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.

FM ANTENNA CONNECTION

Owning to the high sensitivity of the FM
Tuner stage of the unit, the antenna wire
(twin-T" shape, window shead) 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-ohm
and G-terminal with the outer conductor or
shielding blade of the cable, or use the
coaxial adaptor socket marked 75-ohm.

GROUND

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 burried 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
amplifiers switched or unswitched AC out-
let. If it is connected to a switched outlet,
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 tuners own power button for
switching control.

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.

COAXIAL CABLE:

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 tuners front-end.
