POWER button of the amplifier serves as the
central switch for all units connected to the AC
OUTLETS.
MUTING
To use this option, ensure that the POWER

RDS RADIO DATA SYSTEM
Your tuner is an RDS tuner.
RDS (Radio Data System) stands for a new
generation of radios that provides the listener
with more comfort and extra usefull information.
If you are tuned to an RDS station, the name of
the station will be indicated after a short time.
With the INFO button you can call up other RDS
services like RDS time and radiotext provided that
this information is transmitted (see page 20).
RDS Radio Data System
Your unit is capable of receiving and evaluating
RDS information which is broadcast along with
the normal broadcast signal. The channel name
is displayed and automatically stored in the unit´s
memory, overwriting names previously stored.
RDS TIME
Some RDS stations broadcast the 'RDS-TIME'
information. The time display is updated every
minute. The accuracy of the time depends on the
broadcasted information.
RADIOTEXT
More and more RDS stations broadcast
RADIOTEXT, which is additional information on
the station and programme being broadcast.
RADIOTEXT information appears as "running" text
in the display.
RADIOTEXT is transmitted character-by-character
by the radio station. As a result of that it may take
some time until the entire text has been
completely received.
Selecting the wave band
• Select the desired wave band (FM or MW) by
ANTENNA
pressing BAND.
• Pressing this button switches between the two
MHz
wavebands.
– The display shows the selected band.
kHz
Adapting the antenna
If you receive broadcasts via broad band cable
of a public or private cable service, there may be
high signal inputs at your antenna terminal, which
ANTENNA
may in turn cause reception disturbances.
MHz
• If this is the case, press the ANTENNA/CABLE
CABLE
button to switch on the input attenuator.
'CABLE' appears on the display.
MHz
This reduces the antenna input sensitivity, thus
reducing disturbances. The setting is
automatically stored after 5 seconds.
ANTENNA
FM reception STEREO/MONO
MHz
Normally, your unit is in stereo reception mode,
which means that as soon as a stereo signal of
sufficient strength is detected, 'STEREO' appears
in the display. If stereo reception is disturbed,
'STEREO' disappears. In this way, disturbing
background noise is suppressed.
• If noise-free stereo reception is not possible,
ANTENNA
you can switch your unit to MONO reception
by pressing MONO.
MHz
– MUTING will disappear from the display and
ANTENNA
MONO will appear.
The MUTING function is always switched off

for MONO reception, allowing the unit to
receive even very weak broadcast signals.

This button is used for switching the tuner on and off.
MONO/MUTE
You use this button for selecting mono reception if, for example, stereo reception
exhibits too much disturbing noise.
This simultaneously switches off the MUTING function.
BAND
This button is used to switch to the FM and MW bands.
TUNING # $
You use these buttons to start the station search (AUTO TUNING) or to advance
the frequency step by step (MANUAL TUNING). If you keep the button depressed,
station search is accelerated.
STATION # $
These buttons are used to scroll through the station memory in ascending (#) or
descending ($) order.
MEMORY
This button stores the actual station at the lowest empty memory location.
When pressing this button longer, the AUTO STORE function will be started.
CANCEL
This button is used to delete individual memory locations or, if desired, the
entire memory contents (by keeping the button depressed for more than 10 seconds).
ANTENNA/CABLE This button is used to switch on the antenna attenuator for reducing radio disturbance
if your tuner is connected to broadband cable and the reception signal is too strong.
PROG. TYPE ! @
These buttons are used to select the various programme types.
INFO
This button is used for switching the display between the station name (RDS), or
another name you assign, Radiotext, RDS time and station frequency.

This button is used for selecting the station name input mode.
TUNING
Automatic tuning
• To activate automatic station search (AUTO
TUNING), press TUNING # or $ until the
frequency display begins 'to run'; then release
the button.
– 'AUTO' appears on the display, and

disappears at the conclusion of the automatic
tuning function.
– The search stops as soon as a station with
sufficient reception quality is found and tuned
MUTING
to precisely. A triangle in the display lights up.
STEREO
– Every time you begin a search, the unit auto-
matically switches to STEREO.
– A bar graph in the display indicates the field
strength: the more illuminated dashes you see,
the stronger the reception.
– The frequency of the received station is
indicated in MHz (FM) or kHz (MW).
– If the search stops, the 'AUTO COMPARE'
function first verifies whether the station which
has been found is already stored in the station
memory. If this is the case, the memory
location of the station is displayed, as well as
the name of the station, if it already exists.
– Stations which are received with a weak field
strength may be skipped.
These can be tuned to manually.
• If desired, you can also interrupt the search by
pressing briefly TUNING # or $.
