 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 com-
puter 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 front-
panel Function/FM Mode Button.
