Problem Probable cause(s)
Suggested remedy
While listening to FM broadcasts
An unusual hissing noise is
heard when listening to the
broadcast in stereo, but not
heard when listening
monaurally.
A slight noise may be heard because the method
used for modulation of FM stereo broadcasts is
different than that used for monaural broadcasts.
• Try reducing the treble sound by using the treble
control.
• Set the FM mode selector to the monaural position.
(Note that the broadcast will then be heard as
monaural sound.)
• 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.
The FM stereo indicator or
the quartz lock Indicator
flickers, without completely
illuminating.
Poor location and/or direction of the antenna.
• 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.
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).]
Sound Is distorted,
“popping” noise Is heard,
and/or the volume level
becomes low.
Broadcast signals are being disturbed by nearby
automobile traffic or airplanes.
• Relocate the antenna and the connection wires to a
place farther away from where automobiles pass.
While listening to AM broadcasts
An unusual “beat” sound is
heard.
Unit is being used at the same time as the
television set.
• Turn off the television set, or use this unit farther
away from it.
Interference from adjacent broadcast signal.
• Try reducing the treble sound by using the treble
control.
A low-pitched “hum” sound
is heard when the
broadcast is tuned.
The AM loop antenna connection wires are too
close to the power cord.
• Place the antenna connection wires and the power
cord farther apart.
The power supply frequency from the power cord
is modulated and heard from the speakers.
• Install a special outdoor antenna.
A strange hissing noise is
produced continuously or
intermittently.
Caused by the “discharge phenomenon" and the
"oscillation phenomenon" of electric appliances
(such as fluorescent lights, TV, small series-type
motors, rectification equipment, etc.).
• Try placing this unit farther away from such
equipment.
• Install noise-prevention equipment on this unit or on
the electric appliance.
