SUPPLIED ACCESSORIES
After unpacking, check that the following parts are contained.
AM Loop Antenna Indoor FM Antenna Audio connection cord
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.

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.

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 AF (Alternative Frequencies for the same program station), PI (Program
Identification), PS (Program Service station name), PTY (Program Type name), etc.
RDS function is carried out among the network stations.
* This unit utilizes AF, PI, PS and PTY to receive RDS broadcast stations.
Displaying RDS data
This unit can be turned into the following two modes to display RDS data.
PS (Program Service station name) mode:
Displays the name of the RDS station now being received instead of the frequency.
PTY (Program Type name) mode:
Displays the program type of the RDS station now being received. There are 15 program types to classify RDS stations as follows.
News:
Short accounts of facts, events and publicly
expressed views, reportage and actuality.
Current affairs:
Topical program expanding or enlarging
upon the news, generally in different
presentation style or concept, including
documentary debate, or analysis
Information:
Program whose purpose is to impart advice
in the widest sense, including meteorological
reports and forecasts, consumer affairs,
medical help, etc.
Sport:
Program concerned with any aspect of sport.
Education:
Program intended primarily to educate, of
which the formal element is fundamental.
Drama:
All radio plays and serials.
Culture:
Programs concerned with any aspect of
national or regional culture, including
religious affairs, philosophy, social science,
language, theatre, etc.
Science:
Programs about the natural sciences and
technology.
Varied:
Used for mainly speech-based programs
usually of light-entertainment nature, not
covered by above categories. Examples are:
quizzes, panel games, personality interviews,
comedy and satire.
Pop:
Commercial music, which would generally be
considered to be of current popular appeal,
often featuring in current or recent record
sales charts.
Rock:
Contemporary modern music, usually written
and performed by young musicians.
M.O.R.:
(Middle of the Road Music). Common term to
describe music considered to be “easy-
listening”, as opposed to Pop, Rock or
Classical. Music in this category is often but
not always, vocal, and usually of short
duration (<5 min.)
Light classics:
Classical Musical for general, rather than
specialist appreciation. Examples of music in
this category are instrumental music, and
vocal or choral works.
Serious classics:
Performances of major orchestral works,
symphonies, chamber music etc., and
including Grand Opera.
Other music:
Musical styles not fitting into any of the
above categories. Particularly used for
specialist music, of which Jazz, Rhythm &
Blues, Folk, Country, and Reggae are
examples.

You can call a desired RDS station stored in this unit by only inputting the name of the station in the PS mode. By this operation,
this unit searches all preset stations for the station. You do not have to input a full name, even only the first letter can be used for
calling. As many as 8 letters and/or numerals can be selected for inputting a name.

Calling a preset RDS station by the program type (PTY SEEK)
By designating a program type, the unit automatically searches all preset stations for RDS stations of that program type.
* There are 15 program types to classify RDS stations. For details, refer to page 13.
1 Turn the unit into the PTY mode.
* If “NO PTY” flashes, proceed to the next step while
flashing. If “NO PTY” disappears before you proceed to the
next step, press the FREQ/PS/PTY button once or twice.

3 Select the desired program type.
* By turning the TUNING control, the display will change
program types in sequence.
4 When the desired program type appears, press the
ENTER button.
5
The unit begins searching all preset stations, and calls a
station of the program type if such a station is found.
* When the TUNING control is turned clockwise, the search
is performed from “A1” toward higher numbers of the
preset stations (A1, A2 ... A8, B1, B2, ...). If, however,
“A3” is currently being called for example, the search
begins from the next station “A4”.
When the TUNING control is turned counterclockwise, the
search is performed in reverse order.
If the called station is not the desired one, turn the TUNING
control again to search for another station of the same
program type.
To cancel this function
Press the AF, FREQ/PS/PTY, SHIFT, ENTER, FM/AM or
MEMORY button.
Note
If no station is found by this function, after searching all preset
stations, “NO PTY” flashes for about 3 seconds on the
display, and then it returns to the mode which had been
obtained before the searching was performed.

Calling the best quality RDS station which broadcasts the
same program (AF SEEK)
This function automatically searches for and calls another RDS station of the best reception quality which broadcasts the same
program now you are listening to.
This function utilizes AF (Alternative Frequencies for the same program station) and PI (Program Identification) of RDS data service.
The search is carried out among the RDS network stations.
1 Tune to a desired RDS station.
* Wait for about 10 seconds before proceeding to the
next step. This is for making this unit carry out
searching more stations.
2
The unit searches network stations for other stations with the
same program.
* If the station is not an RDS station, or there is no other
station with the same program, “NO AF” flashes.
Stations with the same program are all stored and
numbered from the best quality station in sequence.
When the search is finished, the best quality station is
called.
3 If desired, you can call the second station by pressing
the AF button.
Whenever the AF button is pressed, stored stations are
called in sequence.
When pressed after the last station is selected, the first one
is restored.
To cancel this function
Press a button other than the AF button.
All of the stored stations will be also cleared.

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 STEREO 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 properly.
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.
