Problem Probable cause(s) Suggested remedy
While listening to FM broadcasts
An unusual hissing noise is
hsard when listening to the
broadcast in stereo, but not
heard when listening
monaurally. Due to the differences between a monaural and a
stereo signal, a higher level of signal strength is
required for proper stereo reception. If the signal
level is low, a hissing noise may be produced on
the stereo channel.
*Try reducing the treble sound by using the equalizer
controls.
•Set for monaural reception to reduce the hiss.
Note, however, that the broadcast will not be heard
as stereo.
•Try changing the location, height and/or direction of
the antenna.
•If an indoor antenna is being used, change to an
outdoor antenna.
•Try using an antenna with more elements.
Noise is excessive in both
stereo and monaural
broadcasts. Poor location and/or direction of the antenna.
Transmitting station is too far away.
Excessive distortion in the
sound of stereo broadcasts. Nearby building or mountain.
[Multipath distortion is being caused by the mutual
interference of broadcast signals received directly
from the transmitting station (direct waves) and
signals being reflected from nearby buildings or
mountains (reflected waves).]
•Try changing the location, height and/or direction of
the antenna.
•If an indoor antenna is being used, change to an
outdoor antenna.
•Try using an antenna with more elements.
Sound is distorted,
“popping” noise is heard,
and/or the volume level
becomes low.
Broadcast signals are being disturbed by nearby
