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. 21
Try using a high-quality directional FM
antenna. —
Use the manual tuning method. 45
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. 45
Previously preset
stations can no longer
be tuned into. This unit has been disconnected for a
long period. Set preset stations. 46
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. 45
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. —
