ANTENNA CONNEC
® Each antenna should be connected to the designated terminals correctly, referring to the following figure.
e Both AM and FM indoor antennas are included with this unit. In general, these antennas will probably provide
sufficient sensitivity. Furthermore, a properly installed outdoor antenna will give clearer reception than an indoor one. №

Optional outdoor FM antenna
Consult with your dealer or service personnel about the
best method of selecting and erecting an outdoor FM
antenna.
The choice of the feeder cable is also important. Flat
ribbon-shaped twin-lead cable performs well electrically,
and is cheaper and somewhat easier to handle when
routing it through windows and around rooms. Coaxial
cable is more expensive, does a much better job of
minimizing interference, is less prone to the effects of
weather and close-by metal objects, and is nearly as good
a signal conductor as feeder cable, particularly for foam-
type coaxial cables. Coaxial cable is somewhat more
difficult to install at the point where the cable enters the
building. If coaxial cable is selected, make sure the
antenna is designed to be used with that type of cable.

Notes for FM antenna installation |
® To minimize automobile ignition noise, locate the
antenna as far from heavy traffic as possible.
e Keep the feeder cable or coaxial cable as short as
possible. Do not bundle or roll up excess cable.
e The antenna should be at least two meters (6.6 feet)
from reinforced concrete walls or metal structures.
* Australia, U.K. and Europe models need a 75-ohm/300-
ohm antenna adapter (not included) or a 75-ohm
antenna adapter (not included) for connections.

For maximum safety and minimum interference, connect
the GND terminal to a good earth ground if practical. A
good earth ground is a metal stake driven into moist
earth.

This unit can store station frequencies (selected by tuning operation) by using preset station buttons. With this function,
you can select any desired station by only pressing the corresponding preset station button. Up to 40 stations
(8 stations per page) can be programmed.

® For presets, the setting of the reception mode (stereo
or monaural) is stored along with the station frequency.
Memory back-up
The memory back-up circuit prevents the programmed data
from being lost even if the power is cut (for timer use or
due to temporary power failure). If, however, the power is
cut (because of disconnection of the AC power plug etc.)
for more than two weeks, the memory may be erased. If
so, it can be re-programmed by simply following the
PRESET TUNING steps.
If the unit fails to operate normally, check the following points to determine whether the fault can be corrected by the simple measures suggested. If it cannot
be corrected, or if the fault is not listed in the SYMPTOM column, disconnect the power cord and contact your dealer or service center for help.

FM stereo reception is noisy. -
Because of the characteristics of FM stereo
broadcasts, this is limited to cases where the
transmitter is far away or the antenna input is
poor.
Check the antenna connections.
Try using a multiple element FM antenna.

Automatic tuning.
Tighten the AM loop antenna connections and
rotate it for best reception.
Use the manual tuning mode.
There are continuous crackling and hissing
noises. |
These noises result from lightning, fluorescent
lamps, motors, thermostats and other electrical
equipment.
Use an outdoor antenna and a ground wire. This
will help somewhat but it is difficult to eliminate all
noise.
There are buzzing and whining noises
{especially in the evening).
Another station is interfering with the received
station.
This is impossible to remedy.
A television set is being used nearby.
Move the television away.
