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.

Connecting the indoor FM antenna Connecting the AM loop antenna
* 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.

English
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 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.
* Use a 75-ohm/300-ohm antenna adapter (not included) or a
75-ohm antenna adapter (not included) for connections.

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.

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.

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.

English
RDS (Radio Data System) is a data transmission system gradually being introduced by FM stations in many countries. Stations
using this system transmit an inaudible stream of data in addition to the normal radio signal.
RDS data contains various information, such as PI (Program Identification), PS (Program Service name), PTY (Program Type), RT
(Radio Text), CT (Clock Time), EON (Enhanced Other Networks), etc.
RDS function is carried out among the network stations.
* This unit utilizes PI, PS, PTY, RT, CT and EON to receive RDS broadcast stations.
Displaying RDS data
In areas where RDS broadcasts cannot be received, the RDS broadcast functions do not operate. (The procedures from page 13 to
page 17 are not necessary.)
This unit can be turned into the following four modes to display
RDS data.
PS (Program Service name) mode:
Displays the name of the RDS station now being received
instead of the frequency.
PTY (Program Type) mode:
Displays the type of the program on the RDS station now being
received. There are 15 program types to classify RDS
stations. Refer to the next page for details.
RT (Radio Text) mode:
Displays information about the program (such as title of the
song, name of the singer, etc.) on the RDS station now being
received.
CT (Clock Time) mode:
Displays current time. This signal comes from the RDS station
now being received.
EON (Enhanced Other Networks)
mode:
Automatically receives a program of the designated program
type when its broadcast starts, in place of the program now
being received. When the broadcast of the called program
ends, the previously received program (or another program on
the same station) is recalled.

will not be selected.
CT mode Current time is displayed in the following form. The CT data
from the station being received changes every minute.
If the data is accidentally cut off, “CT WAIT” may light up. If
the station does not employ the CT data service, this mode
will not be selected.
Frequency The frequency of the station being received is displayed.

Notes
• RDS data service cannot be utilized by this unit if the received signal is not strong enough. Especially, the RT (Radio Text mode)
needs much data to be received, so it may occur that RT mode cannot be displayed even if other RDS modes (PS, PTY, etc.) are
displayed.
• There may be a case that RDS data reception is not possible due to poor reception conditions. If so, press the TUNING MODE
button so that “AUTO” goes off from the display. Though the reception mode is changed to monaural by this operation, when you
change the display to an RDS mode, RDS data may be displayed.
• If the signal strength gets weakened by external interference during receiving an RDS station, the RDS data service may be cut off
suddenly and “
...
WAIT” will light up on the display.

1 Turn the unit into the PTY SEEK mode.
* The program type of the station now being received or
“NEWS” flashes on the display.
2 Select the desired program type.
3 Begin searching all preset RDS stations.
* “PTY HOLD” lights up on the display.
• If a station which broadcasts a program of the program
type is found, the unit stops at the station and displays the
frequency of the station. If the station has PS data, after
that, it turns into the PS mode.
• If the called station is not the desired one, press the PTY
SEEK START button once more.
The unit begins searching for another station which
broadcasts a program of the same program type.
• If no station is found, “NOTHING” appears and then
returns to frequency display. If the station has PS data,
after that, it turns into the PS mode.
* If the PTY SEEK START button is pressed once more
during searching, this mode is canceled and turns into
the frequency display. If the station has PS data, after
that, it turns into the PS mode.
To cancel this function
If the PTY SEEK MODE button is pressed once more, the
PTY SEEK mode is canceled and turns into the frequency
display. If the station has PS data, after that, it turns into the
PS mode.
Calling a program of your desired program type
from among preset RDS stations (PTY SEEK)
By designating a program type, the unit automatically searches all preset stations for an RDS station which broadcasts a program of
that program type.
* There are 15 program types to classify RDS stations. For details, refer to page 14.

Making this unit call a program of your desired program type automatically
when its broadcast starts
This function uses the EON (Enhanced Other Networks) data service on the RDS station network.
By only selecting a desired program type (NEWS, INFO, AFFAIRS or SPORT), this unit automatically searches all preset RDS
stations for a station that broadcasts a program of that program type in the background, and, if found, receives a program when its
broadcast starts in place of the program now being received.
* This function can be used only when an RDS station that employs the EON-PTY data service is received. (When such a station is
received, “EON” lights up on the display.)

TROUBLESHOOTING
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 authorized YAMAHA dealer or service center for help.
SYMPTOM
Crackling sounds from time to time
(especially in weak signal areas).
FM stereo reception is noisy.
The ST indicator flickers and reception is
noisy.
There is distortion and clear reception
cannot be obtained even with a good FM
antenna.
No stereo effect even with a stereo
broadcast.
A desired station cannot be tuned in with
Automatic tuning.
Previously preset stations can no longer
be tuned in.
Insufficient sensitivity.
A desired station cannot be tuned in with
Automatic tuning.
There are continuous crackling and
hissing noises.
There are buzzing and whining noises
(especially in the evening).
CAUSE
Ignition noise from passing vehicles.
Noise from thermostats or other electrical
equipment.
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.
Insufficient antenna input.
Not tuned correctly.
There is multipath interference.
The TUNING MODE button is set to the
manual tuning mode.
The station is too weak.
The tuner has been unplugged for a long
period.
Weak signal or loose antenna connections.
These noises result from lightning,
fluorescent lamps, motors, thermostats and
other electrical equipment.
Another station is interfering with the
received station.
A television set is being used nearby.
REMEDY
The FM antenna should be put up as high
as possible, away from the road, and a
coaxial cable used.
Attach a noise suppressor to the equipment
causing the noise.
Check the antenna connections.
Try using a high quality directional FM
antenna.
Set the TUNING MODE button to the
manual tuning mode.
Use an antenna appropriate for the
reception condition in your area.
Tune again.
Adjust antenna placement to eliminate multi-
path interference.
Set the button so that “AUTO” lights up on
the display.
Use the manual tuning mode.
Use a high quality directional FM antenna.
Repeat the presetting procedure.
Tighten the AM loop antenna connections
and rotate it for best reception.
Use the manual tuning mode.
Use an outdoor antenna and a ground wire.
This will help somewhat but it is difficult to
eliminate all noises.
This is impossible to remedy.
Relocate this unit away from the TV.
