OPERATIONS English 7 En TROUBLESHOOTING TROUBLESHOOTING Refer to the table below when this unit does not function properly. If the problem you are experiencing is not listed below or if the instruction below does not help, turn off this unit, disconnect the power cable, and contact the nearest authorized Yamaha dealer or service center. ¦ Tuner Problem Cause Remedy See page FM FM stereo reception is noisy. The characteristics of FM stereo broadcasts may cause this problem when the transmitter is too far away or the antenna input is poor. Check the antenna connections. 3 Try using a high-quality directional FM antenna. — There is distortion, and clear reception cannot be obtained even with a good FM antenna. There is multi-path interference. Adjust the antenna position to eliminate multi-path interference. — The desired station cannot be tuned into with the automatic tuning method. The signal is too weak. Use a high-quality directional FM antenna. — Use the manual tuning method. 4 The Radio Data System information does not appear. The Radio Data System information is not provided by the radio station. The signal is too weak. Use a high-quality directional FM antenna. — AM The desired station cannot be tuned into with the automatic tuning method. The signal is weak or the antenna connections are loose. Tighten the AM loop antenna connections and orient it for the best reception. — Use the manual tuning method. 4 There are continuous crackling and hissing noises. Noise can result from lightning, 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. A TV set is being used nearby. Move this unit away from the TV set. — ¦ General Problem Cause Remedy See page This unit fails to turn on when POWER is pressed. The power cord is not connected or the plug is not completely inserted. Connect the power cord firmly. 3 This unit has been exposed to a strong external electric shock (such as lightning or strong static electricity). Disconnect the power cord, plug it back in after 30 seconds, then use it normally. — A “humming” sound can be heard. Incorrect cable connections. Firmly connect the audio connection cord plugs. If the problem persists, the cables may be defective. — This unit does not operate properly. The internal microcomputer has been frozen by an external electric shock (such as lightning or excessive static electricity) or by a power supply with low voltage. Disconnect the AC power plug from the outlet and then plug it in again after about 30 seconds. 3 8 En SPECIFICATIONS SPECIFICATIONS AUDIO SECTION • Output Level/Impedance (fixed) FM (40 kHz Dev., 1kHz) .......................................... 1.0 V/1.2 k.
