AM ANTENNA CONNECTION
Move the AM bar antenna on the rear panel of the
receiver and find the best reception position, all
the while following the instructions
outlined on
page 13 under 'AM RECEPTION.'
Fig. 8
NOTES:
e
The
AM
bar
antenna
on
the
receiver's
rear
panel
displays directivity and so some stations may be poorly
received.
In such cases,
change
the installation direc-
tion of the receiver.
e
If the receiver is installed right up against a wall in a
reinforced
concrete
building,
the
reception
may
be
adversely affected. Therefore, it is a good idea to erect
an indoor AM antenna.
e If you still cannot obtain good reception even
by moving the AM bar antenna, erect an indoor
AM antenna with a vinyl insulated wire (about
5-6 meters long). As shown in Fig.9, connect
the lead wire to the AM antenna terminal, and
tape it to the wall or ceiling.
e If you live in an area where the reception is poor
even if you erect an indoor AM antenna, use a
tree to erect an outdoor
AM
antenna
with a
vinyl insulated wire (Fig. 9).

GROUNDING
As shown in Figs.6 &
7, connect a ground wire to
the GND
terminal
on the receiver for maximum
safety and noise reduction. Never make this con-
nection
near
gas
pipes
and
other
potentially
dangerous locations.
FM ANTENNA LOCATION
It is important to choose with care the locations
where
you will install your
FM antenna for the
stable reception of the signals from FM broadcast-
ing stations and for superior sound reproduction.
Bear in mind the following points and determine
the optimum location (height and direction).
1. The
ideal place for the antenna is somewhere
where
it can
pick up the signals transmitted
from
the
FM
broadcasting
station
antenna
directly. Locations where these signals cannot be
picked up directly because of obstacles in their
path or because the receiver's antenna is located
in a low building surounded by higher buildings,
are
affected
by
the
multipath
effect
caused
when
signals
are reflected
off these
obstacles
or buildings. In such places, the sound will be
distorted
and the separation
between
the left
and right channels will deteriorate.
Choose a height and a direction for the antenna
where the multipath effect will be minimal.
2. Erect your antenna as far away as possible from
roads so that there is no interference from auto-
mobile ignition noise, and also from high-tension
power lines and neon signs.
38. Keep
your
antenna
at least two
meters
away
from
sheet-metal roofs, concrete buildings and
TV antennas.
Station direction
More than 4 meters
(15 ft.) above ground
Feeder or cable
should not directly
contact other structures.
Keep cabling
as short as possible
Select location away
from traffic noise
and with clear line of sight
