to FM broadcasts
An unusual hissing noise is
heard when listening to the
broadcast in stereo, but not
heard when listening
monaurally.
Noise is excessive in both
stereo and monaural broad-
casts.
The FM stereo indicator or
the quartz lock indicator
flickers, without completely
illuminating.
Excessive distortion in the
sound of stereo broadcasts.
A slight noise may be heard because the method
used for modulation of FM stereo broadcasts is
different than that used for monaural broadcasts.
Poor location and/or direction of the antenna.
Transmitting station is too far away.
Poor location and/or direction of the antenna.
Transmitting station is too far away.
Nearby building or mountain.
• Try reducing the treble sound by using the iJ;e'ble
control. (0)
• Try changing the location, height and/or direction
of the antenna. (O 0)
• If an indoor antenna is being used, change to an
outdoor antenna. (0)
• Try using an antenna with more elements.
• Try changing the location, height and/or direction
of the antenna. (O O)

i While listening to AM
An unusual "beat"
sound is
heard.
A low-pitched "hum"
sound
is heard when the station is
tuned.
A strange hissing noise is
produced continuously
or
intermittently.
broadcasts
Unit is being used at the same time as the
television set.
Interference from adjacent broadcast signal.
The AM loop antenna connection wires are too
close to the power cord.
The power supply frequency from the power cord
is modulated and heard from the speakers.
Caused by the "discharge phenomenon" and the
"oscillation phenomenon" of electric appliances
(such as fluorescent lights, TV, small series-type
motors, rectification equipment, etc.).
• Turn off the television set, or use this unit farther
away from it.
• Try reducing the treble sound by using the treble
control. (0)
• Place the antenna connection wires and the power
cord farther apart.
• Install a special outdoor antenna. (0)

power and in an excessively hot environment.
• Confirm that the power cord plug is connected
completely.
