FM antennas
Since FM broadcast signals travel along a straight, direct-
line path, they become rather weak behind hills and build­
ings even in the vicinity of a broadcasting station . FM sig­
nals also become weak in areas distant from a station even
though there may not be any obstruction to the direct-line
path of the signal. Therefore, a good FM antenna should be
installed in the most effective manner for best possible FM
reception.

FM outdoor antenna
In areas at a greater distance from the transmitting station,
the use of an outdoor antenna is highly recommended. It is
available in various types. For reception of stations located
in many directions, a non-directional type antenna will offer
better results. When using a directional antenna, always
orient it for the best reception of the desired station. The
correct, position will be indicated by highest possible num­
ber of the SIGNAL indicators on the unit.
• To minimize auto-ignition noise,locate the antenna
as far from heavy traffic as possible.
• Keep the feeder or coaxial cable as short as possible.
Do not bundle or roll up excess cable.
• The antenna should be at least two meters (6.5 feet)
from reinforced concrete walls, or metal structures.
FM outdoor antenna connections
FM indoor antenna
In areas close to the transmitting station, the supplied T-
type antenna may suffice. Spread two arms of the antenna
horizontally and position them for the best reception, listen­
ing to an FM station.
The antenna can then be taped to a wall or ceiling and must
not be rounded nor folded. It should be remembered,
however, that the pickup of reflections (similar to "ghosts"
on TV) will result in poor stereo reception. These reflections
must be reduced to a minimum, either by careful orientation
of the T-type antenna or, if this will not eliminate them, by
using a more directional outdoor antenna.
AM antennas
AM loop antenna
Tune to your favorite AM station and position the loop an­
tenna for best reception. Try other stations and find the po­
sition that gives best overall reception.
When this unit is mounted in a rack or placed on a shelf with
insufficient space behind, remove the loop antenna and
hang it from a wall in the direction which gives best recep­
tion. If the length of the lead wire is too short, add a lead
wire of an appropriate length.
Remove from the unit
and hang It from a wall
AM loop antenna adjsutment
AM outdoor antenna
In concrete buildings or at a great distance from the trans-
mitter,„it.rnay be necessary to install an outdoor wire anten­
na. The end of this wire should be stripped of insulation and
connected to the AM terminal.
At this time, keep the loop antenna connected.
Channel space/FM De-emphasis mutual switch
This switch on the rear panel is set to the correct setting
that prevails in the area to which the unit is shipped.
Flowever, if the CFIANNEL SPACE setting is not matched to
the area where the receiver is to be used; for instance, when
you moved from area ® to area ® or vice-versa, desired
reception of FM/AM broadcasts is not expected. In this
case, change the CFIANNEL SPACE setting in accordance
with the area corresponding to the table shown below so
that the FM De-EMPFIASIS setting is matched automatical­
ly.
