An unusual hissing noise is
heard when listening to the
broadcast in stereo,
but not
heard when listening
monauraily.
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. (®)
e Try changing the location, height and/or direction
of the antenna, (i®)
® If an indoor antenna is being used, change to an
outdoor antenna. (Ì0))
© Try using an antenna with more elements.
Noise is excessive in both
stereo and monaural broad
casts.
Poor location and/or direction of the antenna.
Transmitting station is too far away.
The “STEREO” indicator or
the “TUNED” indicator flick
ers, without completely illu
minating.
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. (®)

Transmitting station is too far away.
Excessive distortion in the
sound of stereo broadcasts.
Nearby building or mountain.
Whsie 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 station 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.
9 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 equip

The protection circuitry has functioned because
the positive and negative speaker connection
wires have “shorted,” speaker systems with an
impedance less than the indicated rated
impedance of this unit have been used or are
under severe use, such as through excessive vol
ume, excessive power or being in an excessively
hot environment.
• Switch off the power, and after determining and
correcting the cause, switch on the power once
again.
• Use a speaker system of the proper impedance
rating. (®-®)
