ANTENNA CONNECTIONS
●
●
Each antenna should be connected to the designated terminals correctly, referring to the following figure.
Both AM and FM indoor antennas are included with this unit. In general, these antennas will probably provide sufficient signal
strength. Nevertheless, a properly installed outdoor antenna will give clearer reception than an indoor one. If you experience
poor reception quality, an outdoor antenna may result in improvement.

Orient so that the best
reception is obtained.
* If you connect an outdoor FM antenna to this unit, do not connect the indoor FM antenna to this unit.
* The AM loop antenna should be placed apart from the main unit. The antenna may be hung on a wall.
* The AM loop antenna should be kept connected, even if an outdoor AM antenna is connected to this unit.
m Optional outdoor FM antenna
Consult with your dealer or authorized service center about the
best method of selecting and erecting an outdoor FM antenna.
The choice of the feeder cable is also important. Flat ribbonshaped 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.

m Optional outdoor AM antenna
In steel buildings or at a great distance from the transmitter, it
may be necessary to install an outside long wire antenna.
* Use a 75-ohm/300-ohm antenna adapter (not included) or a

Notes for FM antenna installation
● To minimize automobile ignition noise, locate the antenna
as far from heavy traffic as possible.
● Keep the feeder cable or coaxial cable as short as possible.
Do not bundle or roll up excess cable.
● The antenna should be at least two meters (6.6 feet) from
reinforced concrete walls or metal structures.
GND terminal
For maximum safety and minimum interference, connect
the GND terminal to a good earth ground. A good earth
ground is a metal stake driven into moist earth.

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 authorized YAMAHA dealer or service center for help.
SYMPTOM
FM
Crackling sounds from time to time
(especially in weak signal areas).
CAUSE
AM
REMEDY
Ignition noise from passing vehicles.
The FM antenna should be put up as high
as possible, away from the road, and a
coaxial cable used.
Noise from thermostats or other electrical
equipment.
Attach a noise suppressor to the equipment
causing the noise.
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 high quality directional FM
antenna.
Set the TUNING MODE button to the
manual tuning mode.
The ST indicator flickers and reception is
noisy.
Insufficient antenna input.
Use an antenna appropriate for the
reception condition in your area.
Not tuned correctly.
Tune again.
There is distortion and clear reception
cannot be obtained even with a good FM
antenna.
There is multipath interference.
Adjust antenna placement to eliminate multipath interference.
No stereo effect even with a stereo
broadcast.
The TUNING MODE button is set to the
manual tuning mode.
Set the button so that “AUTO” lights up on
the display.
A desired station cannot be tuned in with
Automatic tuning.
The station is too weak.
Use the manual tuning mode.
Use a high quality directional FM antenna.
Previously preset stations can no longer
be tuned in.
The tuner has been unplugged for a long
period.
Repeat the presetting procedure.
Insufficient sensitivity.
Weak signal or loose antenna connections.
Tighten the AM loop antenna connections
and rotate it for best reception.
A desired station cannot be tuned in with
Automatic tuning.
English
TROUBLESHOOTING
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 noises.
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.
Relocate this unit away from the TV.
