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 16. To recall a preset station Simply follow the procedure of the section “To recall a preset station” on page 16. 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 or AM station manually by simply following the procedure of the section “To store stations” on page 16. ● If the number of received stations is not enough to be stored up to E8, the search will be 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 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 16. 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 buttons after pressing the MEMORY button in step 2 before the automatic preset tuning begins. 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. 17  EXCHANGING PRESET STATIONS You can exchange the places of two preset stations with each other as shown below. 2, 4 TUNER POWER CD TAPE MONITOR AUX PHONO PRESET STATIONS A/B/C/D/E 1 2 3 4 5 6 7 8 VOLUME TUNING MODE FM/AM DOWN TUNING EDIT MEMORY UP l8 l6 20 l4 l2 24 AUTO/MAN'L MONO l0 MAN'L/AUTO FM 28 8 34 6 4 40 PHONES SPEAKERS A B ON ON OFF OFF l BASS 0 TREBLE 0 l l l BALANCE 0 l l LOUDNESS FLAT l 3 50 -30dB 2 2 3 3 4 4 5 5 2 2 3 3 4 4 5 5 2 2 3 3 4 4 L 5 5 R 2 I0 3 9 4 8 5 6 2 60 l 70 0 –dB 7 Example) If you want to shift the preset station on E1 to A5, and vice versa. 1 2 Recall the preset station on E1 (by following the method of “To recall a preset station” on page 16). 4 EDIT EDIT Shows the exchange of stations is completed.

Replace both batteries with new ones. Notes ● Use only AA, R6, UM-3 batteries for replacement. ● Be sure the polarities are correct. (See the illustration inside the battery compartment.) ● Remove the batteries if the remote control transmitter will not be used for an extended period of time. ● If batteries leak, dispose of them immediately. Avoid touching the leaked material or letting it come in contact with clothing, etc. Clean the battery compartment thoroughly before installing new batteries. Notes ● There should be no large obstacles between the remote control transmitter and the main unit. ● If the remote control sensor is directly illuminated by strong lighting (especially an inverter type of fluorescent lamp etc.), it might cause the remote control transmitter not to work correctly. In this case, reposition the main unit to avoid direct lighting. 19  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 Amplifier REMEDY Power cord is not plugged in or is not completely inserted. Firmly plug in the power cord. No sound. Incorrect output cord connections. Connect the cords properly. If the problem persists, the cords may be defective. Appropriate input selector button is not pressed. Press the appropriate input selector button corresponding to the input source. The SPEAKERS switches are not set properly. Set the SPEAKERS switch that corresponds to the speakers to be used to the ON position. Speaker connections are not secure. Secure the connections. The protection circuit has been activated because of short circuit etc. Turning the unit off and then on will reset the protection circuit. The SLEEP timer functioned. Cancel the SLEEP timer function. Incorrect setting of the BALANCE control. Adjust it to the appropriate position. Incorrect cord connections. Connect the cords properly. If the problem persists, the cords may be defective. There is a lack of bass, and no ambience. The + and – wires are connected in reverse at this unit or speakers. Connect the speaker wires in the correct phase (+ and –). Sound “hums”. Incorrect cord connections. Firmly connect the audio plugs. If the problem persists, the cords may be defective. No connection from the turntable to the GND terminal. Make the GND connection between the turntable and this unit. Sound level is low. The LOUDNESS control is functioning. Set the LOUDNESS control to the FLAT position. The volume level is low while playing a record. The record is being played on a turntable with an MC cartridge. The player should be connected to the unit through an MC head amplifier (available separately). The volume level cannot be increased, or sound is distorted. The power to the component connected to the REC OUT terminals of this unit is off. Turn the power to the component on. FM stereo reception is noisy. Because of the characteristics of FM stereo broadcasts, this is limited to cases where the transmitter is too 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. 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. A desired station cannot be tuned in with the automatic tuning method. The station is too weak. Use the manual tuning method. 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. A desired station cannot be tuned in with the automatic tuning method. Weak signal or loose antenna connections. Tighten the AM loop antenna connections and rotate it for best reception. There are continuous crackling and hissing noises. Noises will result from ligtning, 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 noise. There are buzzing and whining noises (especially in the evening). A television set is being used nearby. Relocate this unit away from the TV. The remote control transmitter does not work. Direct sunlight or lighting (of an inverter type of flourescent lamp etc.) is striking the remote control sensor of the main unit. Change the position of the main unit. The batteries of this remote control transmitter are too weak. Replace the batteries with new ones. The power to this unit is off. Turn the power to this unit on. The sound suddenly goes off. FM CAUSE The unit fails to turn on when the POWER switch is pressed. Only one side speaker outputs the sound. Others Remote control transmitter AM Use the manual tuning method. 20 The sound is degraded when listening with the headphones connected to the compact disc player or cassette deck that are connected with this unit.  AUDIO SECTION Minimum RMS Output Power per Channel 8 ohms, 1 kHz, 0.04% THD............................80W+80W 6 ohms, 1 kHz, 0.06% THD............................90W+90W Dynamic Power per Channel (by IHF Dynamic Headroom measuring method) 8/6/4/2 ohms ..................................100/120/145/170W Power Band Width 8 ohms, 40W, 0.08% THD....................10 Hz to 50 kHz Damping Factor 8 ohms, 20 Hz to 20 kHz ............................100 or more Input Sensitivity/Impedance PHONO MM......................................2.5 mV/47 k-ohms CD/TAPE/AUX..................................150 mV/47 k-ohms Maximum Input Signal (1 kHz, 0.04% THD) PHONO MM.........................................................90 mV Signal-to-Noise Ratio (IHF-A Network) PHONO MM to REC OUT (5 mV Input Shorted) ............................................82 dB CD/TAPE/AUX to SP OUT (Input Shorted) .........108 dB English SPECIFICATIONS Residual Noise (IHF-A Network)...........................100 µV Channel Separation (Vol. –30 dB, EFFECT OFF) CD/TAPE/AUX (Input 5.1 k-ohms Terminated, 1 kHz) ................60 dB Tone Control Characteristics BASS: Boost/cut ....................................±10 dB (50 Hz) Turnover Frequency .............................(350 Hz) TREBLE: Boost/cut ..............................±10 dB (20 kHz) Turnover Frequency ........................(3.5 kHz) Continuous Loudness Control...................– 30 dB (1 kHz) (Level related equalization) FM SECTION Tuning Range .....................................87.5 to 107.9 MHz Output Level REC OUT...........................................................150 mV Headphone Jack Rated Output/Impedance Output Level (8 ohms, 0.04% THD)......................0.48V Impedance......................................................390 ohms Frequency Response (20 Hz to 20 kHz) CD/TAPE/AUX .................................................0±0.5 dB RIAA Equalization Deviation PHONO MM.....................................................0±0.5 dB 50 dB Quieting Sensitivity (IHF, 75 ohms) Mono...................................................1.55 µV (15.1 dBf) Stereo ....................................................21 µV (37.7 dBf) Usable Sensitivity (75 ohms) (30 dB S/N Quieting, 1 kHz, 100% mod.) ................................................................0.8 µV (9.3 dBf) Image Response Ratio ...........................................45 dB IF Response Ratio ..................................................80 dB Spurious Response Ratio .......................................70 dB Total Harmonic Distortion PHONO MM to REC OUT 20 Hz to 20 kHz, 1V ...........................................0.02% CD/TAPE/AUX to SP OUT 20 Hz to 20 kHz, 35W/8 ohms ...........................0.02% AM Suppression Ratio ............................................55 dB Capture Ratio.........................................................1.5 dB Alternate Channel Selectivity ..................................85 dB 21  Signal-to-Noise Ratio (IHF) Mono/Stereo......................................80 dB/75 dB Harmonic Distortion Mono/Stereo (1kHz, 40 kHz Dev.) ................0.1%/0.2% Stereo Separation (1 kHz) ......................................50 dB Frequency Response 20 Hz to 15 kHz ..............................................0 ±1.5 dB AM SECTION GENERAL Power Supply [U.S.A. and Canada models]................AC 120V, 60 Hz Power Consumption [U.S.A. model].....................................................145W [Canada model]......................................260VA, 210W AC Outlets 2 SWITCHED OUTLETS [U.S.A. and Canada models]................100W max. total Tuning Range .......................................530 to 1,710 kHz Usable Sensitivity .............................................100 µV/m Dimensions (W x H x D) ...............435 x 146 x 308.5 mm (17-1/8” x 5-3/4” x 12-1/8”) Selectivity................................................................32 dB Weight ..............................................7.8 kg (17 lbs. 3 oz.)
