weak
signals.
4
Info/RDS Button: In DAB mode, pressing
this button will change the content of the lower
display line of the Information Display as shown
on page 9, as well as signal error rate and software version. In RDS mode, it will change
between the different RDS options.
5
Auto Tune Button: In DAB mode, press this
button to automatically scan all available
stations.
6
Information Display: This dual line display
delivers messages and status indications to help
you operate the tuner.
7
Dimmer: Press this button to dim the front
panel display. The first press of the button will
dim the displays to one-half normal brightness;
the next press will turn off the display. Press the
button again to turn the displays back to normal
brightness.
The display will return to normal brightness the
next time the unit is turned on.
8
Memory Button: Press this button to open
the memory position that stores a preset
location in the tuner. 99 DAB presets can be
stored, as well as 30 FM and 30 AM presets.
(See page 9 for more information on tuner
presets.)
9
Control Ring: Turn counterclockwise to
tune lower frequency stations and clockwise to
tune higher frequency stations. When a station
with a strong signal is tuned, the Information
Display
6
will read
TUNED
. Turn again to
tune to the next frequency increment in ManualTune Mode, or automatically to the next
station with a signal strong enough for
acceptable reception in Auto Tune Mode.
The ring also controls the parameters in the
different menus.
A Select: In FM or AM mode, press this
button to select Auto Tune, Manual Tune or
Preset Tune. In DAB mode, press this button to
select the displayed station.
B
Remote Sensor Window:The sensor
behind this window receives infrared signals
from the remote control. Aim the remote at this
area and do not block or cover it unless an
external remote sensor is installed.

Optical and Coaxial Digital Outputs:
Connect one of these jacks to the optical or
coaxial digital input of your pre amplifier or
integrated amplifier, if available.
Note that these digital outputs only contain the
digital signal from the DAB stations. For FM/AM
reception, you will have to connect the analog
outputs at all times.
FM Antenna: Connect an indoor or exter-
nal FM antenna to this terminal.
AM Antenna: Connect the AM loop
antenna supplied with the receiver to these
terminals. If an external AM antenna is used,
make connections to the AM and GND
terminals in accordance with the instructions
supplied with the antenna.
Analog Audio Outputs: Connect these
jacks to the tuner input of your pre amplifier or
integrated amplifier for analog audio playback.
Be certain to observe proper channel
connections using the color-coded cables and
connectors so that red connects right channels
and white connects left channels.
NOTE: Before making any audio connections,
unplug all components of your audio system
from their AC power outlets. To reduce the
possibility of hum or noise in your system, place
all audio interconnection cables away from both
AC power cords and speaker wires.
DAB Antenna: Connect a DAB antenna to
this terminal.
AC Power Cord: Connect this plug to an
AC outlet. If the outlet is controlled by a switch,
make certain that it is in the ON position.
Remote Control Output: Connect this
jack to the infrared (IR) input jack of another
compatible Harman Kardon remote controlled
product to have the built-in Remote Sensor on
the tuner provide IR signals to other compatible
products.
Remote Control Input: Connect the
output of a remote infrared sensor, or the
remote control output of another compatible
Harman Kardon product, to this jack. This will
enable the remote control to operate even when
the front panel Remote Sensor on the tuner is
blocked. This jack may also be used with
compatible IR remote control-based automation
systems.
Software Update and Reset Button
(for Service Stations Only): This specialized
connector may be used with your personal computer in case Harman Kardon offers a software
upgrade for the tuner at some time in the
future. The Reset Button is only used during a
software upgrade. A standard processor reset is
performed by pressing and holding the frontpanel Function/FM Mode Button.

12 TROUBLESHOOTING GUIDE
Troubleshooting Guide
This unit is designed for trouble-free operation. Most problems users encounter are due to operating errors. If you have a problem, first check this list for a
possible solution. If the problem persists, consult your authorized Harman Kardon Service Center.
If the problem is...Make sure that the...
No lights appear when System Power button is pressedUnit is plugged into a live outlet.
Make sure the outlet is active.
No sound is heardTune to an active station.
Check for correct amplifier settings.
Check the connections and wires.
Sound distorts, particularly in stereo mode.Use a more directional antenna.
Intermittent or continuous buzzing or hissing.Place the unit farther away from these appliances. Install noise filters on the appliances.
Display says 'No stations Available'Check that antenna is connected.
Ensure that DAB coverage exists in your area.
Display has gone blank or says 'service off air'This may occur if a broadcaster changes the label of a service or removes a label whilst you
are listening to it. Try to retune to this station, using the Autotune procedure.
