Problem
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.
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 multipath interference. Adjust the antenna position to eliminate
multipath interference.
The desired station
cannot be tuned in
with the automatic
tuning method. The station is too weak. Use the manual tuning method.
Previously preset
stations can no
longer be tuned in. The unit has been disconnected for a long
period. Re-store the stations.
The desired station
cannot be tuned in
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 best reception.
There are continuous
crackling and hissing
noises.
There are buzzing and
whining noises
(especially in the
evening).
Cause Remedy
Refer to
page
Use an outdoor antenna and a ground wire. This
will help somewhat, but it is difficult to
eliminate all noise. Noises result from lightning, fluorescent lamps,
motors, thermostats and other electrical
equipment.
A TV set is being used nearby. Move this unit away from the TV.
The batteries are weak.
