AM Loop Antenna Indoor FM Antenna Audio connection cord 3  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. Outdoor FM antenna Outdoor AM antenna Indoor FM antenna (included) FM ANT AM loop antenna (included) GND AM ANT 75Ω UNBAL. 75-ohm antenna adapter 300-ohm feeder 75-ohm coaxial cable 4 75-ohm/300-ohm antenna adapter Ground  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 2 Orient so that the best reception is obtained. 1 3 * 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. 300-ohm feeder cable 75-ohm coaxial 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 75-ohm/300-ohm antenna adapter 75-ohm coaxial cable 75-ohm antenna adapter 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. 5  m Optional outdoor AM 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. In steel buildings or at a great distance from the transmitter, it may be necessary to install an outside long wire antenna. 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”) OUTPUT terminals are connected to the corresponding (left and right) input terminals of the amplifier or other component.

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 AFFAIRS INFO SPORT EDUCATE DRAMA 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. VARIED POP M ROCK M Sport: Program concerned with any aspect of sport. MOR M Education: Program intended primarily to educate, of which the formal element is fundamental.

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 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 STEREO 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 properly. 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. AM A desired station cannot be tuned in with Automatic tuning. 18 REMEDY 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.  SPECIFICATIONS FM SECTION AM (MW) SECTION Tuning Range [U.S.A. and Canada models] ...................87.5 to 107.9 MHz [U.K., Australia, Europe and General models] ..................................................................87.5 to 108 MHz 50 dB Quieting Sensitivity (IHF) [Except Europe model] 75 ohms Mono ..........................................1.6 µV (15.3 dBf) 75 ohms Stereo ..........................................21 µV (37.7 dBf) Usable Sensitivity [Except Europe model] 75 ohms, 1 kHz, 100% mod.
