English 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. Amplifier SYMPTOM The unit fails to turn on when the POWER switch is pressed. No sound. The sound suddenly goes off. Only one side speaker outputs the sound. Sound "hums". The volume level is low while playing a record. The volume level cannot be increased, or sound is distorted. Using the BASS, TREBLE and BALANCE controls does not affect the tone. FM stereo reception is noisy. There is distortion and clear reception cannot be obtained even with a good FM antenna. A desired station cannot be tuned in with automatic tuning. 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). The remote control transmitter does not work. The sound is degraded when monitoring is performed by using the headphones connected to the compact disc player or cassette deck which are connected with this unit. CAUSE Power cord is not plugged in or is not completely inserted. Incorrect output cord connections. Appropriate input source is not selected. The TAPE 2 MONITOR switch is ON. The protection circuit has activated because of short circuit etc. The SLEEP timer functioned. Incorrect setting of the BALANCE control Incorrect cord connection. Incorrect cord connections. No connection from the turntable to the GND terminal. The record is being played on a turntable with an MC cartridge. The power to the component connected to the REC OUT terminals of this unit is off. The PURE DIRECT switch is ON. Because of the characteristics of FM stereo broadcasts, this is limited to cases where the transmitter is too far or the antenna input is poor. There is multipath interference. The station is too weak. Weak signal or loose antenna connections. Noises will result from ligtning, fluorescent lamps, motors, thermostats and other electrical equipment. A television set is being used nearby. REMEDY Firmly plug in the power cord. Connect the cords properly. If the problem persists, the cords may be defective. Select an appropriate input source with the INPUT selector. Press the TAPE 2 MONITOR switch to turn it off. Turning the unit off and then on will reset the protection circuit. Cancel the SLEEP timer function. Adjust it to the appropriate position. Connect the cords properly. If the problem persists, the cords may be defective. Firmly connect the audio plugs. If the problem persists, the cords may be defective. Make the GND connection between the turntable and this unit. The player should be connected to the receiver through the MC head amplifier. Turn the power to the component on. The PURE DIRECT switch must be switched OFF to use those controls. Check the antenna connections. Try using a multiple element FM antenna. Adjust antenna placement to eliminate multipath interference. Use Manual tuning mode. Use high quality directional FM antenna. Use Manual tuning mode. Tighten the AM loop antenna connections and rotate it for best reception. Use an outdoor antenna and a ground wire. This will help somewhat but it is difficult to eliminate all noises. Relocate this unit away from the TV. Direct sunlight or lighting (of an inverter type of flourescent lamp etc.) is striking the remote control sensor of the main unit. The batteries of this remote control transmitter are too weak. The power to this unit is off. Change position of the main unit. Replace the batteries with new ones. Turn the power to this unit on.
