INSTALLATION
First, make sure that all the necessary
connections are properly made.

AM ANTENNA CONNECTION

No external antenna will generally be re-
quired for AM broadcast listenings, since a
ferrite loopstick antenna is supplied at the
rear of the unit. For best possible reception,
extend the loopstick fully away from the
tuner chassis.

If you live in a difficult reception area, the
use of an external or outdoor antenna may
be desireable.

Connect a single wire antenna lead to the
terminal marked AM on the rear chassis.
The single wire antenna ("hay" or a kind of
"whip") should then be longer as possible,
and oriented for best reception, It must be
kept away from large metal objects, power
lines or electrical machinery to insure better
reception to avoid extraneous noises.

AM ANTENNA

FM ANTENNA CONNECTION

Owning to the high sensitivity of the FM
Tuner stage of the unit, the antenna wire
(twin~T" shape, window sheadl supplied is
sufficient for most locations.

Connect this feed line ends to both termi-
nals marked 300 ohms; FM ANT, and
mount this twin-T horizontally, for ex-
ample, by tacking both ends to the shelf
front edge on which the receiver is located.
In case weak signal area, the use of an
outdoor type exclusive FM antenna may
prove necessary. Follow its instructions for
proper connections.

When using a 75-ohm unbalanced coaxial
cable to feed signals from antenna, connect
them to terminal posts marked a 75 and G-terminal with the outer conductor or
shielding blade of the cable, or use the
coaxial adaptor socket marked 75-ohm.

however, if you wish to take the tuner to be

earthed to eliminate unwanted noises possi-
ble, connect a wire from the terminal
designated GND on the rear chassis to the
ground terminal on your amplifier or to a
nail hurried under ground.

AC POWER INPUT CORD (AC MAINS)
Your tuner has been specially designed so
that it may be connected to a variety of
power sources. You may connect the AC
Power Input Cord directly to a wall outlet
in case when the power will be supplied to
the tuner independently from your ampli»
fier. Or, you may connect it to your
amplifier's switched or unswitched AC out-
let. If it is connected to a switched( t,
by leaving the power button of the tuner
on, you will be able to maintain switching
control for the tuner with your amplifier
together. If it is connected to an unswitched
outlet, like connecting to a wall outlet you
must use the tuner's own power button for
switching control.

AM FERRITE BAR ANTENNA

Toobtain the best possible reception on AM
broadcast swing the AM ferrite antenna
away from the receiver chassis as far as it
will go without forcing it. In doing this it is
very necessary to note to keep all speaker,
audio, and power cables away from this
antenna and never use it as a handle.

STEREO INDICATOR LIGHT: auto-
matically lights up on the dial glass to
visually indicate whenever an FM stereo
broadcast is tuned in.

SIGNAL TUNING METER:

shows the level of the incoming signal. When
used with the TUNING KNOB tune for maximum
pointer deflection to the right for best possible
reception of AM broadcast. For FM tuning. when
meter read zero at the center of the scale'that
indicats the proper and sharpest tuning of FM.

FUNCTION SELECTOR CONTROL:
enables you to select the program you desire
from AM, FM, and FM STEREO.

POWER SWITCH: supplies power to the
tuner. When the switch is ON, dial scale will
be illuminated.

HIGH BLEND FILTER SWITCH: allows
you to reduce annoying noise mixed in with
signal. This switch, however, should not
always be left at W position unless it is very
necessary.

CONNECTING TO POWER SUPPLY

Prior to connection ensure that the voltage
selector is set correctly for your local AC
mains supply, and a suitable plug fitted. If
you need to fit a plug, make sure also that a
live, neutral and (where appropriate) earth
leads are connected to the proper terminals.
If in any doubt about connection to the
mains supply, consult a qualified technician.

MUTING SWITCH: in an IN position acti-
vates a circuit which reduces audible inter-
station noise when tuning from station to
station in FM band. Since very weak signals
may be muted at the same time, leave the
switch. in OUT position when you wish to
pick up a very weak station.

TUNING KNOB.
TUNING DIAL KNOB: a heavy flywheel

.action allows you to obtain the easy and

precise tuning both on FM and AM broad~
casts.

COAXIAL CABLE: Mate and plug in the
cable connector to a chassis socket of the
tuner firmly and gently tighten the outer
connector cover turning it clockwise.
Advantage of using coaxial cable is to shut
off external noise fed_through feed line
which usually affects tuner's front-end.
