Connection (FM antenna)
CAUTION:
<
Turn off the power of all the equipment before making
connections.
<
Read instructions of each component you intend to use with
this unit.
<
Be sure to insert each plug securely. To prevent hum and
noise, do not bundle the connection cords with the power
cord or speaker cables.
FM Indoor Antenna
Connect the lead-type FM antenna to the "FM 75" socket,
extend the lead and tune the tuner to your favorite FM station
(see page 24). Adjust the antenna in a suitable location like a
window frame or wall until the reception is best and then affix
the antenna in that position using thumb tacks, push pins or any
other suitable means.
FM Outdoor Antenna
In an area where FM signals are weak, it will be necessary to
use an 75-ohm unbalanced-type outdoor FM antenna.
Generally, a 3-element antenna will be sufficient; if you live in
an area where the FM signals are particularly weak, it may be
necessary to use one with 5 or more elements.
<
Disconnect the FM indoor antenna when using an outdoor
antenna.

Connection (AM antenna)
How to connect:
Connect the loop antenna's wires to the AM antenna
terminals.
Make sure to connect:
white wire q lower terminal
black wire q upper terminal (GND)
Place the antenna on a shelf or hang it on a window frame,
etc., in the direction which gives the best reception. Keep all
other wires such as power cords, speaker wires or
interconnect wires as far away as possible from the antenna.
AM Indoor Loop Antenna
The high-performance AM loop antenna provided with this
unit is sufficient for good reception in most areas.
To stand the loop antenna on a surface, fix the claw to the
slot in the antenna base.
AM Loop
Antenna
AM Outdoor
Antenna
AM Outdoor Antenna
If the AM loop antenna provided does not deliver sufficient
reception (often due to being too far from the transmitter or
in a concrete building, etc.), it may be necessary to use an
outdoor AM antenna.
Use either a high quality commercial AM antenna or, if not
available, an insulated wire more than 5 m long, strip one
end, and connect this to the terminal as shown.
The antenna wire should be strung outdoors or indoors near
a window. For better reception, connect the GND terminal to
a reliable ground.
Note:
Even when using an outdoor AM antenna, do not disconnect
the AM loop antenna.
