FEATURES

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. CONNECTIONS Outdoor FM antenna Outdoor AM antenna AM loop antenna (included) Ground 75-ohm antenna adapter Indoor FM antenna (included) 75-ohm/300-ohm antenna adapter 75-ohm coaxial cable 300-ohm feeder 75Ω UNBAL.FM ANT GND AM ANTConnecting the indoor FM antenna Connecting the AM loop antenna

• 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.

English 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 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.

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. 300-ohm feeder cable 75-ohm coaxial cable 75-ohm antenna adapter 75-ohm coaxial cable Orient so that the best reception is obtained. 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. 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.

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. NOTES ABOUT CONTROLLING THIS UNIT WITH THE REMOTE CONTROL TRANSMITTER This unit has a remote control sensor. It receives signals from a remote control transmitter provided with a YAMAHA amplifier or receiver. Notes

The automatic preset tuning begins from the frequency currently displayed. Received stations are programmed to A1, A2 ... A8 sequentially.

• If more than 8 stations are received, they are also programmed to the preset station numbers on other groups (B, C, D and E) in that order. When the automatic preset tuning is finished The display shows the frequency of the last preset station. Check the contents and the number of preset stations by following the procedure of the section “To recall a preset station” on page 10. To recall a preset station Simply follow the procedure of the section “To recall a preset station” on page 10.

A recalled station is shown by the frequency or station name on the display. Notes

If no station is received by the automatic preset tuning search, the search finishes after “NOTHING” flashes for about 3 seconds on the display.

You can replace a preset station by another FM, MW or LW station manually by simply following the procedure of the section “To store stations” on page 10.

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 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 in to it with the MANUAL TUNING method (in monaural) and program it by following the procedure of the section “To store stations” on page 10.

• 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.

• Parts in shaded area ( ) are present on TX-492RDS only.13 English 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 In areas where RDS broadcasts cannot be received, the RDS broadcast functions do not operate. (The procedures from page 13 to page 17 are not necessary.) This unit can be turned into the following four modes to display RDS data. PS (Program Service name) mode: Displays the name of the RDS station now being received instead of the frequency. PTY (Program Type) 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: Displays information about the program (such as title of the song, name of the singer, etc.) on the RDS station now being received. CT (Clock Time) mode: Displays current time. This signal comes from the RDS station now being received. EON (Enhanced Other Networks) 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. AUTO

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 ST 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 so that “AUTO” lights up on the display. 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.
