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 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 flat ribbon cable 75-ohm coaxial cable 4 75-ohm/300-ohm antenna adapter Ground  English 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 ➁ Orient so that the best reception is obtained. ➂ ➀ * 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”) 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 unit’s LINE OUT terminals to the TUNER terminals (numbered 2) on the rear of AX-10.

If you want to store the first station received by the automatic preset tuning to a desired preset station number. If, for example, you want to store the first received station to C5, select “C5” by using the A/B/C/D/E button and the PRESET STATIONS DOWN/UP buttons after pressing the MEMORY button in step 2. Then press the ENTER button. The first received station is stored to C5, and next stations to C6, C7 ... sequentially. If stations are stored up to E8, the automatic preset tuning is finished automatically. 10 Simply follow the procedure of the section “To recall a preset station” on page 9. <U.K. and Europe models only> * A recalled station is shown by the frequency or station name on the display. Notes ● You can replace a preset station by another FM or AM station manually by simply following the procedure of the section “To store stations” on page 9. <General model only> ● If the number of received stations is not enough to be stored up to E8, the search is finished automatically when it reaches the highest frequency after searching through all frequencies. ● With this function, only FM stations with sufficient signal strength are stored automatically. If the station you want to program is week in signal strength, tune to it in monaural manually and program it by following the procedure of the section “To store stations” on page 9. <U.K. and Europe models only> ● The automatic preset tuning search will be performed through all RDS network frequencies until stations are stored up to E8. If the number of received stations is not enough to be stored up to E8, the search is finished automatically after searching through all frequencies. ● With this function, only RDS stations with sufficient signal strength are stored automatically. If the station you want to program is weak in signal strength, tune to it in monaural manually and program it by following the procedure of the section “To store stations” on page 9. * There may be a case that this function cannot receive a station which could be received by the automatic tuning method. This is because this function receives a large volume of PI (Program Identification) data along with the station.  English EXCHANGING PRESET STATIONS You can exchange the places of two preset stations with each other as shown below. <U.K. and Europe models> <General model> 24 24 Example) If you want to shift the preset station on E1 to A5, and vice versa. 1 Recall the preset station on E1 (by following the method of “To recall a preset station” on page 9). 2 <U.K. and Europe models only> 4 <U.K. and Europe models only> <General model only> KEY MODE <General model only> EDIT ENTER/ KEY MODE ENTER PS/PTY/SEEK SHIFT/ EDIT Press and hold for about 3 seconds. MEMO Shows the exchange of stations is completed. Flashes 3 Next, recall the preset station on A5 by following the same method with step 1. Flashes Memory back-up The memory back-up circuit prevents the programmed data from being lost even if the POWER switch is set off or the power plug is disconnected from the AC outlet or the power is cut due to temporary power failure. 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. 11  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 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. 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 “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. Drama: All radio plays and serials. LIGHT M Culture: Programs concerned with any aspect of national or regional culture, including religious affairs, philosophy, social science, language, theatre, etc. of major orchestral works, CLASSICS Performances symphonies, chamber music etc., and Serious classics: CULTURE SCIENCE 12 Science: Programs about the natural sciences and technology. 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 To turn the unit into the PS mode or PTY mode Press the FREQ/PS/PTY button. Whenever pressed, the mode changes into the PS mode, PTY mode and returns to usual mode in turn. * When an RDS station is received, the display is automatically turned into the PS mode. Do not press the FREQ/PS/PTY button until the display is turned into the PS mode. If the button is pressed before the display mode is changed, it may occur that “NO PS” flashes on the display. This is because the unit has not received all of the RDS data on the station yet. PS mode The name of the station being received is displayed. If the station is not an RDS station, “NO PS” flashes on the display and then returns to usual mode. PTY mode A program type for the station being received is displayed. If the RDS station does not employ the PTY data service, “NO PTY” flashes on the display and then returns to the PS mode.

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. 16 3 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.  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 FM Crackling sounds from time to time (especially in weak signal areas). CAUSE AM 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 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. A desired station cannot be tuned in with Automatic tuning. English TROUBLESHOOTING 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.
