CONNECTIONS

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
*If you connect an outdoor FM antenna to this unit, do not connect the indoor FM antenna to this unit. Connecting the AM loop antenna
Orient so that the best reception is obtained.
* 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.

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

300-ohm feeder cable

Notes for FM antenna installation q To minimize automobile ignition noise, locate the antenna as far from heavy traffic as possible. q Keep the feeder cable or coaxial cable as short as possible. Do not bundle or roll up excess cable. q The antenna should be at least two meters (6.6 feet) from reinforced concrete walls or metal structures.
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.
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.
CONNECTIONS TO THE AMPLIFIER
Before making any connections, switch OFF the power to this unit and the amplifier or other component.
Be sure that the connections from the left (L) and right (R) LINE OUT terminals are connected to the corresponding (left and right) input terminals of the amplifier or other component. * When connecting with the YAMAHA amplifier AX-10, connect this units LINE OUT terminals to the TUNER terminals (numbered 2) on the rear of AX-10.

If, however, the power is cut for more than one week, the memory may be erased. If so, it can be re-programmed by simply following the PRESET TUNING steps.
RECEIVING RDS STATIONS (U.K. and Europe models only)
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.

BBC R3

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. 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.

VARIED

AFFAIRS
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.

ROCK M

Education: Program intended primarily to educate, of which the formal element is fundamental.

EDUCATE

M.O.R.: (Middle of the Road Music). Common term to describe music considered to be easylistening, 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:
Drama: All radio plays and serials.

LIGHT M

CULTURE
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.

orchestral CLASSICS Performances of majormusic etc., works, symphonies, chamber and including Grand Opera.

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).
CAUSE Ignition noise from passing vehicles.
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 multipath 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.
Noise from thermostats or other electrical equipment. 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. Insufficient antenna input. Not tuned correctly. 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). 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. AM There is multipath interference.

The ST indicator flickers and reception is noisy.
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.
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.

ABOUT THE ACCESSORY TERMINALS

AC OUTLETS (SWITCHED)

Use these to connect the power cords from your components to this unit. The power to the SWITCHED outlets is controlled by this units POWER switch or the provided remote control transmitters POWER key. These outlets will supply power to any component whenever this unit is turned on. The maximum power (total power consumption of components) that can be connected to the SWITCHED AC OUTLETS is 100 watts.
PRE OUT/MAIN IN terminals
Removing the jumper pins enables this unit to independently perform the functions of a control amplifier and a power amplifier. These terminals are for connection of a signalprocessing system such as a graphic equalizer or sound processor. If a sound processor or other external unit is connected between these terminals, the VOLUME control of this unit can be used for overall adjustment of the level of sound. To connect such a unit, remove the jumper pins from the PRE OUT/MAIN IN terminals, connect the inputs of that unit to the PRE OUT terminals and its outputs to the MAIN IN terminals. For details, refer to the owners manual included with the unit to be connected.
GND terminal (For turntable use)
Connecting the ground wire of the turntable to this terminal will normally minimize hum, but in some cases better results may be obtained with the ground wire disconnected.
Notes If you will not use the PRE OUT/MAIN IN terminals, never remove the jumper pins from these terminals. If removed, no sound will be output from this unit. q If you will use this unit with an external unit connected between the PRE OUT and MAIN IN terminals, make sure that the PURE DIRECT switch on the front panel is turned off. q If you will use this unit as a power amplifier, connect the outputs of an external control amplifier etc. to this units MAIN IN terminals. In that case, this units controls will not function except the PHONES jack and the SPEAKERS switches, so use the controls on the external control amplifier to make volume adjustment etc.
