Keep this manual in a safe place for future reference. 12. Voltage Selector (General Model only) The voltage selector on the rear panel of this unit must be set for your local main voltage BEFORE plugging into the AC main supply. Voltages are 110-120/220-240V AC, 50/60 Hz. FREQUENCY STEP switch (General Model only) Because the interstation frequency spacing differs in different areas, set the FREQUENCY STEP switch (located at the rear) according to the frequency spacing in your area. Before setting this switch, disconnect the AC power plug of this unit from the AC outlet. IMPORTANT Please record the serial number of this unit in the space below. Serial No.: The serial number is located on the rear of the unit. Retain this Owner’s Manual in a safe place for future reference. WARNING TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE. The apparatus is not disconnected from the AC power source as long as it is connected to the wall outlet, even if the apparatus itself is turned off. For U.K. customers If the socket outlets in the home are not suitable for the plug supplied with this appliance, it should be cut off and an appropriate 3 pin plug fitted. For details, refer to the instructions described below. Note: The plug severed from the mains lead must be destroyed, as a plug with bared flexible cord is hazardous if engaged in a live socket outlet. Special Instructions for U.K. Model IMPORTANT THE WIRES IN THE MAINS LEAD ARE COLOURED IN ACCORDANCE WITH THE FOLLOWING CODE: Blue: NEUTRAL Brown: LIVE The colours of the wires in the mains lead of this apparatus may not correspond with the coloured markings identifying the terminals in your plug. Proceed as follows: the wire which is coloured BLUE must be connected to the terminal which is marked with the letter N or coloured BLACK. The wire which is coloured BROWN must be connected to the terminal which is marked with the letter L or coloured RED. Making sure that neither core is connected to the earth terminal of the three pin plug. 3  CONNECTIONS Never plug in this unit and other components until all connections are completed. 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 GND AM loop antenna (included) AM ANT 75Ω UNBAL. 75-ohm antenna adapter 300-ohm feeder 75-ohm coaxial cable 4 75-ohm/300-ohm antenna adapter Ground  English Connecting the indoor FM antenna Connecting the AM loop antenna 1 2 3 2 1 3 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. 300-ohm feeder cable 75-ohm coaxial 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 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. 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. 5  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. ● If you have a YAMAHA amplifier whose terminals on the rear panel are numbered as 1, 2, 3, etc., connections can be made easily by making sure to connect the LINE OUT terminals of this unit to the input terminals of the amplifier numbered 2.

(The procedures from page 13 to page 17 are not necessary.) 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 AUTO PS PTY RT CT EON ST SPORT This unit can be turned into the following four modes to display RDS data. PS (Program Service name) mode: CT (Clock Time) mode: Displays the name of the RDS station now being received instead of the frequency. Displays current time. This signal comes from the RDS station now being received. PTY (Program Type) mode: EON (Enhanced Other Networks) 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: 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. Displays information about the program (such as title of the song, name of the singer, etc.) on the RDS station now being received. 13  Program types in the PTY mode NEWS News: Short accounts of facts, events and publicly expressed views, reportage and actuality. AFFAIRS Current affairs: Topical program expanding or enlarging upon the news, generally in different presentation style or concept, including documentary debate, or analysis. INFO Information: Program whose purpose is to impart advice in the widest sense, including meteorological reports and forecasts, consumer affairs, medical help, etc. SPORT Sport: Program concerned with any aspect of sport. EDUCATE Education: Program intended primarily to educate, of which the formal element is fundamental. DRAMA Drama: All radio plays and serials. CULTURE Culture: Programs concerned with any aspect of national or regional culture, including religious affairs, philosophy, social science, language, theatre, etc. SCIENCE Science: Programs about the natural sciences and technology. 14 VARIED 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 M Pop: Commercial music, which would generally be considered to be of current popular appeal, often featuring in current or recent record sales charts. ROCK M Rock: Contemporary modern music, usually written and performed by young musicians. M.O.R. M 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 M Light classics: Classical Musical for general, rather than specialist appreciation. Examples of music in this category are instrumental music, and vocal or choral works. CLASSICS Serious classics: Performances of major orchestral works, symphonies, chamber music etc., and including Grand Opera. OTHER M 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.  English Changing the RDS modes When an RDS station is received, “PS”, “PTY”, “RT” and/or “CT” that correspond to the RDS data services employed by the station light up on the display. By pressing the RDS MODE/FREQ button once or more, you can change the display mode among the RDS modes employed by the received station in the order shown below. (The RDS mode not employed by the station cannot be selected.) Illumination of the indicator on the head of a name of RDS mode shows that the corresponding RDS mode is now selected. * When an RDS station is received, do not press the RDS MODE/FREQ button until one or some names of RDS modes light up on the display. If the button is pressed before one or some names light up on the display, the mode cannot be changed. This is because the unit has not received all of the RDS data on the station yet. * If no name of RDS mode lights up on the display, the mode cannot be changed. RDS MODE/FREQ PS mode The name of the station being received is displayed. If the station does not employ the PS data service, this mode will not be selected. PTY mode The type of the program on the station being received is displayed. If the station does not employ the PTY data service, this mode will not be selected. (You can make this unit search for a station which is broadcasting a program of your desired program type. For details, refer to the next page.) RT mode Information about the program on the station being received is displayed. Information is displayed by a maximum of 64 Roman Alphabets including umlaut sign. If other characters are used on the RT data, they are displayed with under-bars. If the station does not employ the RT data service, this mode 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. Hour 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 display mode 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. 15  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.

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 AM (MW/LW) FM Crackling sounds from time to time (especially in weak signal areas). 18 CAUSE 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. 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.  English SPECIFICATIONS FM SECTION AM (MW) SECTION Tuning Range ...................................................87.5 to 108 MHz Tuning Range [General model] .........................................530 to 1,710 kHz [U.K., Europe and Singapore models] .......531 to 1,611 kHz Usable Sensitivity ........................................................200 µV/m Selectivity ..........................................................................32 dB Signal-to-Noise Ratio.........................................................50 dB Image Response Ratio ......................................................40 dB Spurious Response Ratio..................................................50 dB Harmonic Distortion; 1 kHz .................................................0.3% 50 dB Quieting Sensitivity (IHF) [Singapore and General models only] 75 ohms Mono ........................................1.55 µV (15.1 dBf) 75 ohms Stereo ..........................................21 µV (37.7 dBf) Usable Sensitivity [U.K. and Europe models only] (DIN) 75 ohms Mono (S/N 26 dB) ........................................0.9 µV 75 ohms Stereo (S/N 46 dB)........................................24 µV AM (LW) SECTION [U.K. and Europe models only] Image Response Ratio [General model] ...........................................................40 dB [U.K., Europe and Singapore models] .........................80 dB IF Response Ratio.............................................................70 dB Spurious Response Ratio [General model] ...........................................................60 dB [U.K., Europe and Singapore models] .........................70 dB Tuning Range .....................................................153 to 288 kHz Usable Sensitivity ........................................................400 µV/m Selectivity ..........................................................................32 dB Signal-to-Noise Ratio.........................................................50 dB Image Response Ratio ......................................................40 dB Spurious Response Ratio..................................................50 dB Harmonic Distortion; 1 kHz .................................................0.3% AUDIO SECTION Alternate Channel Selectivity [General model only]....................................................85 dB Selectivity (two signals, 40 kHz Dev., ±300 kHz) [U.K., Europe and Singapore models only]..................70 dB Signal-to-Noise Ratio [General model] (IHF) Mono..........................................................................82 dB Stereo ........................................................................76 dB [U.K., Europe and Singapore models] (DIN-Weighted) Mono (40 kHz Dev.)...................................................75 dB Stereo (40 kHz Dev.) ................................................70 dB Harmonic Distortion (1 kHz) [Singapore and General models] Mono/Stereo ......................................................0.1%/0.2% [U.K. and Europe models] (40 kHz Dev.)
