INTRODUCTION PREPARATION I Tuner Problem FM stereo reception is noisy. There is distortion, and clear reception cannot be obtained even with a good FM FM antenna. The desired station cannot be tuned in with the automatic tuning method. Previously preset stations can no longer be tuned in. The desired station cannot be tuned in with the automatic tuning method. There are continuous AM crackling and hissing noises. There are buzzing and whining noises (especially in the evening). TROUBLESHOOTING Cause Remedy The characteristics of FM stereo broadcasts may cause this problem when the transmitter is too far away or the antenna input is poor. There is multipath interference. Check the antenna connections. Try using a high-quality directional FM antenna. Use the manual tuning method. Adjust the antenna position to eliminate multipath interference. Refer to page 30, 31 30 The station is too weak. Use the manual tuning method. Use a high-quality directional FM antenna. 30, 31 The unit has been disconnected for a long period. Re-store the stations. The signal is weak or the antenna connections are loose. Noises result from lightning, fluorescent lamps, motors, thermostats and other electrical equipment. Tighten the AM loop antenna connections and orient it for best reception. Use the manual tuning method. Use an outdoor antenna and a ground wire. This will help somewhat, but it is difficult to eliminate all noise. A TV set is being used nearby. Move this unit away from the TV. 32 30, 31 30 - BASIC OPERAIONT ADVANCED OPERATION ADDITIONAL INFORMATION APPENDIX English 69
