While listening 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 broad- casts.

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 treble con- trol.

Try changing the location, height andlor direction of the antenna.

If an indoor antenna is being used, change to an outdoor antenna.

Try using an antenna with more elements.

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.

While listening to AM broadcasts

An unusual "beat" sound is heard.

A low-pitched "hum" sound is heard when the broadcast is tuned.

A strange hissing noise is produced continuously or Intermittently.

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 con- trol.

Place the antenna connection wires and the power cord farther apart.

Install a special outdoor antenna.

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

Install noise-prevention equipment on this unit or on the electric appliance.

Problems noted at all times

Power will not switch ON.

The power cord plug is not completely inserted.

• Confirm that the power cord plug is connected

completely.

No sound is heard when the power is switched ON.

Sound stops during a performance, or no sound Is heard when the power is switched ON.

(The word "OVERLOAD" appears on the display.)

Remote control transmitter does not function,

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

The incorrect input selector has been pressed.

The speaker select indicators are turned off. 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 volume, excessive power and in an excessively hot environment.

Batteries are incorrectly installed.

The remote control transmitter batteries are drained.

There is an obstruction between the remote control transmitter and the receiver, TV or VCR.

The remote control transmitter is not correctly facing the receiver, TV or VCR.

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.

 

 

 

 

 

 

 

 

Insert

the batteries

so

that

the

positive (+)

and

 

negative (-) polarities are correct.

 

 

Replace

them with

new batteries.

 

 

Remove

the obstruction.
