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 dif-
terent than that used for monaural broadcasts.

Noise Is excessive In both
stereo and monaural broad-
casts.

Poor location and/or direction of the antenna.

Transmitting station is too far away.

a Try reducing the treble sound by using the treble con-
trol.

0 Try changing the location, height and/or direction of
the antenna.

a if an indoor antenna is being used, change to an out«
door antenna.

I Try using an antenna with more elements.

The FM stereo Indicator or
the quartz lock Indicator
flickers, without completely
Illumlnating.

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.

0 Try changing the location, height and/or direction of
the antenna.

I If an Indoor antenna is being used. change to an out-
door antenna.

0 Try using an antenna with more elements.

While listening to AM broadcasts

An unuoual "beat" sound It
heard.

Unit is being used at the same time as the televi-
sion set.

0 Turn off the television set, or use this unit farther
away from it.

Interference from adjacent broadcast signals.

a Try reducing the treble sound by using the treble con-
trol.

A low-pitched "hum" sound
In heard when the broad-
cast I: tuned.

The AM loop antenna connection wires are too
close to the power cord.

0 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.

0 install a special outdoor antenna.

A strange hleslng 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).

0 Try placing this unit farther away from such equip-
ment.

Problems noted at all times

No sound I: heard.

Connections are incomplete or incorrect to the
speaker systems, etc.

0 Check to be sure that all connection wires are cor-
rectly connected.

The incorrect input selector has been pressed.

0 Check to be sure that the correct selector is pressed.

The tape monitor function is ON.

0 Press the tape monitor button.

The muting function is ON.

0 Press the muting button.

The speaker indicator is turned off.

0 Turn on the speaker indicator.

Sound stops during a per-
formance, or no sound Is
heard when the power ls
switched ON.

(The word OVERLOAD
appears on the dlsplay.)

The protection circuitry has functioned because the
positive and negative speaker connection wires are
shorted', speaker systems with an impedance
less than the indicated rated impedance of this unit
are used or under severe use, such as loud vol-
ume, excessive power and in an excessively hot
environment.

o Switch off the power, and after determining and cor-
recting the cause, switch on the power once again.
e Use a speaker system of the proper impedance rat-

ing.
