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 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. There is a lack of bass, and no ambience. Sound "hums". CAUSE Power cord is not plugged in or is not completely inserted. Incorrect output cord connections. Appropriate input source is not selected. Speaker connections are not secure. The protection circuit has activated because of short circuit etc. Incorrect setting of the BALANCE control. Incorrect cord connections. The + and - wires are connected in reverse at the amplifier or speakers. Incorrect cord connections. 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. Secure the connections. Turning the unit off and then on will reset the protection circuit. Adjust it to the appropriate position. Connect the cords properly. If the problem persists, the cords may be defective. Connect the speaker wires in the correct phase (+ and -). Firmly connect the audio plugs. If the problem persists, the cords may be defective. Sound level is low. Using the BASS, TREBLE, BALANCE, LOUDNESS controls and SUBSONIC FILTER switch (AX-570 only) does not affect the tone. The remote control transmitter does not work. The distance or range within which the remote control transmitter can be used decreases. No connection from the turntable to the GND terminal. The LOUDNESS control is functioning. The PURE DIRECT switch is ON. Make the GND connection between the turntable and this unit. Set the LOUDNESS control to the FLAT position. The PURE DIRECT switch must be switched OFF to use those controls. 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. Change position of the main unit. Replace the batteries with new ones. 12
