If, however, as is often the case with community antennas, a
cable for the AM range is present then thisshould be connected
to the binding posts AM and GND. The antenna switch located
above the binding posts should be switched to FM.
Right next to these connections are a coax antenna jack and a
binding post for directly connecting 60/75 Ohm coax cables.
Coax cables offer the best protection against noise and ignition
interference. When connecting a 60/75 Ohm antenna, place the
antenna switch in the FM/AM position.
Connection to the amplifier
There are 3 jacks on the rear.
With the enclosed connecting lead, the DIN jack provides the
as solution if the amplifier has a corresponding radio input
jack.
Via the cynch jacks VARIABLE
R/L and the connecting lead
(Dual no. 226817) which can be obtained as aspecial accessory,
the tuner can be connected
to amplifiers with cynch input.
The radio signal applied to the DIN jack and the top cynch
jacks can be adjusted with the OUTPUT
LEVEL
control on
the front.
Choose the control position which provides the same volume
as the one obtained with a turntable or tape recorder.
For tape recordings, a tape recorder can also be connected to
_the cynch jacks FIXED R/L.
Initial operation
Station and frequency range selection
FM=87.50 — 104 mHz
AM =513 — 1602 kHz
The HiFi receiver has a precise quartz synchronized tuningunit,
which makes it possible to set the station frequency exactly.
For this purpose, the unit has a 5-position digital frequency
display instead of a frequency scale.
For tuning to an FM transmitter the keys FM and MAN should
be pressed. Should the desired station be located at a frequency
higher than the one displayed, press the key marked TUNING
UP until the desired frequency appears in the display window.
Should, however, the desired station be lower than the fre-
quency
displayed,
press
the key marked
TUNING
DOWN.
"Should the key TUNING
QUICK be simultaneously pressed
with either the TUNING
DOWN
or TUNING
UP keys, then
the frequency display on the tuning unit moves quickly to the
upper or lower frequency ranges.
By shortly pressing the keys TUNING UP or TUNING DOWN
the frequency change is made in steps of 50 kHz (0.05 MHz).
These steps correspond to the internationally normed frequency
grid for FM stations. The exact transmitting frequencies of the
desired stations can be taken from the program guides or from
the included transmitter table.
In addition to the digital frequency display the LED units
SIGNAL and CENTER TUNING serve to provide an exact and
distortion-free tuning. The LED unit SIGNAL shows the input
signal strength. The scale is logarithmic. In this way, it is pos-
sible to adjust a rotary antenna for optimum reception. The
stronger the signal level, the more LED'sare lit. The LED unit
CENTER
TUNING
displays additionally the correct center
tuning for FM stations. At exact center the green LED should
light.
In order to select an AM station, proceed in the same manner.
In this case, the keys AM and MAN are to be pressed. The dis-
play is made in steps of 1 kHz.
FM SCAN
VHF
range
Medium-wave range
By pressing the key FM SCAN DOWN the tuning unit tunes
automatically to the next lower frequency station and remains
there. Should you desire a further station, simply press the FM
SCAN
DOWN
key again. It is only necessary to tap the key
shortly in each case.
For stations lying above the frequency set, use the FM SCAN
UP key.
Programming the fixed station keys
Your HiFi tuner offers the possibility of programming each
fixed station key to a station in the FM range as well as to a.
station in the AM range.
Once you have manually selected the desired station it can be.
stored. To do this, press the MEMORY
key and the fixed sta-
tion key 1 simultaneously. At the same time, make sure that
the MEMORY button is pressed first. The station is thusstored
in the fixed station key 1 and can at any time be selected. The
fixed station keys 2 to 6 can be programmed in the same manner.
Switching from one of the fixed station keys to manual tuning
is made by pressing the MAN key.
The programming of the station memory buttons is automati-
cally deleted in the case of a long mains failure. Reset these in
accordance with the description below.
STEREO TRIGGER
The tuner has a circuitry which automatically switches over
stereo transmissions to mono
if the antenna signal does not
reach a certain value. At the same time, the MODE switch must
be inSTEREO position.
The switchover
point can
be individually adjusted with the
rotary control STEREO -TRIGGER.
If in full right hand
position, all stereo transmitters with an
antenna signal of more than 10 HV are reproduced in stereo
and, if in full left hand position, transmissions are only repro- |
duced
in stereo if they have an antenna signal of more than
280 uV.
Adjust the control
in such a way
that switchover just takes
place with
transmitters
which
can
no longer be received in
stereo without noise. The LED display SIGNAL helps you to
judge the reception quality of transmissions.
If the MODE
switch is in MONO
position, all stereo transmissions are re-
produced
monaurally,
indpendently
of the position
of the
rotary control.
MUTING switch/MUTING TRIGGER
CLOCK/time display
RECORD TEST
When the RECORD TEST switch is in ON position, the tuner -
emits a long test tone whose intensity can be influenced with
the rotary control OUTPUT
LEVEL. A tape recording can be
