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. 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 Auto tuning. A desired station cannot be tuned in with Auto 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 distance or range within which the remote control transmitter can be used decreases. 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 selector is not pressed. The protection circuit has activated because of short circuit etc. 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. 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. Press the appropriate input selector corresponding to the input source. Turning the unit off and then on will reset the protection circuit. Adjust it to the appropriate position.

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 noise.
